I have solar powered flood lights, look like small flouresent, but I think they are large "LED's". they run on four (4) 1 1/2 volt rechargable batterys. If you can get Awning lights that are LED's and they will run on 6 volts just look for the "Floods" on sale in the "north" country (late fall before winter), places like Home Depot/ Lowe's sale price them instead off holding them until spring. Got mine last fall for $4 each, complete with solar charger. I already had 2 solar lights with 1 Led each, for 4 years, (mounted in a tomato juice can with rocks and holes for drainage). The batteries went dead, $5.95 for set of 4, so I bought the "Floods" just for the batteries, and ended up using them anyway!
