Thread: Compact fluorescent backlight

I tried it. I used 6 850lumen (13w) compact fluros. It got too hot, even with a 120mm fan blowing into the lightbox.

1) Aside from the cooling issue, did it effectively light the screen?

2) What exactly do you mean by "too hot". Did it damage your LCD?

Thanks,

Gregory

It was bright, I'd say about twice as bright as the normal backlight. By too hot I mean that the box was so hot i couldn't comfortably hold my hand on it.

floresent lamps are way to inefficent, & will make a whole lot more heat than the same amount of light from ccfl's.. why not use ccfl's, there not very expensive really or hard to get.... the side benifit of being able to dim them will be another huge plus... I don't get why you'd rather use the wrong thing for the aplication when the right thing isn't any harder really?

5000k is more of a bluish white isnt it?

I think the CCFL is a better way to go. They are much more available and manage temperature much better.

Go with CCFL, or LED's. Those're the best options.. and neither is very expensive.

arent LEDS directional though? so wouldnt you get "spotting" unlike an even glow with a ccfl tube?

Short answer: No.
