![]() ![]() 2700K is generally considered the maximum limit you should select, but even then, there are not enough to studies to know the long term effects of LED light beams. The result is that the higher the CCT you select, the more risk to your health. Never use an LED device where the bare diode is visible to your eye.įigure 2 – 4000K LED Spectral Power Distribution Note that all the lamps are diffused with a lamp shade, which is a must for eye safety. However, we must be very careful with understanding the true nature of what this means. While CCT is not actually a legitimate way to measure the spectral power distribution of LED light, the industry uses this CCT value. ![]() However, even at 300 lumen and 2200K color temperature, the non-uniform bullet shape is still foreign to human nerves and may be causing sickness.įlicker is not listed on the light bulb packaging, and therefore there is almost no way to know how your nervous system will react to the subsensory flicker created by the LED electronics.įigure 1 illustrates approximate Correlated Color Temperature for LED lights. A 300 lumen 2200 Kelvin is much less toxic than a 1600 lumen 5000 Kelvin LED. The amber light is also more appropriate for lighting used before sleep. LED bulbs that have an amber color are safer because there is less blue wavelength light. We believe that any LED light bulb that exceeds 2700 Kelvin is dangerous for everyone and the higher the lumens, the higher the danger. ![]() Since LEDs do not light a room uniformly, LED light bulbs are not a viable choice for indoor illumination. We recommend incandescent light bulbs, not LEDs, because the long term effects of LED visible radiation is lacking rigorous study. ![]()
