high luminous efficiency, uniform light color.
Optical unit with extremely high luminous efficiency(185,000 lux at 10 m).
LED technology is changing with each passing day, and its luminous efficiency is amazing breakthrough,
Led technology is changing with each passing day, its luminous efficiency is amazing breakthrough,
high luminous efficiency;
high luminous efficiency;
high luminous efficiency and long service life.
Luminous efficiency comparison: incandescent light effect in 10-15lm,
High efficiency: The luminous efficiency of the high power LED wall lamp has exceeded 100 lm/W, and the spectrum of the LED is almost all concentrated in the visible light band.
have better heat dissipation, cooler temperature will let Cree chips keep higher luminous efficiency and longer lifespan.
Adopted import 1W high power LED which luminous efficiency is about 120lm/W and its heat emitting in unit area is small,
The advanced energy saving lamp source is selected, with high luminous efficiency and long life span of 50 thousand hours. The power factor is more than 0.8, the luminous efficiency is high, and the transmittance is good.
high luminous efficiency, good light transmission.
adopt a multi- chip high power high luminous efficiency high show 3030 led lamp bead,
high luminous efficiency, light color uniform and other advantages,
LED is the light source with the highest luminous efficiency so far,
This 25W tube light is super high in luminous efficiency, and with high power factor guaranteed,(>0.80)(different configuration available);
Comparison of luminous efficiency: incandescent, halogen light efficiency of 12-24 lumens/ watt,
LED tube will rise, which will lead to the LED tube luminous efficiency is reduced, shortened life.
so the theoretical limit of the luminous efficiency of the PM-OLED device is only 25%.
