The possible blue light hazards in LEDs on  the eyes have become a hot global topic. The expanding application field for LED lighting has raised consumer awareness towards the possible risks of blue LEDs. In order to clarify the consumers misgivings towards LED lighting products, the China National Lighting Fitting Quality Supervision Testing Center (CLTC) has released a report addressing the dangers of blue lights in LEDs. The CLTC advises that single LED package components with 1W power must strengthen structural protection measures and that color temperature for indoor lighting must not surpass 4000K.
