Hello misty,
These bulbs are similar to household bulbs. You can find a fixture at any home improvement store. Just make sure the heat sink is not covered. Like this..
Rapid LED recommends 1 per 18x18. Three over a 48" would suffice for most but you will need 4 if you want to grow everything under the sun.
thanks,
Ray
