I have a reptisun 10.0 HO bulb in a reflector in my 4x2x2 tank and it's about 12 inches over the basking spot (inside the tank.) I attached a picture for reference, just wondering if it's too close since it is a high output bulb and if I should move it somehow. Thanks!
12-15 inches from the basking spot is the preferred distance from the reptisun 10.0 HO. So you're within range. Plus, it looks like there are areas where your dragon can get a bit closer or further from the bulb, which is good.
