Yeah I use one in the coop too when it gets below freezing. I think a 100w ceramic is safer as it isn't likely to start a fire if a feather flies against. it. I don't like having chicks or adults under a light all night, it is supposed to get DARK at night. $4 is a darn good price! I think I paid about $18 for the one I have (though reptile stuff is always more expensive).
