Re: Mag 3300L

I'm in for a dropin, 3spd. I assume I can purchase battery sleeves from you as well? I'll put Run4JC in for one as well...:nana: :devil: :thumbsup:

Thanks, Scout24 - yup, I'm in, although I think I'd like a full light with tail switch, $375.....

Re: Mag 3300L

I'm interested in the full light. So that would be $375? Does that include batteries?

And what best to charge it with? I don't think those bad boys are going to fit in the same charger I use for my 18650s. Maybe they do, I dunno.
 
Re: Mag 3300L

Any chance you will offer a copper heatsink to keep the lumens up for longer than 10 second runs?
 
Re: Mag 3300L

I'm definitely in for a full light with 4500K! I can't wait!!!!!! lovecpf

How do you figure? 10 second runs?

First off sorry for the cavalier initial post. I should have been more specific since my goal is not to aggravate.

All the high lumen lights that undergo sphere testing show dramatic lumen drops within seconds due to the substantial heat dump due to the amount of wattage within a relatively small area. I am presuming at least 3.33 watts per emitter on high so 9x3.33=30 watts.

Without a nice chunk of copper copper to wick that heat away after 10 seconds on high I believe there will be about a 10+% lumen drop from what I have personally seen during light sphere testing.

I believe this is an issue for anybody designing a light that uses that much power.

Take a look at this post. Both lights are essentially identical except for the copper vs aluminum heatsink & are using 30+ watts on high.

If you look at the percentage & ignore the likely Vf differences of the luminus led there is a hard to ignore difference between the two heatsink materials.

p.s. I bring this forward because I recently received your EDC(in Al for better thermal perf.) & love your craftsmanship. But since I own a Vara 2K light I know how important in my opinion copper is to these "light howitzers".
 
Re: Mag 3300L

I have no plans to offer this in copper as at $275 now it is very expensive. 2" x 2" of copper would be 10x the cost of the aluminum and I think in "Real Word" use the difference of a couple hundred lumen's when where talking 3000 LED lumen's does not warrant the cost or more so the weight increase.

Those tests are great but are really not accurate in my opinion. You need to do the same test with 2 identical heatsinks in each material, to make the test accurate you need to use the same LED and regulated power source.

Mac-

I think I'm going to need to order one of these when you make them available. Please add me to any list you may have.

Thanks.
