There are no particular "brands", just a lot of different methods of doing it with standard LED
bulbs. There are a lot of threads on this in the DIY forum. Do a search with "LED
" and DIY Forum and you'll see what I mean.
You can also find some standard "plug and play" setups at Drsfostersmith.com or Bigalsonline.com but those get really expensive if you need a lot of bulbs.
