I continue to torment you with decorative LED lamps. :)
Today we are studying Feron AL5000 28935 60W for 3960 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. There is 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 60 W;
• luminous flux 5000 lm;
• equivalent to a 4x100 W incandescent lamp;
• color temperature 3000-6500K.
Color rendering index is not specified.
The set includes a remote control with 9 buttons. The lamp came to me without a remote control, so I bring a photo from the box.
The purpose of the remote control buttons in the picture from the manufacturer's website.
The state of the luminaire (color and brightness) is remembered when disconnected from the network and then turned on.
Modes can be selected not only with the remote control, but also with a conventional light switch. If you turn off and turn on the light, the lamp switches three modes in a circle: warm-white-cold at maximum brightness.
Due to the lack of a remote control, I was not able to measure the parameters of the lamp at different brightness modes and colors, but this, as it turned out, does not make much sense - the lamp uses LEDs with a low index color rendering.
Maximum brightness is achieved in neutral light mode when both the "warm" and "cold" LEDs are on.
Luminous flux ~ 5600 lm, power 62 W, color temperature ~ 4200 K, CRI, alas, 76.2, ripple coefficient 0.1%.
Warm light mode.
Luminous flux ~ 4400 lm, power 62 W, color temperature ~ 3000 K, CRI 72.
Cold light mode.
Luminous flux ~ 4550 lm, power 62 W, color temperature 6500 K, CRI 74.
The luminaire does not create any interference with radio broadcasting.
The LEDs are mounted on metal plates for good heat dissipation.
The luminaire is fastened to the ceiling using three holes. The plafond can be easily removed by turning.
The measured parameters of the luminaire are close to those stated. Unlike many other similar lamps, the brightness does not change very much when the color temperature changes - a little more than 20%. There is no light ripple.
The main problem with this lamp is its low color rendering index. Most likely the manufacturer saved less than 1% of the total cost on this, but ruined everything with it. And it could be a good lamp.
A review of two General decorative ceiling lamps will be in a week or two, 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 figure out which ones are good and which are not so good.
