Although the basking light claims it is infrared, it does give off a great deal of white light. It came in the starter kit that we bought from Petco.
Even with the heat sources we have, the heat hasn't been getting higher than 102* or so, and seems to stay around 97*-99*. The basking point stays a few degrees higher, but I haven't seen it get over 105*. The cool side has been around 85*. We have two digital thermometers, one on the hot side and one on the cool side, and we also have an infrared thermometer 'gun'.
I have some mealworms on order, and they will be shipped on Saturday (which means they'll show up end of next week, I think) and the crickets started out as pinheads, but are now a bit larger but I've been careful to not give him ones that are bigger than the space between his eyes.
For supplements, I've been dusting the crickets with calcium powder and we have a vitamin powder that I've dusted them with once or twice. Since he hasn't eaten any since the first day, I don't think he's gotten any of this.
He is still passing stool, at least once a day.
