Default Maglite 3 AA led flashlight

Recently Maglight has taken it upon themselves to move over to the world of Luxeons and have made a production flashlight I'm sure we've all seen that includes a 3 watt Luxeon running off 2 or 3 AA batteries. *Most of the light modifications I'm doing are converting flashlights into lasers. *So I picked up one of these maglites with the intent of checking it's usability as a laser mod. *The journey there is interesting and I'd like to share with you all over here on the light side the modification I've done. (I did not use this as a laser and don't think it's going to be an easy mod but it can be done.) *



Obviously, in order to utilize a luxeon led, you need to have some kind of current regulation. *To keep the led at a consistent output current wise regardless of battery condition. *So, I figured the regulator in there may be putting out right around where I need it to use for a laser. *Well, it doesn't! *Oh it's regulated alright. *But the regulator is running 650ma at exactly 3v. *In regards to current regulation for a Luxeon 3 watt, it's a bit weak. *If I remember correctly the 3 watt could handle 750ma Nicely. *Now there isn't much heatsink under the LED so I'm sure Maglight figured that into the equation. (thankfully it's not a K2! and it's heat generating horridness) *I've recently been shown the cree Q5 and would like to see if this is going to be a reasonable swap for the 3 watt led in it. *







1. the reflector. * Nice long reflector for those nice tight beams.







2. the driver and light.















The beam (first as powered on spot)





Middle of the road (flood/spot)





Head almost off (flood)





I'm pretty impressed with this light. *It's more powerfull brightness wise than any of the dorcy's I've got (not that they are all that bright) but they are sure bright for me. *Having 3 batteries means longer run time and I like the feel of the mini mag that is a big longer like the larger D sized maglights. *I'm no flashaholic but the beam looks good tight and starts to turn to crap after the thing goes to flood.



I've no doubt I could put a cree p4 in this and not have too many issues. *The hardest would be trying to come up with some means of heatsinking it so that I don't cook the light while trying to make it brighter.



So, there is my ramblings. *Hope it benefits someone. *I know it was fun to open it up and figure it's inner workings.

Default Re: Maglite 3 AAA led flashlight

You weren't wrong when you said it didn't have much in the way of heatsinking !! Jayrob has already put a Q5 emitter in a different torch. http://www.laserpointerforums.com/fo...num=1194770080

Should be awesome in a minimag though
