While it seems to be kind of crude, I currently like adding simple twisty CFL bulbs to the canopies I retrofit. With the switch to LED, I'm finding the CFL real cheap and use simple bulbholders without need for ballasts, etc. With the cheap price, I just add far more bulbs until I get plenty. While the light is not used terribly efficiently as it tends to splatter in all directions, I like the overall economy due to the lack of expense upfront. Also I came into the game running incandescent so any type CFL seems cheaper?
