Decorative ceiling light Leek Celebrity

A lot of LED lights have appeared in stores, which are controlled by the remote control and can change the brightness and color temperature of the light. I got the opportunity to test five of these fixtures of three manufacturers.

Let's start with Leek LE 061202-013 CLL Celebrity for 5,000 rubles.

The manufacturer indicates the following parameters:

• power is 120 W;
• luminous flux 5400-8500 lm;
• color temperature 3000-6500K;
• color rendering index, Ra ⩾80.

The kit comes with a remote control with 13 buttons.

Separate buttons include three color modes, the mode of minimum brightness of white light "night", the mode of 50% white light. There is a timer off button. The ring buttons decrease and increase the brightness and change the color temperature of the light. The central button does nothing.

When turned off from the network, the lamp remembers the state and turns on in the same mode as it was when turned off.

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 will change the color temperature (three modes in a circle).

The luminaire uses LEDs with a warm light of 2700K and a cold light of 6500K, but they never burn separately - in all modes, the light of the two groups of LEDs is mixed.

In the “warm” mode, the color temperature is 3456K, the lamp consumes 52.6 W and gives 2704 lm.

In the brightest "neutral" mode, the color temperature is 4089K, the lamp consumes 103 W and gives 5274 lm. In the "50% brightness" and "night" modes, the color temperature is the same.

In the “coldest" mode, the color temperature is 4813K, the lamp consumes 82.8 W and gives 2777 lm.

At minimum brightness, the lamp gives 332 lm (12% of maximum). It is too high a brightness to use the lamp as a night lamp.

At the maximum brightness, there is practically no light ripple (ripple coefficient 0.3%), at a brightness of 50% the ripple is 16.3%, with a minimum brightness of 27.3%. Visually, such a ripple is invisible, but this is another reason why the lamp should not be used in nightlight mode.

A two-color LED strip without resistors is used as a light source in the lamp. It is glued to the ends of the rings, but there is one problem: the tape bypasses the mounting posts and some LEDs hang in the air and do not cool. We can assume that this is not the best way to affect the life of the lamp.

The lamp is mounted on a metal cross. It is fixed to the ceiling, and the lamp is screwed to it with four screws.

The manufacturer promised a power of 120 W, a luminous flux of 5400-8500 lm and a color temperature of 3000-6500K. The measured luminaire power at 100% brightness is 53-103 W in different color modes, the measured luminous flux in the brightest white neutral light mode was 5274 lm, and in warm and cold light only 2704-2777 lm. Color temperature varies in the range of 3500-4800K.

Most likely, the main mode of operation of this lamp will be the “warmest” mode, because since the designers came up with a two-color solution, I want to use it. But in this mode, the color is not so warm (3500K), the light will be three times less than the promised maximum and for an ordinary room of 15 m² this will not be enough.

It is important to remember that most luminaires with a variable color temperature burn most brightly only in the color mixing mode, when all the LEDs operate at maximum brightness, and in other modes the brightness will be lower, up to 50% of the maximum.

The review of the next decorative ceiling lamp General 800325 GSMCL-Smart25 will be in a week, but now you can see the test results of all five fixtures at Lamptest: lamptest.ru/search/#&shape=Lamp&type2=mod . The results for all modes of each lamp can be viewed by clicking on its model in the table.
