Cold cathode tubes to light a Marquee?

mamemarquees.com, opt for the premium backlit stuff
vrf:
yeah, I may have to go with mamemarquees, although my job will be a fraction of the smallest size/price on his site. Thanks!

Both myself and several people I know have had those cheap inverters with CCFLs blow up, in some cases with spectacular results, in mine just a bad smell and a hole melted in the side of it.
Ive decided that they are not worth the risk.
With white leds being as good and as cheap as they are now, thats a much better option IMO.
vrf:
richms... how would you get a nice light panel from LEDs? And how would you power it?
richms:
I would get some nice wide angle ones rather then the insanley high mcd but useless viewing angle ones that seem to be all too common.
I would then sand the end to make it more diffuse and place them on a white background.
Probarbly would need 10 or so across a normal sized marque.
Run off 12 v with the appropriate resistor, maybe a higher value one to reduce the brightness a bit if it ends up too much.
otherwise could try the leds at the front aiming onto the white back of the marque box.
