The developers of the new modular Combo lamps tried to eliminate all the shortcomings inherent in conventional LED lamps and lamps:
- thanks to the massive heat sink, the LEDs do not overheat and fail;
- through the use of LEDs with a high color rendering index CRI (Ra)> 90, it is possible to achieve lighting quality that is not inferior to halogen lamps;
- the separation of the LED module and driver increases the reliability of the lamp and allows you to use both the normal and dimmable driver with the same LED module;
- interchangeable reflectors allow you to get different lighting angles;
- Housings and frames in two colors of various shapes allow you to create different lights for different conditions of use on the basis of the same LED modules.
Two types of LED modules are available: with a color temperature of 3000K (warm light) and 4000K (neutral light).
The module is sold for 2746 rubles complete with a non-dimmable driver and a 38 ° or 60 ° reflector. Additionally sold reflectors with angles of 15 °, 25 °, 38 ° and 60 °.
Dimmable driver costs 1627 rubles and is controlled by a conventional dimmer.
Housings of luminaires are available in black and white, round and square, with the possibility of rotation (and, accordingly, the direction of the light beam) and without it. They cost from 712 to 1017 rubles.
To connect the housing and the LED module, a bayonet connection is used, which provides easy installation and reliable fixation of the module.
The luminaire in the housing can be directly mounted on a false ceiling or false wall (the height of the luminaire assembly is less than 80 mm and it can be built into a standard plasterboard ceiling), in addition, it is possible to put the luminaires on frames that are available in two colors and various shapes under one, two or three lamps.
The manufacturer claims the power of the modules is 12 W, the luminous flux of 890 lm for the module with warm light and 1080 lm for the module with neutral light, CRI> 90, the service life of 20,000 hours. Modules have a two year warranty.
I tested LED modules with different diffusers and different drivers. Before testing, the modules warmed up for 30 minutes.
Actual power and luminous flux turned out to be even higher than declared: the module with warm light consumes 13.4 W and gives 928 lm, the module with neutral light consumes 13.8 W and gives 1151 lm.
The color rendering index of the modules is really high, and the “warm” module has a CRI (Ra) of 96.8. It is very good.
The standard non-dimmable driver uses a linear voltage conversion circuit, so the minimum supply voltage at which the lamp brightness decreases by no more than 5% is 200 volts, and the light ripple coefficient is 1.9%.
Dimmable driver is built on a pulse converter. A luminaire with this driver can work without reducing the brightness when lowering the mains voltage to 121 volts. The ripple coefficient of light is 10%. Power Factor (PF) - 0.96. A ten percent ripple can be visible through the smartphone’s camera, but it is completely not visible visually and does not exceed the ripple level of a conventional incandescent lamp.
Measured lighting angles with different reflectors.
In the near future, a new LED module with a dimmable driver and a variable lighting temperature when dimming will be on sale.
Pay attention to the horizontal strip in the center of the phosphor circle. This module uses two types of phosphor and separate control of two groups of LEDs. At low brightness, when dimming, only those LEDs are lit, which are located under the phosphor, giving a yellower light with a color temperature of 2000K. With increasing brightness, LEDs gradually light up under the rest of the phosphor area, giving 3000K, and the light begins to turn white. At full brightness, the color temperature of this module is about 2900K. A more advanced phosphor with the same high overall color rendering index gives more uniform indices of the transmission of individual colors. For comparison, on the left is a standard Combo module with warm light, on the right is a new module.
Paying for even color reproduction is less efficient. The new module consumes more (14.8 W), and gives less light - 864 lm. But the ripple level is reduced to 0.5% and the lamp can work without reducing the brightness when lowering the voltage to 155 volts.
Combo luminaires are manufactured under the Lumker brand (this is one of SWG's premium brands).
Based on one of the four options for the LED module, two driver options, four reflector options, eight body options and sixteen frame options, you can assemble several hundred different luminaires suitable for different applications.
This is not the first time that SWG has offered such an interesting solution - I already talked about the Villy lamp ( habr.com/ru/company/lamptest/blog/410675) (by the way, now Villy has all luminaires with CRI> 90).
In addition to a variety of shapes and colors, Combo luminaires provide high-quality light, similar in its properties to the light of traditional halogen incandescent lamps. The manufacturer gives a 3-year warranty, but most likely these lamps will work much longer. In fact, these are professional fixtures for home use.
