AFMA results - Conflicting values

[Steph]

I use three 150 W gooseneck lamps, so I actually use less total wattage. But...remember the inverse square law. My lights are positioned about 12" from the target.

Alright, I'll try to setup something in my garage then with the 500W spotlight reeeally close to the target. I'll post other results and let you know how it went.
