Sign lighting

[brian]

I'm doing a billboard frame for a 10' x 20'long sign.
How much lighting would be needed for this size of sign.
Would a single light source be good or two evenly spaced smaller lights be better.

front lit or back? I assume front. 20 ft is big, use at least 2 but it depends on your wattage

I know this is an old post but I thought I would post the type of sign lighting lamps that we stock. We currently stock Gooseneck and Straight Arm lamps in eight different colors and with three different extension lengths. these are great for Signs, Awnings, and general lighting.
