plus -10% to all item

But only from 26.11- 30.11 with code: 10blackfriday

That's not a Q3

They seemed to have used a flash in their photos, which may have oscured the emitter. But you're right, the emitter looks odd.

what about this one http://www.lightake.com/detail.do/sku.ZY_C61_Cree_Q3_Power_Flashlight_Torch_Black-27021

That's a cree Q3 but the build quality will be poor compared to the other light.

Dam I ordered 2 light for $19.98 and both have generic Leds in them.

Just ran the light against the Trustfire R5-A3.

The Trustfire is slightly brighter on NiMH than this light running on 16340.

This light has a pure white beam, the spread reminds me of a XPG led.



I put these unprotected batteries 1000 mAh 16340 in my ultrafire wf139 and my 7dayshop charger. They charged the batteries to 4.40v and 4.42v Is this safe.

What is the correct voltage for a unprotected battery of the charger?

They should cut out at 4.20V! Those voltages are way too high.

I have 2 16340 and 2 18650, all 4 are unprotected, I have 3 chargers all the chargers charge unprotected batteries to 4.40v and protected batteries 4.2v, are you saying all my unprotected batteries are dud?

No it either means your chargers suck or your method of measuring voltage is faulty.

All of my protected/unprotected cut off at exactly 4.19V. I use the Trustfire TR001 http://www.dealextreme.com/details.dx/sku.4151

The maximun limit is 4,25volt. Above that voltage reduce battery life and increase risk of explosion

The first time I charged the batteries they all charged to 4.6V now they charge to 4.24(max)v on all the chargers.

At those voltages you are lucky not to have had a fire. I'm actually inclined to suspect the voltmeter as I would have expected flames by 4.5V

Probably those batts are bad built or has "impurezas" inside the chemistry.


Bad, bad, very bad. Check voltages again with another multimeter, if they continues being >4,3 volt recycle them

Need some help. I'm going to buy a XPE and XPG leds and install them into these 2 flash lights. The last Mod I did was installing a Q5 into a light that had a luxeon led. When done it only ran for 10 minutes on a fully charged battery but was very bright.

What do I need to considered before installing the led. Example VF voltage? Amp? Driver?

I think the driver in this light was meant for a cree Q5 but both of the light I bought have generic leds in them.

I may use the existing driver. Any advice would be useful.

Vf is not usually something that you usually get a choice in, you get what you get. You can buy them sorted by forward voltage but it is going to treble the price at least.

An XP-G does prefer a lot of current which the driver probably won't be able to provide - but it should be brighter at a given current than what you are replacing. Definitely worth a try. Heat should be less of an issue with a more efficient LED.

I saw somewhere advertising XP-E R5s recently but this may have been a typo (or lying) - I've not seen anyone offering the XP-E R3 despite its allegedly having been available all year.
