LED lamps Feron
Many readers and visitors to the site lamptest.ru asked me to test the super-cheap Feron LED lamps, which retail for 114-149 rubles. I tried several times to contact Feron and asked for samples for testing, but I never received a response. And then I just bought 7 lamps, using the money collected through fundraising on the site.
I tried to cover the range of lamps as much as possible, so I ordered a pair of pears, a pair of candles, a G45 bulb, a spot GU10 and a filament candle (there were no pears on sale) from the official Feron online store.
')
The lamps that were brought to me were made quite recently: on all lamps, except the filament candle, the date is 06.16, on the candle - 10.15.
I will begin with the results of my measurements obtained using the Viso LightSpion , UPRtek MR350D, and Robiton PM2 instruments .
The main conclusion that can be made from the measurement results, all the lamps from Feron are DIFFERENT. For some, the color rendering index is quite decent, for others it is around 75 and should not be used in living rooms.
I am glad that six of the seven lamps tested have no light pulsation at all and only one lamp has 27%, which is also within the normal range.
In terms of brightness and power, everything is traditional for cheap brands. Luminous flux and power on average make up 75-80% of the declared. This means that buying such lamps, you need to take them with a significant margin for the light flux. If the lamp says "7 W 560 Lm equivalent to 70 W" you need to clearly understand that in reality it will be 5 W, 450 Lm and 50 W equivalent power.
When the filament “candle” with four threads says “5W 530 Lm”, you can be almost sure that the real power is not higher than 4 W (the standard thread has a rated power of 1 W) and the luminous flux is not higher than 400 Lm.
In this case, the power was 3.55 W, and the luminous flux was 350 Lm. This corresponds to the equivalent of a 40 watt incandescent lamp. Surprisingly, the manufacturer indicated exactly this equivalent value - 40 W, while significantly overstating the values ​​of the luminous flux and power.
The manufacturer specifies a warranty period of 2 years for all lamps.
Should I buy cheap Feron lamps? I have no definite answer to this question.
On the one hand, there are good and very cheap lamps: for example, the LB-92 “pear” costs only 149 rubles, it has a decent color rendering index (CRI = 81.5), no light pulsation, it works with switches that have an indicator and replaces 60 with a margin the watt incandescent lamp (although they promised to replace the 100-watt one), and the “ball” of the LB-95 for 144 rubles has an even greater CRI = 83.4, it also has no pulsation, it will successfully replace the 40-watt incandescent lamp (promised 70 W) , but with a switch that has an indicator, it does not work correctly (it glows a little when the switch off).
On the other hand, four of the seven tested lamps have a low CRI and it is better not to use them in residential areas. And what kind of lamps are good and which ones you don’t guess very well: for example, a good LB-92 and a not very good LB-91 look exactly the same.
It seems that the manufacturer orders the lamps at Chinese factories arbitrarily, without prior testing and without paying much attention to the parameters, so with such a “lottery” any lamp can turn out to be good or bad. For example, exactly the same “ball” of the G45 with the E27 base, and not E14, may turn out to be with a low CRI, or maybe with a high one. Lottery.
Even with this approach, there is a danger that lamps with the same names from other batches released earlier may turn out to be completely different.
Buy lamps Feron or not, you decide. But of course good lamps, replacing the 60-watt incandescent lamps, for 149 rubles - this is very, very cheap.
