What many were waiting for has come true - LED lamps with high-quality light, good electronics, honest parameters and high reliability have appeared on the market. But it didn't come cheap.
Lamps Navigator Supervision have two significant differences from most lamps on the market:
• Super high color rendering CRI(Ra)>97 flat spectrum and no "blue peak". Lamps use LEDs Bridgelux Thrive.
• Gentle mode of operation of the LEDs, due to which the lamp heats up less and lasts longer.
The lamps are built on impulse (IC) drivers, due to which they operate in a wide range of supply voltages (130-260 V) without changing the brightness, while there is no light pulsation.
The manufacturer gives a 5-year warranty on these lamps.
In total, there are eight lamps in the Supervision series - four types ("pear" 810 lm / 900 lm, "ball" E27 and "candle" E14 540/600 lm, as well as spot GU5.3 430/480 lm) in two color temperatures - with warm light 2700K and with neutral 4000K.
As of March 29, 22, lamps cost from 531 to 667 rubles apiece, they can be bought to Ozone And Wildberries.
I tested two copies of all lamps and got the following results.
Lamps with warm light.
Lamps with neutral light.
The "warm" spot has a color temperature of 3000K, but in fact it turned out to be the same as the rest of the lamps - about 2700K.
The rest of the measured parameters correspond to the declared ones, and the luminous flux of many lamps is higher than the declared one. The lamp boxes indicate the operating voltage range of 176-264 V, in fact, the lamps work fine on lower voltages (the voltage at which the luminous flux decreased by 5% is indicated in the column of the table "Umin"). All lamps work correctly with switches that have an indicator.
The spectrum of lamps of warm and neutral light (for example, "candles").
Even lamps with neutral light have practically no "blue peak" (scientists say that high intensity blue color in conventional LED lamps with neutral and cold light leads to degradation of the retina and deterioration vision). The spectrum is much smoother and closer to the sun, compared to the spectrum of conventional LED lamps, there is no dip in the turquoise part of the spectrum.
The design of all lamps is two-board. There are 18 LEDs in the "pear", 12 in the "ball" and spot, and 14 in the "candle".
I compared the temperature of the Navigator Supervision lamps with the temperature of conventional lamps with the same light output.
The shells of the pear, ball, candle and spot heated up to 54, 59, 57 and 55 °C, respectively.
Conventional lamps have much higher temperatures - 73, 68, 70 and 71 ° C, respectively.
The thermal imager cannot accurately measure the temperature of the LEDs, but you can compare the readings "in parrots". Pear, ball, candle Navigator Supervision - 62, 63, 65.
Ordinary lamps - 83, 81, 70.
Of course, Navigator Supervision lamps are not for those who buy cheap lamps. But for those who want to get the highest quality and safest lighting, 600 rubles for a light bulb is not such a terrible price.

Peace for everyone!
