What Wattage UVB would you recommend for a Jacksons Chameleon

[Kamran_k]

So I was wondering which UVB should I get I got a 24w Linear one in the mail but it came in broken so I was wondering if that'll suffice or should I get a lower or higher wattage I already have ordered a light fixture that someone recommended and its 2 feet long.

Currently I have a 13 w UVB but I didn't know much about chameleon husbandry at the time and got the double dome I have since educated myself and purchased better lighting.

His Heat bulb is a 45w DuraMax Indoor Flood R20 from home depot I purchased yesterday previously I was using a Zoo Med 60 W blue light but the enclosure would get too hot so someone on here recommended the the light I have now, he's only a Juvenile and I heard mid 80s is too hot of a basking temp for a Cham that young now the basking temp is around 77-80 and ambient is mid 70s during the day and mid 60s at night
