Hello
and Welcome To BYC! The Ecoglows are more like a mother hen, the chicks come and go underneath them a lot compared to what they seem to do with a heat light, you just raise the Ecoglows legs as the chicks grow... it should work fine outside at 70*, they say not to use it under 50* because it can't heat enough (I never used one outside where the temp varied that much). Yes, you should have a regular light on to see by during daylight hours in a dark room if you are using an Ecoglow since the chicks won't eat etc in the dark.
