Good heavens, I hope your shed is fireproof! It looks as though that Palight is going to incinerate it. You're right about there not being much spill on the SK-36. For a pure thrower though it looks pretty good. I think it would embarrass the SK-68 if you back it out to 100yds, not sure about the Aurora though....that one looks pretty decent as well :) Nice collection of throwers and thanks for the beamshots.
As a guess I'd say its output would be close to a good 100w halogen headlight.......just more concentrated. I've compared it directly to a 12v 50w halogen spotlight and the halogen looked like a candle in comparison.
The palight boasts a 'zoomable' beam, but in reality the zoom simply creates an enormous doughnut on the 'in' setting, and a microscopic hot-spot on the 'out' setting.
