Bought this on ebay, it came with 2 UltraFire 18650 li-ion cells (operates on a single 18650), 12v and 110v charger that plugs directly into the flashlight body. It is a very bright light, comparable in output to my Skilhunt X-1 although not nearly as sexy. The runtime is poor on high, maybe 15 minutes or so on the high setting. I have searched for a model number of this light, or one that looks similar to it, but so far have been unsuccessful. Is the Q5 the model number? I am trying to determine the input voltage limit for operation. My question is this; would this light run longer with 2 - cr123 cells if the operating voltage is acceptable? Would a better quality 18650 be beneficial? I have read several posts regarding lack of quality with UltraFire batteries, and I do have a Lighthound account as I have ordered from them previously. Is this a "budget light"? Would my thread have been better suited for that forum? I apologize if it should have been there.

Here are a few pictures, anyone recognize the model? Is there knock off UltraFire flashlights out there?

The Q5 is probably the led ie cree xr-e q5.

Those red ultrafires are garbage. I would go for a decent battery ie AW or similar.
Dont know the input voltages accepted by this light, if its up to 4.2v then 2x cr123 is a no. If more then they are a possibility. 15 mins for an xr-e on an 18650 is way short, if you get some better batteries then worth testing how charged they are after charging in the light - measure voltage.

Got a link to where you bought it?

you bet, got it here.... http://www.ebay.ca/itm/180728699064?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_4186wt_952





I
have charged the other 18650 that came with it and will give it a go to see if it is the fault of the first 18650 that I put in. Thank you for your response.

As they dont mention input voltages it would be taking a chance with 2x cr123 (6v), up to you but you may fry the driver/led.

Did you charge the second 18650 in the light? Would be handy to see what voltage it was fully charged. I assume you charged the first 18650 before your 15min trial? They dont usually come fully charged. Anyway, as i said, those are garbage. You should get well over 1hr, prob more like 2hrs+.

I plugged it in when I got it home the first time to let it fully charge. The charger has a light on it that is green when not plugged into the flashlight, when charging it turns red and you can see it gradually turning green as it reaches full charge. I think I will just order a few AW 18650's and a proper charger for them from Lighthound, I figured it should last a bit longer than 15 mins. Thanks for your help!

No probs.
Get yourself a cheap multimeter if you dont have one. Can be had for $5, important when checking batteries and would help see what the inbuilt charger is up to.
