I just wanted to share a tip I haven't seen mentioned on the board... This process produces a great effect, and it's simple.
I like to use rope light to uplight my tombstones. Quick, easy, 1 plug gives you up to 100 feet of nice light. The thing is, rope light glows along it's entire length and diameter.
To control the light (aiming and/or hiding) I use SPLIT WIRE LOOM.
I put the rope light into the split loom, and where I want light, I just cut back some of the wire loom. Pop a couple short stakes into the gound to hold the ropelight in place and POOF! Quick, easy, effective tombstone uplighting. If you need a little extra brightness, just put some tinfoil in the loom with the ropelight, and cut that back with the loom where needed.
I use about 200 ft total (1x 100' & 2x 50' and that lights all our tombstones. I'll post pics as the setup progresses.
