Re: Led Lenser p7
Gidday and welcome to CPF.
Is it possible you're referring to regulation/modes of the light as opposed to problems? LL i think, are trying to address this with some of their newer models. I own a few LL's, among them P7, P14 which have virtually no regulation, and start to dim after just a few minutes on high. Not to say they're not a good torch, but as davyro says, there are heaps of great value, well regulated lights available to choose from now. If you like the looks, size of the P7, you might find the single 18650 cell format a good place to start looking. There's an absolute plethora of styles/ manafacturers to choose from.
Have fun!!
