I replaced all of my lights with the Starlights LED's
I found that replacing the incandescent bulbs with LED bulbs was NOT cheap!
I was able to replace all my single and double light fixtures with the Starlights 3002 and 3003 lights AND add photo cell (auto on/off at dark), dimmer and Motion to fixtures I wanted for about $200 total for 16 fixtures.
