UVB light should be minimum 10inches or more away & the length I order should cover 70 percent of the tank and the zoomed heat lamp no real distance just Def not closer than 8inches to him basically till u reach the rite temp. Also he needs a a hideaway to get away form the UVb as needed here’s a pic sample of mine. Also start the UVb light at the hot/basking spot so when they bask they get the UVb.Thank you all! I’ll do my best!
