LED floodlight: how to choose, rating and best manufacturers

Traditionally, floodlights are used when it is necessary to illuminate a large area - warehouses, car parks, the area in front of the house. Previously, floodlights based on incandescent lamps were very powerful and bulky, which significantly limited their scope of application.

With the advent of compact halogen and LED light sources, the scope of applications has expanded significantly. Which type should you choose?

Types of spotlights by light source

• Halogen;
• Metal halide;
• Sodium;
• LED

Halogen

A halogen lamp is used as a light source; this is the same incandescent lamp, the bulb of which is filled with an inert gas, which increases its brightness and service life.

Metal halide

Built on the basis of a gas discharge lamp. They have very high brightness, but their operation requires a special lamp ignition unit and special operating conditions.

Sodium

Uses a gas-discharge lamp, but the flask is filled with sodium vapor which emits light.

LED

The light source is a matrix of bright LEDs. These devices have the most compact dimensions and a long service life.

The best floodlights with a motion sensor for outdoors

How to choose LED lamps for your home: from characteristics to manufacturers

The last of the three types discussed in this article assume the presence of one specific sensor - a motion sensor. With it, the lamp, having detected activity in its area, lights up and stays on for some time (from a couple of seconds to a couple of minutes).

The three most interesting models will be discussed below.

Features of operation of different types of spotlights

The most affordable ones are halogen, they have relatively low energy efficiency - 10-15 lumens/W. The service life of such a lamp is less than 1000 hours. It is most advisable to use them for periodic illumination of small areas, for example, a floodlight with a motion sensor in front of a gate.

Sodium and metal halide lamps have high energy efficiency - 80-120 lumens/W. At the same time, they are quite “capricious” to the ambient temperature, supply voltage, and require time to ignite and turn off. A short-term power outage and an attempt to re-ignite a lamp that has not cooled down can damage it.

LED spotlights are the most convenient and practical for both industrial and domestic use. Energy efficiency at the level of gas-discharge lamps, instant ignition and very long service life make them the most attractive. Ideal for lighting an area.

Lamp type

The second, no less important stage of selection is to decide on the type of light source. Today, floodlights can be LED, halogen, metal halide and sodium. Each option has its own advantages, which we will now consider.

LED

The first and most modern option is LED devices. LEDs are the future, so we need to go into more detail here.

Among the advantages of such devices are:

• low power consumption;
• long service life (over 50 thousand hours);
• vibration resistance;
• high degree of IP protection;
• can be used at temperatures from -30 to +40°C (there are models with an even larger range);
• have an unlimited resource of switching on/off.

And this is not a complete list of the advantages of LED floodlights. As for the disadvantages, there is only one – the high cost of LED products.

Halogen

The second most popular are halogen lamps. Their advantage is low price and high color rendering. As for the disadvantages, the main ones are considered to be a short service life (no more than 4000 hours) and strong heating during prolonged operation (it is impossible to touch the case without gloves).

Many people ask questions about which floodlight is better to choose for yard lighting - halogen or LED. We recommend, if you have money, to give preference to a more modern option, because... Such a lamp pays for itself very quickly and will serve for over 10 years.

Metal halide

Next on the list are metal halide spotlights for lighting. A gas-discharge lamp with high light output is installed inside such devices. Metal halide lamps have a bright, cool glow, which is suitable for construction sites or areas where good lighting needs to be taken care of. Another advantage of choosing this option is high reliability and resistance to voltage surges.

Sodium

Well, the last option is sodium spotlights. For lighting in such devices, sodium gas-discharge lamps are used. The disadvantage of such light sources is poor color rendering, so they are more often used to illuminate the perimeter of buildings and those areas where there are no special requirements for the brightness of the glow. The advantage of choosing sodium floodlights is their versatility - you can easily replace the type of light source with another.

We figured out the types of lamps. I would like to provide a few more facts in favor of LED devices. Firstly, all other alternative options are not resistant to vibration and may fail when vibration occurs. Secondly, LEDs, unlike gas-discharge lamps, do not harm the environment, so they can be disposed of in a regular trash bin. Thirdly, diodes are much stronger than their competitors and can withstand minor mechanical damage, which is not uncommon on the street.

Classification of LED spotlights

The choice of LED spotlight is made based on the tasks assigned to the lighting. The following classifications exist:

Power : from 10 to 500 W.

Brightness : from 700 to 34000 lumens.

IP protection class (Internal Protection):

IP20 - for indoor lighting. No protection from moisture and dust.

IP21 / IP22 - can be used in unheated rooms. Has protection against condensation formation.

IP23 - can be used in unheated rooms and outdoors. Has protection against condensation formation.

IP50 - dust-proof housing. Used in industrial facilities. No waterproofing.

IP54 - waterproof housing. Use in conditions with high humidity.

IP67 / IP68 - Full waterproofing up to the possibility of immersion in water.

By spectrum:

3700-4300 – warm white;

4500-5500 – neutral white;

6000 – cool white;

Floodlight characteristics and options

Protection class (IP)

Floodlight equipment is produced with various IP protection classes, presented in the IPxx format. The first number represents protection from dust/solids, and the second number represents protection from moisture. In the table below you can see the generally accepted classification:

Power, brightness and luminous efficiency

Modern floodlights are available with a power of 10-1000 watts. This range allows us to meet any customer needs for organizing directional lighting and local lighting. Lighting devices differ in luminous efficiency - a characteristic that demonstrates the number of lumens of brightness obtained from 1 Watt of power. Today the light output is more than 100 lm/W.

Touch sensor

Equipping with a motion/light sensor expands the functionality of floodlight equipment. The motion sensor is triggered when a person crosses the border of its coverage area (10-15 meters) in a viewing sector of 120-160 degrees. Infrared, ultrasonic, radio wave sensors are used.

Light sensors respond to changes in the intensity of the luminous flux, recorded by a photocell and analyzed by a detector. The spotlight automatically turns on and off when the light level meets a preset threshold.

Lighting type

LED spotlights shine at a certain solid angle, which determines the range and sector of the illuminated area. Available models:

• long-range – have high power and a narrow light beam (less than 20 degrees);
• flood – illuminate a large sector of space due to a large dispersion angle (over 120 degrees);
• accent - characterized by a narrowly focused light flux (up to 20 degrees).

Selection of spotlight power

The distance at which the LED spotlight shines depends on the power of the matrix. The level of illumination decreases exponentially. Therefore, the illumination area of ​​LED spotlights does not increase in proportion to the increase in power.

For movement in the dark, lighting at a level of 10-15 lux/meter is sufficient, for technical lighting - 75 lux/meter, for precision work - 100 lux/meter.

Criterias of choice

Power

One of the most important parameters of a spotlight is the luminous flux power. The buyer needs to decide in advance on the illuminated area. As a standard, there is a value of illumination measured in lux (lx). The measurement is carried out using a special device called a lux meter. The standards are established by the regulatory document “Natural and artificial lighting” - SNiP 05/23/2010. The selection of a street spotlight is made based on the information provided in the table below.

A comfortable level of illumination is considered to be 10 lux. The light from the Moon provides only 0.27 lux, and the Sun provides illumination at the level of 100 thousand lux. Different tasks require different amounts of light. For example, to work as a jeweler you will need illumination of 300 lux.

When determining the illumination indicator, you need to keep in mind that over time, the brightness of the diodes decreases, which directly affects the quality of the luminous flux. In this regard, it is recommended to take care of the safety margin of the lamp in advance. It is believed that one and a half or even two times the power reserve is required.

The more powerful the spotlight, the larger the area it can illuminate and the fewer pieces of lighting equipment will be needed. To select a spotlight, calculations are carried out.

Input parameters:

• power (100 W);
• The brightness of the diodes for each watt of power is 100 lm.

Note! Brightness is measured in lumens, and this indicator is directly proportional to the illumination. Lux is equal to lumen divided by unit area: lux=lumen/square meter.

Thus, the spotlight produces 10 thousand lm (100 W × 100 lm). Next, we use the above form and calculate the comfortable brightness that the spotlight can provide. To do this, divide 10 thousand lm by 10 lux and get 1000 sq. m. In this case, it is necessary to decide at what distance from the ground to hang a 100 W lamp so that the illumination level of the area is 10 lux. To solve the problem, you will need the following formula: R=5.65√W/L, where W is power (100 W), L is illumination (10 lux). Having carried out the calculations, we obtain the installation height of the spotlight - 25.2 m. If you need to place the spotlight lower, then the power required is not so high.

It should also be taken into account that the formula contains a luminous flux distribution coefficient (5.65). Moreover, this indicator corresponds to lamps with a light beam opening angle of 120 degrees. Manufacturers also produce equipment with a directional flow of light generated by an installed lens.

In such devices, the light beam opens at an angle of 60 degrees. Then another coefficient is used - 10.67. Thus, the recommended installation height of the equipment will almost double. In this regard, spotlights with a beam opening at an angle of 60 degrees are not practical for lighting small objects, such as a country house.

power unit

Another component of the lighting device is the power supply. Today, manufacturers offer a choice of floodlight models with voltages of 12, 24, 36 and 22 V. In the latter case, the operation of the equipment is independent of intermediate units.

Degree of protection

The level of protection of the device from external factors is determined by an alphanumeric code, where the letters (IP) indicate “ingress protection”, and the two numbers following the letters indicate its degree. The higher the number, the more reliable the protection. There are devices with different levels of it:

1. Models with code IP44 can only be used indoors. They are not intended for the street.
2. Lamps with code IP65 and higher are used for street lighting.
3. IP67 is even more resistant. Such equipment can be used not only in a suspended position, but also on the ground.
4. IP68 - highly resistant models that can maintain functionality even when partially or completely immersed in water. They can be used outdoors in the harshest conditions.

Explosion-proof models are also available on the market. They are installed in a special protective housing that can withstand explosions. Floodlights of this subtype are installed where there is an increased risk of fires or explosions.

Prices and quality

There is a huge variety of LED street lighting products on the market. Therefore, the answer to the question of which spotlight is best to buy is complicated.

One of the leading manufacturing companies is Osram. The products of this German company are the most diverse in range and are of high quality. Less known are such manufacturers as Wolta (Germany) and Feron (Russia).

Spotlights are not overly complex in design. In this regard, the cost of the product is influenced not so much by the design of the device, but by the quality of materials, workmanship, and the reputation of the manufacturer.

A 250W spotlight costs approximately 15 thousand rubles. One hundred watt models - from 6 to 7 thousand rubles. (Wolta).

Feron products are cheaper (from 700 rubles). Diode lamps of this brand are characterized by low power - 10 W.

Extra options

The most important criteria when choosing a street floodlight are discussed above. However, there are other parameters that you should pay attention to when buying an outdoor lamp:

1. Floodlights are available in stationary or mobile versions. If the spotlight is mobile, it is equipped with a movable mount and a handle, which allows it to be moved to another location. A mobile spotlight is suitable in cases where temporary illumination of a particular object is organized.
2. It is very convenient to have a motion sensor and photo relay. If the spotlight is equipped with such devices, it will turn on for the following reasons: it has become dark outside or the infrared rays have detected a moving object in the area. The motion sensor and photo relay provide significant savings in electricity consumption and turn the spotlight into an autonomous system.
3. A home spotlight can have a single, but powerful LED or matrix. When choosing the type of lamp, you should keep in mind that the matrix heats up faster and does not have such a high light output.
4. The body of the spotlight can be made of metal or plastic. The best material for a spotlight is metal (aluminum or aluminum alloy). Plastic products are cheaper. However, they are much less durable and do not withstand temperature highs and lows well.
5. There are lamps on sale that can be operated from a battery. It is recommended to purchase such models when the illumination of the area is temporary or there may be cases of power outages.
6. The functionality of the spotlight is affected by its shape. Square lamps illuminate large areas very evenly. But round spotlights provide the most directional flow of light. Linear lights are suitable for illuminating swimming pools and building facades.

Test review of spotlights

Matrix

When manufacturing a spotlight matrix, cluster super-bright diodes or a large matrix with conventional high-brightness SOD diodes can be used. Which LED floodlight is best seen from their technical features.

This is
a spotlight with an SOD matrix , several hundred LEDs are installed on it. Such matrices are cheaper than a cluster of ultra-bright LEDs, but with a large number of light-emitting elements, a scatter in their parameters is inevitable. If one of the LEDs fails, it increases the load on the others. With comparable brightness of matrix and cluster devices, the price of the former is 30-40% less, but the service life is 3-4 times lower.

In cluster spotlights, the matrix is ​​made of ultra-bright LEDs of the 5050, 5630 series with the most identical parameters. The small emitted surface area provides a powerful, uniform flow of light. The effective life reaches 30,000 hours.

Matrix color temperature

The higher the color temperature of the LED, the higher the light output. At a temperature of 6500K and a power of 40 W, the luminous flux will be about 4000 lumens, at a temperature of 5000K - about 3600 lumens, at 3500K - 3000 lumens. Therefore, cold light is more effective for illuminating areas, although it has a blue tint. But for illuminating the work surface and reading, they are worse than the 5000K option, which produces pure white light.

Matrix lamp design

The diode matrix is ​​the substrate on which the LED crystals are located. If one of the crystals breaks, the entire matrix loses functionality. The cost of an LED matrix is ​​high, and therefore conventional lamps are more profitable than matrix lamps. The fact is that in LED lamps it is possible to replace individual diodes, which significantly reduces operating costs.

Due to their design features, light diodes and matrices emit light at a very narrow angle (about 120 degrees). As a result, classification of equipment is difficult. If a lighting device has LEDs or matrices in the same plane, the device is classified as a floodlight.

The power of the LED matrix is ​​most often no higher than 50 W. If there is a need for more power, several matrices are placed in the lamp. The driver in powerful models is located in the inside of the case. As a result, when replacing the driver, it is necessary to dismantle the lamp from its location.

The body of the spotlight is made of aluminum alloy. To gain access to the matrix, unscrew four screws. After this, remove the protective panel with optical glass and reflector. Due to the absence of a gap between the case and the substrate, as well as the presence of thermally conductive paste, it is possible to effectively remove thermal energy from the crystals. Good heat dissipation increases the service life of the floodlight.

There is a network cable on the back side. To ensure tightness, it is crimped with a special nut. Next, the wire enters the panel (clamped with screws) through the silicone layer - towards the lamp body. To allow the spotlight to be placed on a pole, a swivel bracket is provided. The case has vertical fins used to remove heat from the matrix.

The driver is located under the back cover of the device. It transforms a voltage of 220 V into a voltage with a stabilized current suitable for the operation of the matrix.

An example of a street lamp is the DiUS model. The power of individual LEDs is 1 W. The kit includes a driver, which is a sealed dedicated unit connected to the lamp via a connector. The driver is attached to the case using screws. If necessary, it can be easily removed from the printed circuit board.

Halogen or LED spotlight?

Which spotlight is better, LED or halogen, is a very pressing question today. Halogen lights are often considered as an alternative to LEDs. 25-30% lower cost, cheap lamps are the main motivating factors. But in the end, halogen spotlights are significantly inferior to LED ones. Their energy consumption is five times higher, and the service life of the light-emitting element is ten to twenty times less.

Within a year of regular operation, the cost of a halogen lamp will be several times higher than the operating costs of an LED lamp, making its purchase unprofitable.

The best solar floodlights

The controller controls the operation of the spotlight. Its simplest option is a photo relay (light sensor), whose task is to monitor the level of natural light. As it gets darker, the spotlight turns on, and as soon as it becomes light, it turns off accordingly. A more complex, but also more effective programmable controller, which is used in architectural and facade advertising floodlighting. There are more functions here - turning on/off, adjusting the lighting intensity, etc.

How to choose a budget LED floodlight

There are products from several hundred manufacturers on the market. The price of their products may differ significantly from products from brands Philips, Osram, Hyunday. Of course, such giants make the best LED spotlights, but the brands Feron, Luna, and Jazzway have proven themselves well.

You can find domestically produced products a little more expensive than Chinese ones. When compared, the “Chinese” almost always have slightly overestimated data on luminous flux.

These are three budget options under $50. When testing all models, the actual luminous flux turned out to be 5-10% lower. The IP65 degree of protection implies complete protection against the penetration of condensation and dust. In this case, the connection of the body parts is overhead, fixed with screws, and sealed with a thin silicone sealant. This design is unable to meet the requirements of the specified degree of protection.

Most likely, over time, condensation will form inside the case. Manufacturers indicate the operating temperature range is -40 - +60 degrees, but the relatively small radiator area of ​​FERON in summer is not able to adequately remove heat, which reduces the real life of the LED matrix.

Based on operating experience, Foton brand products have proven themselves to be the best among budget models.

What points should you pay attention to when choosing a spotlight?

Housing material

In some models, the housing is made of stainless steel and the reflector housing is made of aluminum. For use inside domestic premises it is not critical, but when installed in an open space at the junction of metals there will be increased corrosion, which will not have the best effect on reliability.

Radiator thickness

Saving on a radiator worsens heat dissipation from the matrix and reduces its actual service life. When choosing between two identical models, choose one with a large cooling radiator.

Protection class

You should not save money by purchasing a spotlight without protection from dust and moisture if the device is planned to be used outdoors. It is better to find a case with protection class IP54/64.

In addition, the range includes stationary, mobile, and wall-mounted options.

LED floodlights for street lighting: technical parameters and design

When choosing an LED lighting device, you need to know its functional features. Such spotlights are usually equipped with a set of diodes.

Power is one of the main indicators of an LED spotlight, which consumes a minimum amount of electricity. Thus, the device will require a minimum network power to operate. The luminaire requires a minimum of 5 W to function. The amount of energy consumed depends on the intended purpose of the device. The most widely used floodlights are 50 W LED floodlights. Such a device, despite its low power consumption, produces light of 4000 lm, which provides effective illumination of a space of 100 m².

LED spotlights consume a minimal amount of electricity

The LED lamp is characterized by the following technical parameters:

1. Long-term operation, which means that the device operates for a long time without requiring repair or replacement of lamps. One diode in constant operation mode can last 100 (or more) thousand hours.
2. High efficiency, which reaches 98%. Thus, the lamps spend energy exclusively for their intended purpose - to create a light flow. They practically do not heat up.
3. An appropriate level of protection, which must be at least IP65. Thus, the device is protected from dust and moisture. Lamps with less protection (IP44) are installed in enclosed areas.
4. Safety for people. LED lamps do not pose a threat to health and do not require special disposal, unlike energy-saving mercury lamps.
5. Elementary installation of the device and ease of maintenance. The lamp is mounted on special brackets, which allows you to adjust the direction of the light.

The device operates for a long time without requiring repair or lamp replacement.

Additional technical parameters of lamps for spotlights depending on their purpose

The size and weight of the spotlight depend on its functional purpose, that is, on the number of diodes and the power of the lamp.

For example, to provide street lighting with 500 W incandescent lamps, you will need to install a large-sized lamp - from 60x60 cm. In turn, a 50 W LED street floodlight has dimensions of 20x20 cm.

Frequent voltage fluctuations adversely affect the service life of the LED lamp

LED lamps for street lighting have different configurations. They can be made in the shape of a square, rectangle, circle, oval or ruler. These lamps are characterized by additional technical parameters:

1. Wide power supply range – from 100 to 240 Volts. If the voltage drops, the LED spotlight continues to operate as usual.
2. Works with both alternating and direct current.
3. A certain number of diodes.
4. Different colors of light - hot or cold, different temperatures.
5. Possibility of changing the light scattering angle. Most often, the installation angle of floodlights for outdoor lighting is 50° or more.

It should be noted that frequent voltage surges adversely affect the service life of the lamp, reducing it. In this case, the starting unit of the searchlight very quickly fails.
