ENEDED

are you still testing the xp-l led?

Well, bigger the reflector, tighter the beam, longer the throw. I kind of like it with the XP-L dedomed, should be same beam width as dedomed XM-L2, but I smoked the dedomed XM-L2 U4 1A. Apparently the XP-L's can take more amps, or maybe just lucky with the XP-L?

Yes - still XP-L dedomed.

Guess this puts the pressure on BangGood. I can get the BOSS1 for $47.89 w/347 points deduction with free shipping via America Direct Express. I rarely order anything from GearBest without a discount code, so I've accumulated a bunch of points.

The GearBest code of MAXY works but raises the price. the regular price for the BOSS1 will be $61.55, dunno how long it will be available for $55

Smart move . I will ask for ask their price too.

That beamshot brings hope to achieve near-DEFT level performance under 100 bucks, and getting higher OTF output at the same time. With a taskled H6Flex driver I smoked a domed U4 1A at just 5A, but the XP-L HI V2 1A managed to survive up to 6.5A (with performance loss after).

Looking to see your results Tom

seeing such results with xm-l2 and xp-l emitters makes me wonder what could be achieved with a properly focused xp-g2…

Not just focusing, but power. If I could come close to what Mitko gets from FT XP-G2 S2 2B's (5.5A, even higher he mentioned), I'd be happy. But at 4.0A or 4.2A, the XP-L would probably still beat it.

The UCLp did just come, along with parts desperately needed from Richard Smile.

I dont give up on xp-g2s yet, these leds have outperformed both xml and xpl emitters in terms of throw in virtually all other flashlights, it is very unlikely they do not work in this particular case.

696 kcd max, maybe a steady 685 kcd with the UCLp lens, measured at 10m. 685 kcd is 1655 meters, 5430 feet, 1.03 miles.

One sort of problem - I measured the stock lens at 89.6mm x 2.04 mm and it's a tight fit. the UCLp I requested was 90.0 mm, and measured precisely with my digital caliper at 90.0. All UCLp's are shipped with this blue plastic protective stick-on coating, so with the coating on, I used my rotary tool and brought it down to about 89.80 mm, then it fit fine.

I was hoping the 2.25 mm thickness of the UCLp would tighten things up (0.21 mm thicker than stock), maybe get a better focus, but it had the opposite effect - initially with it all tight, I could not break 600 kcd. Loosening up the bezel bumped it up big time, so it seems like the best focus point is a little further out of the reflector, not further in, if I understand the dynamics. I may need to bump up the height a little now - could use a stick-on type of ring - the 3M type, that the centering piece can sit on.

Hoping I got time for this but my plans would be:

  • put copper extensions on the MCPCB pads to clear the reflector base
  • add in a driver and use 18 AWG LED wires
  • I got 2 brass screws holding the shelf down now - add 2 more, total of 4

It's not an ideal heat sink setup, but it seems to be working pretty well. There isn't much output droppage in short runs.

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.
