Building a 500+ lumen light

[scubasteve1942]

I want to put together a 500+ lumen light. Right now im thinking about getting a KT2 head, a MN21 LA, this body http://www.lighthound.com/index.asp?PageAction=VIEWPROD&ProdID=2618 and 2 18650 batteries. Does this sound like a good setup? Any other ideas?

Looks like a good set-up, just don't forget your tailcap That set-up should yield you 600+ lumens out the front on freshly charged cells. I suggest that you get at least 2400mah capacity cells for the MN21 LA...as the MN21 draws a lot of current and the more capacity the better

Wow.. cool!!! 600+ lumens upfront for how long??? runtime wise??

I just made one, Leef body 2x18650's, KT1 TH and an MN21. It's bright! I love mine.

I don't have this set-up, but from what I have read you should get about 20-30min of runtime. Although you will see 600+ lumens out the front at the start, output will gradually drop throughout the burn cycle...although I am willing to bet you would see 500+ for the first 10min or so :naughty:

.....couldn't he do it a hell of a lot cheaper than that?

just trying to help.

he could build a 2C ROP(with AW C cells) with longer runtime, similar output, slightly bulkier size, and be up and running for under $150. which is less than the cost of the leaf body+turbo head alone. but there are bonuses to the expensive SF lego option also.

Actually what bonuses would there be to a SF lego option versus a 2C ROP?? Just curious

wondering.
All my SFs have slightly (or considerably) melted glasses, even the 6P in original state!

As this might use the same head, how can it survive?
Heat much be much higher.

Size and quality are the biggest ones, just comparing the individual lights. I've built a couple of ROPs, plus used the Leef C-C 2x18650/KT2/MN21 combo(matter of fact I'm going back to it after killing my MN16s, just waiting on unprotected batteries to get here).
The ROP with MOP reflector put out more light than the MN21, and I was very pleased with it. Throw was good in spite of a huge hotspot, and the spill was incredible. But...it was too big and bulky. I rarely carried or used it after the first few days. The Leef body with KT2 goes between the seats of my truck, and in my bag when I go in to work. I use it every day.

What bonus to a SF Lego?
Assuming the same setup I have, with the C-C body as a base...
You can use all of the 9 and 12V turbohead lamp assemblies depending on your battery choices.
Also, a Z41-HA or M2 bezel that takes all of the 9V SF, Wolf-Eyes, Lumens Factory and other "D26" lamp assemblies, inlcuding some 12V ones from G&P, etc.
I've run a KL5 on it. A KL3 would work, too.
With the C-M adapter, I can use the Z46 M3 bezel and KT4 turbohead on the same body. If I had a KL2 or KL6, I could use those, too.

I don't actually do any of that, since I use it as a dedicated light, and really don't find the "Lego" options useful at all, but maybe some people do. It does give you a lot of options.
