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!

richms:

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.
