[FLINTUS]

A discussion on another forum has made me curious about this. Andy Highfield has yet again presented his theory on heat lamps being too concentrated in their beam, and as a result unnaturally heating the carapace. The theory is that this extreme, constant humidity compensates for this. I have to say, he has presented some very good evidence for this.
Anyway, I am not trying to start a debate on the merits of heat bulbs etc., what I am trying to know is what bulbs people use which have a broader beam? Or other heating options which seem to work? Just interested.
