"The Brothers" Twin stylish 2C mag11's

[Eddie-M]

Hey CPF. Just wanted to show off a couple of my newest lights. I made two of these, one for myself as an EDC for work, and one for my brother (will be the first custom flashlight I have gifted him). They are pretty simple, but classics nonetheless.

The host is your standard 2C maglite. I have used FM's stainless steel deep tailcap to facilitate two AW IMR 2000mah 18650's in series. I also used his bifocal reflector. The stainless steel bezel is from Waion in the BST subforum. I am also using his bipin socket kit for a WA1111 bulb, hooked into the stock maglite switch.

Runtime is about 30 minutes (4amp current draw to bulb). Output starts at a bit above 1000 lumens. It's a small portable powerhouse, great for sweeping the backyard for wildlife and what have you at night (Or in my case looking for stuck packages in conveyor drive systems). I also don't have to wory about anything overheating because it's a pretty modest hotwire mod. I had originaly tried the phillips 5761 bulb, but they would poof on fresh batteries.

And of Couse what build isn't complete with some sort of beamshot comparison?

nice setup

just gotta be careful using freshly charged imr cells because according to the graph, it'll instaflash at 8.4v

another alternative is the rop-hi bulb (pelican 3854 bulb) .... 6.0v bulb that can handle up to 8.5v (~1600 lumens) before flashing and doesnt require bi-pin socket (although a little more expensive)

 

[Eddie-M]

Thanks

No problems on fresh IMR's, the system resistance brings the voltage down to safe levels (haven't tested vbulb yet though to see by how much). I didn't have enough resistance to not poof a philips 5761 on fresh IMR's though, but I will be using that bulb in a regulated build in the future anyway.

Never messed with the ROP mods, didn't know they could handle that much voltage.

I meant 3854 bulb instead of 3853, handle up to 8.5v (~1600 lumens)

 

[Eddie-M]

Wow, thanks. I never even considered that bulb for some reason. That would be the brightest bulb and poof-proofest to use then since I can't use the phillips. Do they offer it in a bipin mode or is it only potted?

*The phillips bulb that I love but have poofed in this light for reference*

This is not true.
Lux used very slow ramp up voltage on his test which you will never get in a flashlight even with soft start regulated system.
Keep in mind that testing a bulb in open air will definetly give you different result than inside head with no air circulation.
There are not enough information for 3854 H bulb but even if you drive a 5761 bulb with soft start and regulated at 7.8 volt (at bulb pins), fillament of the bulb will easily break with small movement and physical shock regardless of 4.3 hours predicted life.
By my experience, you can practically overdrive a bulb when predicted life is about 10 hours or more.
However, all three bulbs (WA1111, ROP HO and 5761) are excellent choice for superbright 2C M*g.
I am glad to see some folks still love colortemperature of incandescent. :thumbsup:

Performance aside, those are beautiful lights. Thanks for sharing.

Great information FM, I never knew the filament was more susceptible to shock when overdriven, and I had not considered that lux's testing in open air would also aid in keeping the bulb a bit cooler.

I love my Incan mods. Wait until you see what I am going to do with your original elephant host (and ma-sha1's extra elephant pieces) that I bought.

Thanks a bunch. I agree, this is instantly my new favorite go-to light; sexy, small, powerful and high CRI.

Gorgeous duo you've got there! Fm's bifocals really bring out the best from your bulb!

 

[Eddie-M]

Thanks! Indeed they do, they really do smooth out the edge of the hotspot into a nice circle and remove beam artifacts 🙂

Nice lights, good to see hi powered incans still being modded. I know there are brighter LED's but these will throw better and set stuff on fire!
