Depends on which type you want. I get my puppy heat lamps from Diamond Edge, as they do the dull emitter bulbs, all heat no light. They last ages but are quite expensive. However, in the runs I use ordinary infra red ones, red coloured, as I think the clear ones are too bright. I have found these cheapest from an online company called LYCO - about £3 per bulb cheaper than our local Agricultural merchants. However, the Agricultuaral places are very cheap for the actual fitments, if it is not just the buld you want.
