Brooding outdoors with a Brinsea EcoGlow?

[buckbye]

The fine print of the instructions of the Brinsea EcoGlow brooders says not to use the unit in a room where the nighttime temp drops below 50F (10C). Is this really mandatory? Has anyone here broken this "rule?" What was the result? And, more specifically, has anyone used a Brinsea EcoGlow in an outdoor brooder (or inside an unheated outbuilding such as a barn or shed) in winter? What happened? If baby chicks can survive being outdoors in winter with a broody, wouldn't the EcoGlow, which is designed to basically be an electric hen, suffice? Thanks for any help!

I'm not sure this is the answer but perhaps the heat generated is insufficient to overcome say a 30 or 40 degree building.
A hen is going to put out 103ô no matter what the ambient temperature is.
When I brood outside, I use 1 or more ceramic emitters, depending on ambient with either a hover brooder or a lamp guard. So the space around it is over 100 and a lot of cool space.
