Ota's Beamshot Thread... [Very Picture Heavy ✰ Updated 2016/02/09]

Well done .

Thanks for sharing .

Added a tailcap amp spreadsheet in the OP.

Right now I only have the ZeusRay and the OEM SK98 from FT. In the ideal situation (factory problems set aside), I'd have to pick the ZeusRay.

The UR18650s, the FM in this case do very well for daily driver use. All of my other cells are LCO and report around the same internal resistance from my Lii-260 (50-60mR), so I suspect the amps I recorded are at peak performance without having to move to LMN cells or doing more driver mods.

Thanks for the reply! I have a bunch of those, and I was wondering what the deal was. Some people seem to think they aren't very good, but that link and a couple other reviews I've seen pretty much say they are just as good as any. was contemplating buying efests but I don't think it's really necessary.

Added some more sets starting with 'Tangspower AK-96 LG H35C1 LEMWA-FX w/ Stock Driver Bypassed @ ~2.00A'

Added some more slight mods and links that I overlooked (might not even consider them mods ;) )
and a tailcap amp spreadsheet at the top of the OP.

More beamshots up starting with "Convoy S6 XM-L2 U3-1A Dedomed w/ 10*7135 (8*380mA+2*350mA) Qlite guppydrv"

More beamshots starting from "Ultrafire HD2011 XM-L U3-1A w/ 8*7135 (8*350mA) 105c"!

My latest Convoy C8 rebuild is my new favorite C8 :party:

Beamshots are always nice. Thank you for the effort! :beer:

Thanks Ota. I have the SF 348 in front of me now. I quite like it.

Added more beamshots starting with "Roche F12 XM-L T6-1A w/ 8*7135 (8*350mA) 105c"

I also got to play with my Eagle Eye X2 (practically an S2+ or other way around) sporting a Carclo 10197, and I freaking love it!

Noob question.

I currently have a Convoy C8 OP XM-L2 8*7135.

What is the easiest way to get the XP-G2 in there?

How would my OP reflector affect your Convoy C8 SMO XP-G2 beamshot?

I would like a larger, smoother hot spot like your C8 SMO XM-L2 but still keep the spill down like your Convoy C8 SMO XP-G2 (don’t want to light up the pavement).

My setup was a little botched, but I rotated my XM-L butterfly spacer 45deg and had it rest under the tap screws so they don't move once I started to screw in the bezel. I'm not sure if there is an XP -> XM reflector converter, but there is one for vice versa.

As for a smaller spill, I'm not too sure how to alleviate that one. Maybe someone else can chime in?

When I took the C8 SMO XP-G2 beamshots the light was positioned behind the camera, so it didn't get the immediate spill. The XM-L2 beamshots had the light side by side to the camera, so I believe the spill in the SMO between the two would be roughly the same maybe a little less with the XP-G2.

An OP reflector would probably do the opposite of what you want, making the spill brighter, but with a smoother hotspot.

Here's a ceiling shot (~2m) with the XP-G2 with the OP reflector. Not sure if it's useful.

So the apparent difference in spill is mostly due to the camera angle and not the emitters? I was hoping to reduce the spill from my C8.

Jorg

In this case yeah :( Don't get me wrong though, I'm sure it's possible.

Wow great work so far! Love the family picture, awesome presentation!

Added a couple more beam shots, especially "Stock Convoy S2 OP XM-L2 U2-1B w/ 8*7135 (8*350mA) 105d " since I didn't have any. I have a lot lights coming in soon and will have beam shots for those too.

More beamshots added at the end of the OP: SupFire F3-L2, (de)domed, and a Convoy S2 XHP50, and a possibly useful picture, mouse over.

Finally got to adding more pictures, esp beamshots of the NW and CW BLF A6.

  • Courui D01 CW XM-L2 w/ Stock Driver
  • Ultrafire F13 CW XM-L2 w/ Stock Driver
  • GearBest Fake Convoy S2+ CW XM-L2 w/ 105d(?)
  • BLF Manker A6 XP-L ??-1A w/ A17DD + 1*7135
  • BLF Manker A6 XP-L ??-3D w/ A17DD +1 7135
  • Convoy S2 XHP50 J2-1A w/ Cell DD & 22AWG Jumper @ ~7A
I think my white balance is all messed up even though I've been using the Daylight setting in all of my beamshots :|

Lots of work to make this thread. Very good reference info for beam pattern and brightness. Thank you

Great work, Ota! Your hard work is much appreciated.

Added a couple of beamshots from a new spot since my old spot is being affected by a really really nice form of light pollution. Even then there's slight light pollution hence why the camera is pointed upward :evil:

distance to garage is 23m
