COURUI DO1 'Big Head' (Black/GRAY NOW AVAILABLE) $29.99 @ Gearbest ( use coupon: gbcourui) A long-throw modder's light!

Exactly. its such a versatile FW I will NEVER use any of the AVR momentary FW’s again, there’s no reason to, UFLC does everything you can possible want. Now that we have it written in C on the tiny little 10F322 this is my go to FW for any momentary light (any my go to drivers since there is also not clicky FW for the 10F)

Oh BTW the UFLC has code for THERMAL turbo regulation!

If there was a writeup on this firmware I guess I missed it. Link me?

All FW related info and video demo’s can be found in my BLF _PIC driver thread and have been updated as of just now, there is no thread specifically on just the code.

I’m still on the lookout for the gray version!

After a couple of days of delays, the gray version’s sku will be posted within today in GB’s website. Stay tuned.

Hi guys,

So sorry for the delay of the gray version, here is one contrast pic for the black and gray, and we will post the sku of gray version on our site later :wink:

dang i should really buy the grey, i am really digging the color.

The gray option shows and works for me, but the promo code does not work for the gray version -- only works for the black version. Needs to be fixed... ?

OK it has the Gray box now.

Thanks

Yeah, you are correct, it does not work now. The gray has just been uploaded about an hour ago. It’s almost 9 in the evening Shenzhen-time now I don’t know if anyone at Gearbest can still fix it.

Sweeet!!!! Just waiting for the coupon code to work!

No prob - I'll wait. Ordering a gray COURUI and a C108S for $14.35 on a timed promo, and using up my pts for another $1 and change... Smile

@ Tom E

Thanks for posting about the glitch about the non-acceptance of the coupon code on the gray version.

Although I have just sent a pm to CSgearbest, I’m not confident it can be fixed now as it’s already 9:13 in the evening, Shenzhen.

Tomorrow then.

Finally. So glad I waited for gray, much better looker IMO.

Any holster recommendation for this light?

Hi guys,

Thanks for your support again!

The coupon code for the gray version does not work now, because the one we got yesterday is a sample for testing, not the batch supply, it will be available for ordering in a few days, I will update on this thread. I’m really sorry for this inconvenience :expressionless:

Announcement to date:

Oct. 16, 2014—-there has been a mix-up regarding the strobe. It is hidden in both color versions.

As quoted in this review in the op:
