LED Camelion Lamps
I bought and tested 16 Camelion bulbs of two series. The differences between the series were not as obvious as expected.
It used to be simple: there were Camelion LED Ultra lamps in green boxes with a CRI (Ra) 80+ color rendering index and everything was fine with them (with the exception of some G4 and G9 lamps with 100% ripple) and there was a BasicPower economy series in white boxes with CRI (Ra) 70+. Now the color of green boxes has changed and a large inscription “Meets GOST” has appeared on them, while the packaging indicates GOST R IEC 62560-2011, which regulates only safety requirements, but not technical parameters.
The technical parameters on the white and green boxes are now indicated exactly the same. Even the article numbers of the lamps match.

On all lamps in white boxes, except for one, the color rendering index Ra 82+ is indicated. The LED7-A60 / 830 / E27 lamp box, released in January 2018, shows Ra 77+. Looking ahead, I’ll say that the actual color rendering index of this lamp was 80. But the other two, on the boxes of which are written 82+, unfortunately, turned out to be low - 72 and 74.
Luminous flux, color temperature, and color rendering index were measured using a two-meter integrating sphere and an Instrument Systems CAS 140 CT spectrometer, power consumption and power factor with Robiton PM-2, pulsation with Uprtek MK350D. The minimum operating voltage, at which the luminous flux was reduced by no more than 5% of the nominal, was measured using the Lamptest-1 instrument, the Stabil Instab 500 stabilizer, and the Suntek TDGC2-0.5 LATR. Before measurements, to stabilize the parameters of the lamp, they were heated for half an hour.
All lamps do not have ripple and this is very good.
Thanks to the pulse driver, all the lamps work at a significant decrease in voltage, without reducing the brightness (minimum voltage 103-137 V).
The measured luminous flux (the amount of light that the lamp gives) for different lamps amounted to 82-111% of the specified, while I did not notice any connection between the luminous flux declared with a series of lamps.
The actual equivalent power (corresponding to the power of an incandescent lamp) for most lamps is slightly lower than indicated.
Unfortunately, two lamps in a white package - a LED8-G45 / 830 / E14 bulb and LED8-C35 / 830 / E14 candles, released in March 2018, the measured color rendering index turned out to be low - 72 and 74, even though the packaging of these lamps says "82+".
With lamps with an indicator, all lamps work (only one, LED7-A60 / 830 / E27, manufactured in January 2018, burns weakly when the switch is turned off).
On the packaging of all lamps, a power factor (PF) of more than 0.7 is indicated. Apparently this is done to meet the difficult requirements of Decree No. 1356 of the Government of Russia. The measured power factor was from 0.49 to 0.58. There are no miracles. However, for home use this does not matter.
All lamps have a 2 year warranty.
After the publication of the article, a representative of the brand contacted me and said that the BasicPower lamps in white boxes are no longer manufactured, although their remains are still on sale. Only Camelion LED Ultra lamps in mint-green packages are currently available, and they are worth buying.
