Quark X 123^2 17670 compatible?

I was just wondering if replacing the 2 CR123 cells with one 17670 will be ok voltage wise for my Quark 1232​ "X" . I know some will be destroyed when you overdrive them so I wanted to make sure before I did it. Thanks

All I ran in my Quark 123x2 was a single 17670 when I had it ,snug fit though. I works fine go for it.

i dont think your going to be even close to overdriving it. the 17670's are 4.2 volt max, and your Quark should be 3.0 to 9.0 volt head.

• Powered by: 2 CR123A batteries (included)
• LED Emitter: Premium Cree XM-L
• Voltage range: 3.0V ~ 9.0V
• Dimensions

3,0 to 9.0 means what it says. You can run 1 17670 in there or even 2 rcr123's. With an AW17670 you might have to take the wrapper off. This means the white part, NOT THE BLACK PART. The Black part is a seal that wraps around the metal part of the battery. If you get an AW, which you probably should, they have a white sticker that is affixed to this black wrapper. Run it without fear, it wont hurt the light.

Some quarks run in the .9-3.9 range. These ones are incompatible with li-ion rechargeable batteries and are intended to run 2xAA, or 1 CR123's.

Actually The low voltage Quark heads WILL run on a single Li-Ion cell, I do it all the time.

Might effect their longevity no?

Ok thanks for your replies. I was pretty sure it would work but I thought I would check and not ruin the new light I plan on using AW cells and the 4sevens charger. Sorry I posted in the wrong section

I think they are rated to 4.2V and should do fine. I've used one of the early ones on li-ions for a few years now with no issues.

Here are the specs of the OP's light pulled from 4sevens.

Description:

The Quark "X" series have received a powerful upgrade - CREE's latest XM-L emitters! The XM-L puts out even more lumens in a wider area, reducing the tunnel-vision effect from a concentrated hotspot.
Features
Power: Two AA Batteries (0.9V~4.2V total)
Output: Maximum - 280 lumens; Moonlight - 0.3 lumens
Runtime: Maximum - 0.8 hours; Moonlight - 15 days
Strobe: Strobe, S.O.S., and Beacon flash modes
Specifications

• Powered by: 2 AA batteries (included)
• LED Emitter: Premium Cree XM-L
• Voltage range: 0.9V ~ 4.2V
• Dimensions
  Length: 5.8 inches
  Diameter: 0.86 inches
  Weight: 2.2 ounces​

Have you had a chance to pick these batteries up and compare performance between them and the 123's?

so one could conceivably plop a low voltage head onto a double cr123 body and use a 17670 for maximum runtime?
