Sold/Expired For Sale, 2 stage SF Z57 tailcap

The Surefire Z57, is a click on lock out tailcap is for the executive series of lights, such as E1x / E2x / E2D / E2O.

I am offering my service to mod Z57 into a 2 stage tailcap for use with LED to provide a low / high beam. Currently, I can fixed the Z57 with the following resistor values, 10 ohm,22 ohm, 33 ohm, 47 ohm, 68 ohm and 100 ohm.

For E1L or KL1 on E1 body, (1 cell body)
With 22 ohm resistor, runtime for low beam is about 54~60 hours.
With 68 ohm resistor, runtime for low beam is about 150 hours

For KL4 on E2D body, (2 cell body)
With 22 ohm resistor, runtime for low beam is about 20 hours.

I am selling Brand New Z57 tailcaps with the modification, for US$40 including international shipping.

Edit...

Question is answered in post # 1 :lolsign:

Is this the same as the TrueBlue mod?

Yes

Do they still click on? Or are they push low/high momentary, twist low/high constant, like the McE2s?

This will work with the L4, right?

Can you describe how the tailcap will work after the modification?

i.e. Twist for levels, click on and off or cycl through clicks for high-low-off.

Thanks for the clarification,
MSax

Kam,

I already PM'd and asked that same question and he said YES, it work w/the L4.

Sounds nice

If it the Trueblue mod, then it is a twist on/twist off, click high/click low resistor mod:

After the mod, twist clockwise all the way to activate the low beam, click lightly for momentary high beam or click fully for constant full beam, click fully again to return to low beam, twist counter-clockwise to switch off low beam, further twisting counter-clockwise to lock out.

Hope I have answer all the questions.

Thanks xaman

Do you have a rough estimate of how much light it will put out on low with 10 ohm if you put it on the L4?

Thanks
Kam

I'd like to buy one of these. What would be the estimated runtimes for an L4? Please PM me your paypal details with your reply.

Any way to get: twist on low, twist on all the way to get full, push a little, get low, push hard, get high, or, if in low from the 1st twist, then hitting the button will give you high......... anyways to do that with this tail cap?

hi James, Sorry for the late reply.
All the runtimes test that I had done are using several KL1 with a single cell body. Will do the runtime using my KL4 with a 2 cell body tonight. Let you know the result at a later date.

I had run out of Z57 tailcap for the mod, will PM you my paypal details when I can get some more tailcap from my local dealer. Thank you for your interests.

hi Doug, Sorry for the late reply.

Yes, the mod work in this way. Hit button lightly for momentary high, click button for constant high, click button again to return to constant low. twist off, twist again for lockout.
