just get a Fenix L1P which is the best value and most practical/cost efficient light on the market and forget what your friend thinks. This light will fit on your key chain and put out as much light as a mag 3d. If you decide to go with the mag85 mod let me warn you. It may be incredibly bright but the bulb life is rated at 20 hours and you wont want to leave this thing on for too long because it will heat up the entire light to the point where it's too hot to hold. While the mag85 may be INCREDIBLY bright it is not a verry practical light. also the light beam coming off the mag85 will be bright enough to melt plastic at short range.
I disagree.
According to flashlightreviews.com the 3d mag puts out about
6200 lux, vs approximately 600 for the fenix l1p v2.5. Nowhere near as bright. Sure you can make arguments for the maglite's hotspot being more focussed and so on but there's no question in my mind that the 3d is putting out way more light both in total and in the hotspot than the fenix.
Regarding the heat output of the mag85 - I have run the mag85 for long periods of time and I can definitively say that it is NOT as hot as you think it is. It will melt plastic - but only if the plastic is INSIDE the light assembly AND you run the it much longer than a normal person would usually run it for. The usual problem with that is the switch assembly melting with unpotted bulbs. If you use kiu's high temp bi-pin setup the problem is eliminated. The mag85 certainly does not get too hot to hold. It is NOT an impractical light at all. The infrared (heat) output of the beam will not burn or melt plastic - it doesnt even burn paper. If you're very very very patient and you put bread at close enough range you can toast bread. But burning or melting plastic is definately out of the question.
At 10.8 volts Welch Allyn rate
the bulb for about 12 hours life, I would expect closer to 10, perhaps even less under normal conditions.
Samorlando, definately take up argetni's offer of the mag85s - you can always sell one of the two off and and also sell off your 4d mag. That will put you back into the price range you were talking about.
