Re: [APD] Off Topic: LED lights

I believe Harry Martin wrote this email section below:

There will be lots of heat!

Nice idea but it may get covered with algae and minerals!
And it'll heat up my tank.

Have people interested in this subject looked at the OLED site?


It has current state of the art OLED news and their videos of a OLED light 
changing colour is cute and full of possibilities!
See http://www.youtube.com/watch?v=uZfrFX36Hkc


These small Tvs are only 5mm thick and the large TV is 10mm!

Philips said this last year:
Philips and Novaled reached a new record for the power efficiency of a white 
OLED, obtaining 32 lm/W with colour coordinates of 0,47/0,45 and a CRI of 88 
at a brightness of 1000 cd/m2. That same device structure thereby 
simultaneously shows a lifetime of more than 20000 hours which is a major 
achievement for a future commercialization of the OLED technology for 
lighting applications.

So people that know these things can tell us if this is good or not! ;-)

Seems to be a OLED lighting project.
