Well, a regular well focused FT S2 1A( the cheaper one , they have too s2 1a in their store, the cheaper is the better) driven at 4.4 amps gives like 10% more cds of the XMP/XPL champion at 6 amps - V6 1D( still havent tested V6 1A/V6 2D) a hard driven s2 2b is maybe >25% better, you can see the difference even with a naked eye and its an observation of literaly dozents builded C8s

That “thing” has been ordered ofc :slight_smile: Cant miss it, it could be made a great search light, great indeed…too bad onone of the GB codes that i have worked :confused:

Yea, I'm taking a big chance with the FT XP-L V6 0D, but seems to be performing well.

Measured amps again and I'm getting 6.08A - this is after I cleaned up contacts of the DMM wires and banana plug connectors though (before I got 5.95A), but cells are as-is, not freshened, when I did my throw measurements this evening.

Mitko - cool you ordered one! Love to see your thoughts and results. Certainly should hit over 700 kcd, and running a dedomed XP-G2 at over 5A I would think could hit over 800 kcd.

Looked at it - interesting, more like a classic SRK setup. Hope those are screws holding down the driver contact board, and hope it's not glued - I don't see a driver retaining ring. Kind of pricey, but of course it's a SolarStorm so maybe decent quality, plus all those emitters, side switch is great of course. Head diameter is slightly smaller, maybe about a Shocker size. Should be throwy, because with 6 LED's, the reflectors have a decent size. The Shocker is bout equal to 3 C8 reflectors, and I measured close to 600 kcd on one of them, in 500's on most, all with dedomed XM-L2 U2 1A's getting over 5A to each LED.

The 6-9 days for shipping usually means they don't have them. With BG, that time scares me because it can slip way longer.

I imagine the driver is press-fit/glued like the Solarstorm SP03. The R60T looks like the perfect companion for the SP03. If I win the powerball, that’s the first light I’ll get

I got it, Thanks :wink:

If you are getting close to 700Kcd with an XP-L, I'm betting an XP-G2 will be pushing 900Kcd.

Well, you wont get any bonus using XPG2 in that case even using a nice scope , just less lumens, its like TK61 - when modded with V6 1D it gave arround 600k mcds, using XPG2 it gave 820 but it was a downgrade from my point of veiw:i could see jackal eyes at 2.5 kilometers with both setups yet the XPL hotspot covered a larger area

Mitko - I tried two more XP-G2 S2 2B's from FastTech on copper MCPCB's last night, and again, can only get about 4.2A max on a direct wired, no driver, soldered up bench setup using a LG HE2 @4.22v. Did not even dedome them yet. Now I looked up when I ordered these, and it was back in Aug and Sep 2014 - 1 1/2 years ago. Wonder if the newer batch's performed better? I got slightly lower amps on a Samsung 30Q @4.22v, so figure the HE2 cells do good. My old SONY VTC5's always do worse than the HE2's and 30Q's, think I spot checked one and performed lower.

I ordered qty 3 more of the FT XP-G2 S2 2B's over the weekend, just to see if latest batch FT has is any better. How are you reflowing yours? I've been using a butane torch as of late - quick method. I used to use a frying pan and bring up the heat slowly, similar to what CREE recommends. No idea if one method is really any better than the other...

I hear you bout the small XP-G2 hot spot. I recall guys complaining about the tight hot spot of the early OSTS version of the TN31 using a XP-G2. I kind of like the results I got with the XP-L, and now that's it's solid over a mile, I'm pretty happy with the results.

could someone post a photo comparing hotspots of both xp-g2 and xm-l2 in the same reflector?

Tom, based on Mitko’s results I went ahead and ordered 8 S2-B2’s from FT. Also ordered 4 from Mtn. After I received them I hot de-domed 1 from each supplier. I, like you, was only able to achieve around 4.2-4.3a. Not sure what to make of all of this, but would like to figure it out.

Oh boy, think you mentioned this before - totally forgot. I trust Mitko but I would certainly like to understand what's goin in.

Fenix TK 61, with XP-G2 de-domed vs. XP-L de-domed

XP-G2

XP-L

I worked hard on this particular light, had issues with current spikes frying emitters, tossed 8 XM-L2’s in the trash. Traded it off to Richard with a 32mm Noctigon sporting the de-domed XP-L emitter doing up close to 600Kcd. Hate plastic reflectors.

Yeah I never had any crazy results from those S2-2B’s either. I’ve never had any XP-G2 go over 5amps. Recently I started ordering their S2-1D’s because I like the tint better.

is there a driver that will drive them ( the xp-g2s) over 5 amps AND is small enough to be used in the boss1?

Well, think I posted earlier - there is some vertical room, so it's not all that bad. Problem is you need a high amp boost, or high amp buck driver and somehow manage cells in series, like a big battery mod done by CWK above, or using 4-5 pair of 18350's (might fit 5 pair, but 4 definite).

I think if we used a zener mod FET driver with a 2S setup, there would be too much voltage to burn off - not sure, others may know better.

Yeah you can’t use a zener FET 2S on a 3v emitter, it would fry instantly. The emitter would get the full 8.4v.

If somehow this driver: https://budgetlightforum.com/t/-/37354 could be cranked up to 5A or so to the LED and output voltage reduced, it would be a great match for this light. You could make the driver diameter much much bigger for the BOSS1 - width is no problem at all .

Dale - that's a great example. I don't have two de-domed matching lights, least I know of off hand. I thought though there would be examples around, maybe going way back: rdrfronty, relic38, ILIKEFLASHLIGHTS, RaceR86 etc., plus a few others that posted some real classic stuff. One guy who did mostly de-domed throwers had some great beamshot posts, think from Eastern Europe -- he was pioneering de-domed LED's at the time I thought, and had some great comparison shots.

Edit: Found it!! It's viffer750, shots here: https://budgetlightforum.com/t/-/12247.

But this is one of rdrfronty's classic, lists a XP-G2 and XM-L2 TM31, both dedomed: https://budgetlightforum.com/t/-/25465 (I did the XM-L2 dedome ).

Yes, XM / XP-L is much more practical, as Dale's photos above illustrate.

The XP-G2 S4's seem to do well. With the testing I've been doing recently on the KD86mm reflector, I have one running at a solid 5.4A (slightly higher on start-up), & that's measured through the DMM, so likely to be higher (roll out the clamp meters...).

I tried a little over 6A, but popped one straight away. I'm betting it's the spike at turn-on which pushes it over the edge.

Got some replacements coming in from IOS :)
