I continue to study decorative LED lamps.
Today I am testing a controlled LED lamp General Lumino 02 130W (GSMCL-Smart25) for 5165 rubles.
The lamp uses LEDs with two color temperatures, mixing their light in different proportions allows you to change the color temperature of the light, in addition, the light of two colors is used as a design decision. There is also a brightness control. The luminaire is controlled by the remote control, in addition, the modes are switched by a conventional switch.
The manufacturer indicates the following parameters:
• power 130 W;
• luminous flux 3180 lm;
• brightness control 10-100%;
• color temperature 3000, 4000, 6000K;
• color rendering index, Ra 80.
The luminaire uses LEDs with warm and cold light, but they never light up separately - in all modes, the light of the two groups of LEDs is mixed.
The set includes a remote control with 12 buttons.
The button in the center of the ring turns on the white light. In this mode, all LEDs are lit at maximum brightness and the color temperature is 4300 K. The lamp consumes 97.6 W, gives 5032 lm,
The month and 50% buttons turn on the same white light at 6% and 40% brightness (measured values).
Button A turns on the warmest light mode: 3558 K, 49.3 W, 2498 lm.
Button B turns on the coldest light mode: 5168 K, 50.5 W, 2669 lm.
The circular arrow key toggles the three modes described above.
The K- and K + buttons change the color temperature of the light (6 steps).
Buttons - and + change brightness (also 6 steps).
Any color temperature adjustment or color mode switching will always reset the brightness to 100%.
When you turn off the light with a switch on the wall, the mode is not remembered, the lamp is always turned on in mode "B" with the coldest light.
Modes can be selected not only with the remote control, but also with a conventional light switch. If you turn off and on the light, the lamp switches in a circle four modes: B - A - White - 50%.
At minimum brightness, the lamp gives 159 lm (6% of maximum). The brightness is too high to be used as a night light.
At maximum brightness, there is practically no light ripple (ripple coefficient 0.2%), at minimum brightness, the ripple coefficient is 6.5%.
Color rendering index in all modes is above 80, so this luminaire can be used to illuminate residential premises.
The luminaire does not create any interference with radio broadcasting.
The luminaire uses two types of light sources. In a large circle are semicircular aluminum strips with LEDs.
In the center, LED strips without resistors are glued to frosted glass diffusers.
The luminaire is mounted on a metal crosspiece. It is fixed to the ceiling and the lamp is screwed to it with four screws.
The manufacturer promised a power of 130 W, a luminous flux of 3180 lm and a color temperature of 3000-6000K, but if you divide the promised lumens per watt you get a very strange figure of 24.5 lm / W, not at all typical for LED lighting.
The measured power of the luminaire at 100% brightness is 49.3-97.6 W in different color modes, measured by the light the flux in the brightest white neutral light mode was 5030 lm, and in warm and cold light modes, only 2500-2670 lm. Color temperature ranges from 3560-5170K.
Most likely, the main operating mode of this lamp will be the "warmest" mode "A", because since the designers have come up with a two-color solution, I want to use it. But in this mode, the color is not so warm (3560K), and the light for a normal room of 15 m² may not be enough. The light is uncomfortable, part of the ceiling remains dark, in the corners of the room it is also dark. An ordinary chandelier with five bulbs of 400 lumens visually gives more light and more pleasant light.
A review of the next decorative ceiling lamp Feron AL5000 will be in a week, but now you can see the results of testing all five lamps at Lamptest: lamptest.ru/search/#&shape=Lamp&type2=mod. Results for all modes of each luminaire can be viewed by clicking on its model in the table.

The main topic of my blog is technology in human life. I write reviews, share experiences, talk about all sorts of interesting things. My second project - lamptest.ru. I test LED bulbs and help me figure out which ones are good and which are not.
