firefly setup options..

[cy]

firefly is one of those ground-breaking lights that when properly setup is one of the best and most reliable lights around.

firefly when not setup properly has one of the worst beams around with unreliable switch function.

further due to the number of choices available to building up firefly. it's possible to custom match up your preference for your firefly build.

it's always compromises... what's more important to you?

1. longer runtime or max brightness.
2. is weight an issue?
4 what about size?
3. are you going to be using li-ion? or std lithium
4. aluminum or copper head
5. 123 or CR2 body
6. how bright do you want you low beam?

was doing a few custom firefly builds for $15-20 over cost of parts at shoppe. had to stop because it taking to much time.

how to's on tuning your optic and tuning your FF two stage switch is posted on dspeck's forum. these two fixes takes care of 99% of complaints directed twards firefly.

note: when using aluminum head, MM lite with Hbin vf is the prefered combo.

hopefully others will jump on and offer their solutions for their custom firefly build..

Hi cy, I am also a Fire~fly supporter, and I totally agree with what you have mentioned.
I have a lot of favourite combinations, Nextgen 500mA, 2-stage swich resistance lowered to 8~9 ohms, J bin Lux III and aluminum head is one of my favourites.
More aluminum heads comming from DSpeck soon.
Some pictures of my Fire~Flys in my web site (Sigline).

I agree, it's an awesome light. A lot of light out of a light, tiny package, and the perfect compromise between size, weight, light and runtime, and very modular too.

I have found that the stock versions (BB650 and MM+) work superbly for me, with the following additions:
-2 stage switch, 16 ohm for a brighter low setting
-SO17XA reflector, a must for high-dome emitters, in my opinion
-Small Dr. Scholl's pad to reduce battery rattle

I have not seen a need to reduce weight/size any further, so I haven't gone to the aluminum head or CR2 body... yet. I prefer the better heatsinking of the copper head and runtime of the CR123. All my other lights use CR123s so I prefer to stock that battery.... for now.

The best part... I can't wait to get my hands on those new emitters. It will be an easy upgrade and will yield an even more incredible light.

I love the FF2. I have a NextGen 750 with a TW0J in mine and I can really tell the difference (especially in runtime) from the stock BB 650. I have tuned the NX05 optic and have a nice beam. I plan on modding a reflector and trying that out, too.

I have Dr. Scholl's pads and they help the switch. I am using a 32 ohm switch, but would like to change to a 16 ohm. It's a little too dim on low for me.
