link of convoy L4:

and remote switch is being designed

A remote switch…makes me wonder how long one would last as a weaponlight.

This leads me to two questions:

1.) Can the L4’s driver take 8.4v?

2.) When is Richard going to start stocking these tubes too? XD

Sweet! Nice looking extension…very important to me that it matches the original design of the light and y’all have done that very well.

Big High Five on a job well done!

yes ,fit

1.)yes,right
2.)sorry , i dont understand

Very nice, I did not know that the Convoy L4s could run on 8.4V! Are they significantly brighter or does the driver not see any improvement with two 18650s?

output current is the same

Is there a BLF discount for the extensions? And paypal?

And it doesn’t happen to be able to take 3x18650 does it?

3*186650 is not allowed,7% off,my paypal: 353981950@qq.com

Love that is matches exactly.

Does the extension fit other Convoy lights like the M1 or M2?

no

Simon, can I order one of the tubes by sending you paypal or do I need to place the order on your site, then send you the payment?

my paypal: 353981950@qq.com
you can transfer money directly

Looks like its perfect. I knew the driver could take 8.4v but only thought two small cells might be used in pinch.

I’d like one. Is this info correct?

5.27 USD - BLF discount (7%) = 4.90 USD for one L4 extension
Free Shipping to USA, MA?

Then I can send a payment of 4.90 USD for the L4 extension to your paypal: 353981950@qq.com with my shipping address mentioned.

right

Payment sent to your Paypal for one L4 extension!

Thanks very much!

So what is the advantage of using the extension tube ? Since its only serial connection it shouldn’t increase the runtime ? Its only if you replace the XM-L with higher voltage LEDs ?
