LEDinside:Luminous Flux is Key to LED Light Bulbs'Replacement of 40W Incandescent Light Bulbs
Currently descriptions of many LED light bulbs on the market indicate that they are able to replace the 40W incandescent light bulbs,but are they really able to replace incandescent light bulbs in terms of luminous flux?Based on the comparative survey of LEDinside,luminous flux is a key factor.
The luminous efficacy of traditional light sources like incandescent bulbs is approximately 11-12 l/W.In other words,to truly replace a 40W incandescent light bulb,the luminous flux ought to reach at least 450lm.
