LED lamps REV
Auchan, OBI, 220 volt, Yulmart, pleer.ru stores sell cheap REV LED lamps. During the existence of the lamptest.ru project, I have already tested 9 lamps of this brand, but in order to finally deal with them, I bought 10 REV lamps in Auchan, which I did not get to me before, and tested them.
I measured the lamp parameters using the Viso LightSpion , UPRtek MR350D and Robiton PM2 instruments . The first ten lamps are the ones I bought in Auchan (they are on the title photo), the other nine are those that were tested before.
The worst is the high level of pulsation in 9 of 19 lamps. The light of such lamps can lead to eye fatigue and general fatigue. Such lamps can not be used in residential areas.
')
On the boxes of all REV lamps it is indicated that the CRI RA color rendering index is> 80. This is a lie. In fact, only in three out of nineteen lamps it is more than 80, in the remaining sixteen lamps it lies in the range of 72.9-77.7.
According to GOST R 54815-2011, the measured initial luminous flux of an LED lamp must be at least 90% of the nominal luminous flux. Of the 19 lamps tested for luminous flux (in fact, this is the amount of light that the lamp gives) only 2 lamps correspond to GOST, and the rest give only 64-88% of the promise.
Good can recognize only one lamp out of nineteen. This is REV-A60-8.5W-230V-2700K-E27 for 195 rubles. It shines like a 60-watt incandescent lamp (although the equivalent of 70 W was promised), it has a decent CRI = 85 and there is no pulsation of the light.
Another filament lamp REV-FA60-7W-230V-2700K-E27 for 211 rubles has a good CRI = 81.9, it has almost no pulsation of light, but it shines like a 55-watt incandescent lamp with the promised 70 watts.
All other lamps either have a high pulsation of light, or a low CRI, or all together.
Only three out of nineteen lamps can operate with switches that have an indicator. The others flash or faint when the switch is off.
The manufacturer specifies a warranty period for all lamps for 2 years and most likely during this period it will be possible to change them or return the money in most stores.
Perhaps someone will say: - What did you want from cheap lamps? I will answer that I would like them to honestly indicate the parameters, besides I am sure that it is 100% unacceptable to produce and sell lamps with a pulsation.
