I was bringing the ducks in from school - and I had my light on top of a box and it fell off and shattered on the floor. I have this other big red light I ordered from the mill and feed place several years ago, but don't know how hot it gets. I have it hanging way up above the brooder, going to stay up and measure the temp and make sure it isn't too hot. It is not a regular light bulb that is red like the other, but more of a heat lamp style....I'm sure I ordered it as a brooder light, but I don't want it to get too hot for them. It gets a lot hotter than the other one I can tell already. I live 300 miles away from the nearest feed store - not like I can run out and buy another one... I should have a supply handy - I can see that now. How does a regular light bulb work??
