The current state of energy efficiency and light quality of led products

The article presents the results of energy efficiency study and light quality LED illuminators (lamps) for general lighting, in particular colorimetric parameters, flux modulation photobiological safety. It is shown that two-base lamps with G13 base luminaires outdoor lighting have achieved class A++. E27 indoor fixtures diffusers a output 25–35% lower correspond to classes A+, A, B. Correlated color temperature (FTA) mainly range 3000–4500 K, total rendering index Ra – 71–86 units. deviation chromaticity from nominal values can reach 7+ degrees McAdam ellipses (7+ standard deviations SDCM comparison color). angular non-uniformity diffuse does not exceed 3 SDCM, without lens optics - SDCM.
 safe level flicker visibility stroboscopic effect. In frequency up 80 Hz, level, which observed probability 50% than incandescent power 60 watts. 3000 depth corresponds create adverse biological effects.
 entering market do parameters insignificant risk danger group blue RG1. Lamps using belong RG0 (no risk).
 Conclusions are made on lamps.
