KEYGOS M10 26650 FLASHLIGHT-Quick and dirty review

any one know if the c8 reflector fits the m10?

Good news.

Today I received another Keygos M10.

Driver is still 20mm, but these M10 have 17mm ring. No problem for driver swap

Take a pic of driver etc, do solder joints look intact, does emitter look OK? Battery deffo OK, check with meter? Clean all threads, tighten inside of tail cap… um not sure after that but try those and see what happens

This may help, different lights but maybe relevant, as posted by a guy on bikeradar:

My M10 had bad joints...spring in tailcap and front battery spring both broke in first day.

Does any one here have the C8 and the Keygos M10?

I have KD C8 OP and Keygos M10

how would you compare the c8 and m10?....any idea if the c8 reflector fits into the m10?
im quite happy with my m10.

Thanks Jeansy, I am all thumbs. However, true to the character and comradmanship of BLF members, another poster offered to check it out for me. I sent the M10 to them, and they did all what you stated above. It was one of those things you suggested to look for. I think solder points was the culpurt. Anyway, the member fixed it for me, kept it for another couple days to see if it would malfunction. It didn't, and now it is on its way back to me..Wink

Great place and great people we have here!

Thanks for the response and feedback,

Sparky, your avatar has me cracking up laughing everytime I see it. I can't stop!! Laughing

That is so cool!

Ive just done the dry joints in mine...they were very poorly done indeed.

The reflector is 6mm deeper, so it won't fit.

I think m10 is more of a thrower and slightly brighter, since its driver delivers 3.3A to the led.

please could you tell me the size of the glass lens on m10.

i cracked mine and am to scared to open it because the glass fill come out and it will be unusable.

any idea where i could find a replacement?

I think that C8 lens is the same size

Yes, my KD C8 lens fits nicely.

Great, now how does one get a KD C8 lens? Where can they order one? That is what Sparky needs.. Wink

International Outdoor sells AR coated 42mm lenses for C8's at $1.95ea with free shipping if you get three (no brainer to me to get three). Says 98% transmittance. I just received an order from them placed 4/17/12, shipped 4/18/12, arrived 5/5/12.

Ordered a pair of M10s from ebay to mount on my bicycle back in early May. They finally arrived late last week. One was non-functional (LED leads appear to have been pinched-off when the head was assembled) but the fix was simple enough. Paired them with TF 26650s and finally got a chance to do some dusk riding tonight to test them out.

Previously, I'd been using my Fenix TK45 (3x XPG-R5, 760lm) on the bicycle so that's what I'll compare them against. Sorry, no beamshot comparisons.

Here are my observations in no particular order:

1) These guys are being sold on ebay as 1600lm lights. I knew before I ordered that it was inflated so I'm not upset about that. I don't have any measuring equipment but bouncing the light off the ceiling yields roughly the same amount of room illumination as the TK45.

2) The TK45, being basically pure flood, illuminates the whole road/trail ahead and a good amount of stuff off to either side. It also tends to annoy oncoming bikers. In contrast, the M10s project a well-defined hotspot. They do have usable spill but it's not the soft wall of light that the TK45 produces.

3) After ~30 minutes of 12-15mph riding in 77F ambient temperatures with the M10s both on 'high', the heads were warm. I'd guess around 90F. So the heat fins work okay. I wonder, though, if they'd perform better if they ran parallel to the length of the body.

4) I was passed by a number of cars tonight and as they passed me, I compared their headlight beam patterns and brightness to bicycle. My lights were comparable in brightness to a pair of older car headlights. All of the cars with HID headlights were definitely brighter.

Verdict... I don't think I'd be comfortable with just one M10 on the bike. I'm too spoiled by the TK45's spill. A pair of M10s, one aimed 15ft ahead and the other aimed 40ft ahead, works okay. The best solution, though, is probably to pair a single M10 with another XML light with a smaller reflector. (edit: original 15ft & 20ft distances were too close. definitely had a few seconds to react to objects in the combined elongated hotspot so the second light had to be aimed further out...)

sacra, great report!

Like you, I am bicycle and just recently turned into a flashlight person too.. I run a lot of lights on my bikes, all road bikes, and all lights are run in PAIRS.. The M10 is my favorite, and I run it just like you found out. In pairs, one a little further then the other.. Also, to assist the pair of M10s, I run a 26650 helmet light too..

Just checked on the TK45, wow, the M10 should just take a bow for even being mentioned in the same sentence with a TK45!!! Laughing I can get 5, 6 or maybe SEVEN M10s for the price of one TK45!! :) Also, for my bikes, I like the short form factor lights. The M10 fits right in.. Also, if you haven't checked it out, here is a another winner in cheap, powerful light with short form factor, and cheap price.. Got a pair of these too..

Again, nice report and safe riding to you,

for $18.89? :wink:
