Yes, they all use phosphor. The only method I know of to create "White" light without a phosphor coating is using three chips: Red, Green, and Blue, for example. At the moment, the efficiency of RGB LED's is pretty low due to something known as "the Green hole" which refers to the horrid efficiency of Green LED's. Many engineers are doing all they can to close the gap between Green LED's and other colors. Increasing the CRI of LED light sources holds a lot of hope for growing, imo.Hey BS
Does this coated with phosphor of the white LED's only apply to Strip Led's or all LED's regardless if they are of the strip type ?
What I mean is..Say I was to buy some 3w white ( WW NW CW ) CREE led's for my DIY project are they also coated with this phosphor ?
Stolen from another forum:
LED nerds talk about some pretty cool things, imo.The holy grail of LED lighting has been always to get white light by mixing pure color LEDs, not getting it by phosphor mixing. But the "green hole" has prevented it for reality in practical lighting applications.If you check the current roadmaps, you can see how many effort is being done at developing efficient green LEDs and improving amber-orange ones.
