I would imagine so, seeing as 70% of them still use LED Lenser P7s (gah)!Good choice on the PD35. I'm sure you will love it, and the other officers will be blown away by how bright it is.
Now you just need some good 18650s and a charger to go with it. If you haven't already bought some, I would recommend AW brand 3400mAh 18650 cells, and perhaps a Nitecore i4 charger. I believe Fenix also have their own brand of cells which are no doubt good quality, and you may have already bought some charger with batteries combo pack from the same place you bought your light.
If you are still looking for a light for your bag with lots of throw I would suggest maybe looking at a TK35. It retails for around $99 (£64), although the price from UK dealers may be higher. Alternatively, you could just have a look around this forum and get some ideas for what to do with the 2D Mag that you already own; there are lots of crazy bright mods that you could do.
i have a box of ultra fire branded 18650 batteries that I've used with my other torches in the past, but I picked up a fenix branded 18650 3400mAh to go with this new torch. I imagine it'll be just as good as the AW one, or at least I hope it will be. (It is the same price after all, perhaps it's just a rebranded AW or other decent brand).
i think I'll still pick up the ML300L for my bag, as although there are lights out there like the Thrunite throwers, I just want something simple that I don't want to worry about handing out for other people to use. If I get the 3D variant, that's 650 lumen with a decent focus able reflecter that'll give a good enough throw, and that's good enough for me. Question is, do I run it on alkalines, or buy some more NiMh rechargeables
