deryk, I went the route of buying a whole bunch of LED bulbs that spec'd out not too bad from an eBay seller. I think I paid not much more than $30 for 10, plus they threw in 2 others for free. They were not near as bright as the incandescent bulbs that were in there already. I tried a couple a friend had bought from www.superbrightleds.com
for $15 each, and they were just as good as the originals, or better. These were a wedge type, but they are available in bayonet mount too. I would highly recommend them, regardless of going with solar
, or not.
