Mostly use Ott lamps - have a few different models. Got most of them from swapmeets (flea markets). You can get "day light" bulb replacements from McMaster Carr.
I use a 13 watt Ott light for my pouring and tying. I found a replacement bulb at Harbor Freight that I think will work for under $3. I'll find out when a bulb burns out. Bought my two on ebay new for around $25, been a few years though.
