Crested gecko heat lamp req

so ik I ask lots of questions, and Im sorry, lol. but I have a 18x18x24 tall terrarium, and i’d like to know what heat bulb is good for that size tank for my crestie, zeus

It would depend on your specific situation, how much you need to raise the temp etc. But lots of people use nano-halogens, with a dimming thermostat.

i have an 18x18x24 tank, js wondering what kind of lamp i need, im currently housing my crestie in his tank, and am using a 13 watt uvb bulb and a 25 watt basking bulb
