December 8, 2015 at 09:43LED lamps from the Leroy Merlin store
A week ago I talked about LED lights from the Auchan store . Let me remind you, I bought 48 lamps in Auchan and Leroy, tested them and returned them to stores .
Today I will talk about 26 lamps from Leroy Merlin.
Only two lamps turned out to be bad - a 4-watt lamp from an unnamed series of products by Leroy Merlin (manufacturer is indicated in the manual - Bellight) and spot Wolta LED Simple. Both lamps have a very high level of light pulsation - 102% and 69%. How ripple can be more than 100% read here . In addition, an unnamed lamp gives only 58% of the declared luminous flux.
Measurement results with Viso LightSpion and Lupine .
Four lamps give the luminous flux more than promised, another four give 91-95% of the declared luminous flux. Thus, of the 26 lamps tested, only eight comply with the requirements of GOST R 54815-2011 , in accordance with which the measured initial luminous flux of an LED lamp must be at least 90% of the nominal luminous flux. Nevertheless, 21 out of 24 lamps (we do not consider two bad ones) give an equivalent luminous flux such as indicated on the package or even more (for example, the equivalent is 60 W, and the lamp shines like a 75 W incandescent lamp).
A few words about the lamps of each of the tested brands.
Osram.
Two lamps tested. There is no ripple of light. CRI is quite high - 83.3-83.4. A 10-watt lamp shines like an 80-watt incandescent lamp, although the manufacturer indicates the equivalent of 60 watts. A 6-watt bulb shines like a 50-watt incandescent lamp, although the equivalent of 40 watts is promised. Osram - the only lamps tested to give a warm light of 2700K - exactly the same as incandescent lamps. Both lamps do not work with switches that have an indicator (flash in the off state) and this is their only drawback.
Lexman
Tested ten lamps. Lexman is Leroy Merlin's own brand. Seven lamps have no pulsation at all, and three have 29-32%. Such pulsation is not visible to the eye. All lamps have a fairly high CRI - 82.1-83.5. Four lamps work correctly with switches that have an indicator (these are “pears” 10 W, two different 7 W and spot GU10 5.5 W). The measured luminous flux amounted to 75-106% of the declared, with all the lamps shining equivalently, as stated or even brighter. Good inexpensive lamps, which, moreover, can be easily exchanged under warranty if something happens to them. Six lamps have a 5-year warranty, and four have a two-year warranty.
Uniel and Volpe.
Five lamps tested. The Volpe brand belongs to Uniel, so I did not stand out separately.
All lamps do not have light pulsation and they have a rather high CRI of 83.1-85.1. All lamps work correctly with switches that have an indicator. Two candle lamps allow you to adjust the brightness and dimmable to almost zero (minimum brightness 0.7% of maximum).
Three lamps on LED threads. As far as I know, all threads have a power of 1 watts. There are only 4 threads in an 8-watt lamp and its real power is 5.6 watts. Experts say that the threads in this case are “dispersed” - each operates at a power of 1.4 W, instead of its own 1 W. It is not known how long such a lamp will last, but the manufacturer gives a 3-year warranty. Of course, the lamp gives much less light than stated - only 72% of the promised 800 Lm. The lamp shines like a 60-watt, and the equivalent of 75 watts is declared. 6-watt lamps (frosted bulb and candle) have a real power of 3.9 watts and shine like honest 4-watt lamps on LED threads: the bulb gives 401 Lm (500 promised) and replaces the 45-watt incandescent lamp (50 promised). The candle gives 476 Lm (also promised 500) and replaces the 55-watt incandescent lamp (and promised only 50).
A 6-watt dimmable candle gives only 75% of the promised light output and is able to replace a 45-watt incandescent lamp, and not a 60-watt, as promised. The 6-watt dimmable Volpe candle gives 81% of the promised light output and also replaces the 45-watt incandescent lamp (and only 40 were promised).
Wolta.
Eight lamps tested.
As I wrote in a previous review, Wolta has two series of lamps - ordinary in orange boxes and simple in white. All the orange that I tested were good. Many whites unfortunately have an unacceptable level of light pulsation. In this test, this turned out to be a 5-watt GU10 lamp with a 69% very uncomfortable ripple for the eyes. At the same time, another lamp from this series - 3-watt GU10 has only 25% ripple, while the remaining eight lamps do not have it at all. CRI turned out to be at a good level of 83-83.6 in six lamps, and in two (and the first of the usual, “orange” series) - 72.7 and 77.7. Six out of eight lamps work correctly with switches that have an indicator. Although the lamps have a luminous flux of 75-95% of the declared, everything is fair by the equivalent, and five lamps even shine brighter than promised.
As you can see, the lamps in Leroy Merlin were much better than in Auchan. I can safely recommend buying a lamp of my own brand of the store - Lexman, Uniel and Volpe lamps (just do not forget that one thread is 1 W, and everything else is “crafty”), most Wolta lamps.
All parameters of the tested lamps and Viso reports, including the spectra of the lamps, as well as all other results of my tests of LED lamps, see lamptest.ru .
