Skyray XML-T6 light - upgrade

LED Flashlights – General Info 18650 Flashlights

Hi flash-aholics ;)

I'm new on this forum but was reading on it for some time.

Because my PrincetonTec tec40, (a flashlight with regular bulb and 4xAA that i've been using for years) stopped working, I was looking for something else.

So than I bought this light because i wanted to try a led flaslight and it didn't seem expansive at all:

http://www.ebay.com/itm/CREE-XM-L-T6-LED-1000Lum-Flashlight-Torch-3-7v-Charger-/330566331641

I'm surprised in a positive way by it's manufacturing quality and size, downside for me are the flash modes I don't like.

Now this light is much, much better than my old one. But interested in the led technology I went to do some research and came upon this site.

Reading some threads here I think this light puts out maybe 300-400 lumens, with a tailcap reading of 0.7a max. Does anyone has any experience with this particular light?

I've read about upgrading the XML with a driver drop-in that can output to 800-900 lumens. Is this possible for this light also, or are the batteries not up to that task? Can I get rid of the flash modes by upgrading it at the same time?

BTW; I would prefer buying from ebay, as I'm located in Europe.

I believe this will fit in that host - but I'm sure someone with sky-ray experience will confirm.

This would give you more lumens and change you to a 3-mode (High, Medium, Low).

Your batteries will work, but they're pretty crappy - to be honest.. That charger is pretty much crap as well...

You can get that drop-in a little cheaper at manafont, but if you prefer ebay, that's the one to get..

I think they may have changed the description in the one linked above to one with a strobe.

At a glance, I didn't see many drop-ins on ebay. If you don't mind waiting a while for shipping, you could get something like this from China:

Your batteries & charger indeed aren't any good.. Get a Xtar WP2 II ($18, dual-bay) or Xtar MP1S ($10, single-bay) and pair of good batteries - e.g. Hi-Max 2600mAh ($19 for pair), Solarforce 2400mAh ($14 for pair). Bad charger + bad battery eventually can result in either fire or explosion.. so be aware of that.

And what about the Xtar 3100mah battery? Looks like a nice set.

3100mAh one has less useable capacity in single-cell light, because it drops voltage way quicker than 2600mAh cell.

As you can see, at 2A and 3A (range in which your flashlight most likely works) 2600mAh cell has more useable capacity.

This is probably the one i'm going to order, only not sure about what battery to order from that site. I'm thinking about this one:

SANYO UR18650FM

http://www.intl-outdoor.com/sanyo-18650-2600mah-liion-battery-p-135.html


Sanyo 18650 Unprotected

Capacity: 2600mAh

Full charge: 4.2V

Nominal voltage: 3.7V

Cut off: 2.75V



with this charger:


ML-102


http://www.intl-outdoor.com/ml102-usb-charger-for-18650-26650-battery-p-243.html


Is that a good combo?

Those batteries are unprotected, are you sure you want to deal with unprotected batteries? I've heard that people like that charger, but I would choose a more "standard" type charger myself like the Xtar WP2 II mentioned above. I don't really see a good choice for a "protected" battery from Int'l Outdoor.

That charger from ML-102 charger is good. Make sure the power supply is good, the one from the Ipad for example (not the fakes).

For what Shadowww says, yes true but the Redislast and IOS have the same capacity at 3A down to 3.4V as the Xtar 2600.

I would choose this graph as a reference down to 3.2V due to intense heat the Vf of the LED will drop from 3.35V anyway. And lower draws than 3Amps, 3.2V is ok.

Anyway, XTAR 2600 are a good option.
