I recommend you guys buy the Sofirn version. Sofirn just found the issue with their driver that caused it to under perform. My 21700 version makes even less lumens than the 18650 version. Sofirn is sending out free replacement drivers to those who bought the 21700 C8F with the bad drivers. This clone version is still using the old driver so should be making 1,000 lumens less than the Sofirn fixed version. Besides we should support Sofirn for coming up with this excellent design and listening to the BLF for suggestions.

Maybe we can have a Sofirn C8F group buy.


Nobody comments on that, I guess I can assume that UTorch has the inferior driver, right?

I am not really sure if this C8F model is able to see the light. innocent Sofirn is unable to provide support for my GB.

Group buy is confirmed. We need names for at least 150pcs. Our group buy price will be marginally cheaper than C8F. However, you can be rest be assured that Utorch C8F will be the cheapest 3000lm (or one of the cheapest) flashlight to date.

Interested, depending on how much lower the price would be, compared to the Flash Sale coupon price..

It’s already a good deal. Less than $10 for every 1000 lumen. Don’t know if you can find that very often. Be awesome if it were brought down to $25 or so. I would buy a couple for that price.

There will be another price coming in soon. If you are not short of lights, i advise to wait a bit longer. Coupon will definitely be for the first batch of C8F. They are scheduled to deliver by end of this month only.

I heard someone (Jason?) mentioned new Sofirn C8F driver has yet to address under-powered issue. Hope confidence would be reinstate for C8F after it is 100% fixed. If they wish to delay another month, so be it.

Sofirn is supposed to be sending me 2 drivers to fix this issue. Hopefully they will work better once installed. I have 2 so I will post my results for each light before and after the new driver is installed.

It is quite strange. My driver with Sofirn 21700 was only pulling 7.2A and had 2580 lumen. I swapped to a better FET and got 9.3A and 2930 lumen.

I assume the FET swap helped. Testing a couple days later showed output was down to 7.7A and 2450 lumen. This was a head scratcher. I was thinking maybe the edge of the driver was dirty and not making good contact. I cleaned the driver edge and driver cavity and retightened the retaining ring. Then I measured 9.6A and 2930 lumen.

I don’t think it was dirty, I suspect the driver retaining ring is not tightening fully. It seems to tighten to a certain point and stop firmly instead of how a normal ring will continue to tighten as pressure is added.

SKV89 recieved his replacement driver with its new FET and saw no change in output.

So I’m thinking maybe it’s not a FET related issue, but a connection issue with the retaining ring. I plan to add a copper shim or maybe build up some solder on the edge.

I relayed this to Sofirn. I also suggested they swap to heavier led wire. I recently swapped it to 18ga and got 11.5A and 3330 lumen. So that is an easy factory upgrade that can boost output.

Domari Nolo “I Refuse to be Subjugated” (1st Pennsylvania Regiment Flag) https://www.1stcontinentalregiment.org/blank
(Flagguys.com):..and man o man did they ever refuse to be subjugated. These guys were everywhere. They were important in Washington’s siege of Boston. They stayed behind and were the last to leave after covering the main army’s dangerous nick of time retreat from Long Island. They crossed the Delaware with Washington. They were “..at Brandywine, Germantown, Monmouth, and every major skirmish, and battle all the way to Yorktown..” where they fought “the most important part of the siege” according to General Steuben. These guys saw action in every one of the original 13 colonies.
