I didn't sweat the details. In this case, good enough is good enough. It could be 600 watts too, but that's more than $40 total. I attach these to $20 mic stands. I just have to find better bulbs with higher CRI, which will also blow the $40 barrier.
I used my Canon SD750 for time lapse and stills, and Vegas Pro 8.0 to edit. Badly.
The music is an old 4-track experiment I dug up.
