The 160 Watt will cook the Russian. I use a 75 Watt and it is 14" away. It still heats up the area to around 95 degrees. I will be upgrading soon to 100 Watt.
I have a zoo med 75 Watt and a 100 Watt UVB light. I have heard good things about the Zoo Med Powersun. Good luck! I'm new at Russian tortoises too!
Yes. It has heat and UVB all in one.. A 160 watt is a lot. Maybe get a 100 watt. It won't get as hot so you won't have to have it so high up.
When it comes to keeping the light high, what is the preferred way to do this? Clamping onto the tank, hanging from the ceiling, or wall?
If anyone has photos of their lights hanging/not sitting on top of the tank I would love to see!
