Hmm, I was just testing out the P60 and P61 lamps... I'm kind of disappointed in the P61 for its 'blinding effect.' It seems that despite having double the lumens, the illuminance (lux, I guess) is about the same. Effectively, it's about the same brightness, but the beam has about a 30% greater diameter. While this is greatly useful for actually lighting things up to view them in the dark, it's no more effective at blinding a person than the standard P60 bulb. I'm not too convinced that this is worth the diminished runtime.
I wonder if a 9V bulb is any brighter, or just the same with a wider beam... I suppose in order to get a better effect, I have to get the rather bulky Turbohead conversion... Or are there any lenses that fit over the head that I could use instead?

By the way, for those wondering about the G2's blinding power, here the results for myself. I went from moderate light (basically suburban nighttime, streetlights and the like) to almost no light (bedroom, streetlights through the half closed blinds) only briefly, so my eyes were only moderately adjusted for the dark. I pulsed the G2 into a mirror a little under 10 feet away from me once (so the light source would be represented at about 20 feet). When the light went on, my peripheral vision was hazed and washed out and my center vision (45 degrees) was pretty well completely whited out. After the light, my peripheral vision returned instantly, but I had a big purple green spot (like when you rub your eyes too hard) covering ALL of my center vision for about one second, which (over that second) reduced to about 10 to 15 degrees. That smaller spot lasted about another 45 seconds before diminishing enough that it wasn't in any way distracting. My night vision was (obviously) completely eliminated, and I couldn't see much beyond what was lit up by the streetlights.
I'm not sure if it's just me that gets the green purple after effect... I normally get blue for camera flashes, yellow purple for most flashlights.

For CQB purposes, if you're limited to semi, this is sufficient. It's very hard to aim with that giant spot in your vision, and that second of impairment can be enough to put in one well placed shot.
