Ill get in touch soon. Been workin a lot and have not had much time.
Would you still be interested in one of the heatsinks? I will have some time in the next couple of weeks and could do one up for you out of either copper or aluminum. If you are using the same stars and optics, I can make it the same thickness as the one I used so it should fit. Lemme if you are still interested.
I'm new here but I've had a flashlight fetish for years. I am an anodizer in my other life and I am familiar with the anodize film on Maglites. The thickness of the anodize will typically be nearly a mil and will have to be more than half a mil to accept enough dye. Black will require at least 0.7-0.8 mil and other factors will limit the film to about a mil. But be aware that anodize is aluminum oxide and so it consumes some aluminum to make the anodize. The rule of thumb is that a mil of anodize will grow the dimension by 0.5 mil.
I am also familiar enough with Maglite (how do you like the %$#&*! snap rings?) to know that they make minor variations all the time.
And having cut many heads in half I know there is a lot of meat at the base of the head where you could machine groves to dissipate the heat. Also heat sink compound will help a great deal if you apply it to all metal to metal junctions including the threads.
Also, my I ask what you are doing to improve contact resistance?
So is it just my old eyes, or does the Maglite now have no reflector?
Welcome , beaker
This mod does not. It has individual optics on the emitters.
Yeah I have modded a ton of mags, and they all seem to be a little different in one way or another. There is a ton of meat to machine grooves if you wanted-it would help dissipate heat. As for improving resistance, I have ran a copper wire through the tailcap spring so the wire is the path to ground, cleaned everything with deoxit, and everything I could to the switch. All added up it made a pretty big difference, prob because it was n old well used mag with a dirty switch to begin with.
Wow, very cool U, thanks for the nice writeup! Impressive, tidy piece of work here. And 4000 lumens!!! I would also love to see a comparison with one of the 3 * XM-L beasts. Do you own one to compare it with?
Frontpage'd and Sticky'd.
I have a derwichtel triple XML that is driven at 2.8 amps per emitter to compare it with. I wanted to do a bunch of beamshots of lights thatI have, both modded and stock, but between work, all the rain we have had, and trying to prepare for the hurricane coming, I have not had time. I will be building a triple XML for a friend, and will take shots of that also. If all goes well I will be able to take at least some shots the end of next week and will post them asap. I can tell you that it looks much brighter than my triple xml, much more of a difference than I thought it would be.
I will be posting beamshots tonight after I take them. Will shoot my Derwichtel triple, and a P60 XML drop in for reference.
that is one wicked light! can't wait for some beamshots!
Beam shots posted in general led lights.
Waiting to hear from you on a price for the heatsink... now your beamshot thread got me all inspired!

I will price the metal and let you know. If I make it out of aluminum prob be about 8 to 10 bucks plus shipping.
Cool! Doesn't have to be copper. My monthly gets deposited on the 2nd Wed. of each month so that's when to hit me up. I definitely want one. I'm gonna power it with 4 Shiningbeam drivers and use neutral stars.

When I get time ill make one up out of aluminum. I need to repost the beamshots of this light, as I fully charged the batteries and was surprised how much brighter it is with them topped off. You really have to see this light in person, as the beamshots just do not do it justice.
OK... I'm getting anxious now... wanna go ahead on it.
Rich
Very nice mod, BTW, is the batteryspace or batterystation?
The batteries are from batteryspace. Here is a link to the ones I am using http://www.batteryspace.com/lifepo426650cell32v3300mah16.5arate10whunapproved.aspx Tried the light with one IMR 26650 and 2 of the lifepo4 batts. Pulls 5.4 amps at the tail or 1.35 amps per emitter. This should be over 5000 lumens.
The link dosent show a item...
