This was given as a gift, so i believe it can be purchased where other grill accessories are sold. The grill light has 10 super bright white LED's, a flexible neck, and an oversize clip that fits most 2" thick surfaces. They even include 4 AA batteries for the light. The stainless steel light should be postioned on either side of your grill, unless you have the sideburner type. Thus you should place it on the opposite side of the burner. Keep away from fire or cooking surface. When attaching to your grill be careful of the tension spring on the clip. As with anything around a fire, use extra care.
I'm not sure why anyone would buy one of these, unless you cook at night and don't have a light. Also they recommend it be removed from your grill and taken in, while not in use. The clip is a pain to put on and off. They also recommend removing batteries if not used within a two week period. I found this to be more of a nuisance than helpful-was a gift so we said thank you .
