Just ordered a pd35 and some boys at work says that 185m range is crap and I should have stayed with led lenser, they've just ordered the p7.2 with twice the range of mine for less money. Please tell me there wrong
All you need to do is look at the cd of the lights....and that tells you how much light they will have on a target at what range.
The cd will NOT tell you how wide an area will be lit up at that level of illumination, only the lux at any given range.
Lumens tell you how much total light there is, and cd tells you how far that light is thrown.
If you WANTED a light just to say it throws farther than their light, simply find the cd of their light, and get one with say double the cd...and you win...if its ONLY about maximum range, and not about the size of the spot when it gets there.
BTW - YOUR light is regulated, so the brightness, once stabilized, stays at a constant rate.
The P7 is not regulated, and IIRC is only ~ 175 lumens max......meaning that as the cells drain, it gets progressively dimmer, and, therefore, loses range as the cells drain.
Its max is 210 meters, which calculates to ~ 11k cd.
So it STARTS at ~ 11k cd, and drops from there. (Fresh cells will refresh that)
The pd35 starts at ~ 8.6k cd, but has a thermal step down to about half that.
That means your buddies are correct, you have more lumens, and can light up more at a time, but, they can hit things further away, but with a smaller dot of light.
