Thats what i use (the one satanic said, and Icy linked) Works perfect for my heat light (to raise ambient), and is easy to use. Only thing is if you get that model, the brighter the LED is the less electricity to the heating unit, and vise versa, took me awhile to figure out with a CHE as they have no light.
If you want to find it locally They are found in a lighting isle in Home depot, in a section with a few different models, it cost me $12. It should be near the lamps,

You should be able to use the product number on the link to find it locally at Home depot if you dont want it shipped.
