Wow, I thought they were regulated. That sucks.We did a review of the P5R a couple months back, here's the link: http://www.led-resource.com/2011/09/led-lenser-p5r-review/
Hope this helps!
Me too, i prefer real flashlights. Olight, Fenix, 4Sevens, Eagtac, all good stuff and less costly than German lensersthey are mostly disapointed *** soon as they have seen Surefire or similar "real" flaslights.

If it maintains regulation that well, it would not be able to reach 3 hours runtime. Since that review was from a while ago, it's possible that there are multiple versions of the light because LED Lenser was purchased by Leatherman, and the output rating was reduced to 200 lumens. They also didn't state a runtime on high in the review...Hmmm. I've been enjoying my new P5R for about 2 weeks. My light's output seems better regulated. Indeed, this German review (Google's English translation here) found the P5R's regulation impressive:
Praxistest Laufzeitmessung:
beim Einschalten: 11.400 Lux
nach 5 Minuten: 11.300 Lux
nach 10 Minuten: 11.100 Lux
nach 15 Minuten: 10.400 Lux
nach 20 Minuten: 10.000 Lux
nach 25 Minuten: 9.600 Lux
nach 30 Minuten: 9.000 Lux
nach 35 Minuten: 8.300 Lux
nach 40 Minuten: 5.400 Lux
What's the serial number of your light? Is is closer to mine, or the one in that review?
I've seen three claims:Since that review was from a while ago, it's possible that there are multiple versions of the light because LED Lenser was purchased by Leatherman, and the output rating was reduced to 200 lumens.
