The wattage of the light bulb and the computer. If you think about it, a home computer power supply is rated at around 300-500 watts. Now the computer isn't probably using all this , but go at least half...that's at least 150 watts for the CPU, now you need to add in the monitor. If it's a big 19-22 inch, then there's a 100 or so watts there. So you can see that the whole computer may use between 250 watts min to 400 watts. That would be a flood lamp. Hope this helps.<br><b>References : </b><br> Depends on a couple things really. The wattage of the light bulb and the computer.
