Go to petsmarts website- click on reptiles- click on heating and lighting I think it's yellow - it will say digital probe- sorry I am on my phone and not desk top- you need to get a UVB- a tube fixture w/ a reflector-- www.pangeareptiles.com has a 24" fixture for $32--- it will hold a reptisun 10.0 T 5 or a T 8 bulb--- how big is your tank? 20 gallon? I would get the T 8 for now-- but you need to get this right away and get your basking temps correct
