UTorch SF01 price drop to $6.99

Probably not, didn’t test it because the info i gather says i doesn’t work and i don’t wanna “blow it up” … other think is that i didn’t manage to open the head(meaning didn’t see the driver yet)

I’ve run for a while (minutes) on 16340 without issue. no smoke or LED discoloration. All modes work with brighter levels but can’t say about long-term usage,

Finally tested it with a 14500 and a 16340 they work and they are brighter I estimate around 450 lumen @ 1.32A(tail cap current). I tested it briefly I don’t know how it will handle the extra power and heat…

Thanks for trying them .

0K, so that Utorch SF01 @ GB can take CR123/16340s, AAA/10440s or AA/14500s. From the above comments I can infer it may use a boost/linear hybrid driver. However, does it implements some sort of low voltage warning or cut-off? Piece of shit cake AA/AAAs plus one run and dump CR123s specs cell support tells me it may not, which is a bummer. :|

For the above people sticking li-ions inside beware: boost/linear driver will continue boosting and discharging li-ion/LiFePO4 cells maybe without too much discernible change in output until voltage is down to harmfully low levels, for li-ion cells at least. This is the same crap which happens with shooting range meat cheapass SK68 flashlights. :-D

Cheers ^:)

Ok so why not use only protected batts if unsure what’ll it do and leave the batts with the job of protecting themselves regardless of whatever this driver attempts. Should I try it with a protected 14500 outside in the middle of a concrete pad in a steel bucket? :person_facepalming:

Then again, maybe this particular hybrid driver won’t do that to a protected lion batt. Unprotected IDK. Buy one yourself for $9.99 and report back to us! :slight_smile:

Rechargeable cr123 based cells are an issue because the button top protected ones are too long and the light won’t function without the tailcap loosened a couple turns. If you use a protected cell, use one that is equal in length to a standard store-bought cell.
I sold mine for a few bucks so I don’t have one to test thoroughly but the contact issue is what happened to me. When I swithched from a rcr123a to a regular 123a it worked fine.

Wait a second. Contact issue? If I can run a AA and the tail cap fully tightens then how come ya can’t run a shorter rechargeable cr123 cell? :student:

Also this light can’t work if the tail cap isn’t fully tightened to begin with. Btw I think you meant that the light won’t function WITH the tail cap loosened a couple turns. Which is true. Again, this light must be fully tightened for it to contact the tube and close the circuit anyway.

I sometimes cut a coil or two off tail cap springs if I think there’s excessive/unnecessary pressure on the neg batt anode. On this light if one plans to run AA length size batts it prolly wouldn’t hurt.

When using rcr123/16340/cr123 this flashlight has a fixed holder on the positive end, this holder is larger than the AA so you can push it down, so rechargeable protected cells witch are longer than cr123a may not fit. I test it with my only button top ORB1607 from my OTR U16 flashlight and it works, but this battery are not protected so i don’t recommend using it(this driver will keep draining the batteries, it’s not made for rechargeable li-ion), with my flat top 16340 don’t work(don’t make contact). Other option is using protected 14500, i’m running it with a soshine 14500 protected cell… one disadvantage of the 14500 or AA cells in this flashlight is to be a bit harder to screw the tail cap while pushing down hard at the same time.

See the first post for an even lower price for 11.11

Just ordered a 3-unit combo for USD 9,99 / EUR 9,23 from GB :slight_smile:

Sorry to interrupt your tech-talk, but I just bought this light for $4.99 (€4.45).
Use the coupon code: GBQCSF01N when the light is in the cart.
Had to pay €0.74 for shipping, however.

More info, follow this link to Reddit.

Three SF01’s for $9,99 sounds better to me :wink: Use the 3-units combo offer/promotion, no code needed.

this is a steal, i just order 3 for 10$ and i want to order another 3 :person_facepalming:

This youtube review shows an Enloop Pro being inserted into the flashlight and then being turned on. The review on the SF01 starts at 5:15 and the insertion of the AA battery is at 7:20.

Not the most professional of reviews but at least it shows it working with a RCR123A and an Enloop.

My wife would agree with you. She probably would buy much more of them to save much more money.
I just spent less on 1 light that only made me curious, probably can’t EDC and certainly won’t give away.
I only buy/give away lights that run on primaries if they are to be meant for a keyring or have a vampire driver.
So I don’t throw away anything that is not totally depleted (hmm, almost sounds like I’m a married woman :smiling_imp: )

Arrgghh… 3 XP-G2s for $10… there’s less than 100pcs left. With clip + pouch included and it’s programmable. While still waiting for 2nd batch of Sofirn’s C01… sure, why not? :slight_smile:

I could not resist 3 for $9.99 either. Probably use for stocking stuffers. Has anyone used lithium- ion for any extended time in one of these yet? Might try a protected 14500 in one for giggles.

i gave mine a full run on high mode with lithium battery and it’s not an issue at all.

it gets warm and i would of guess around 45 degrees? (sorry i left my temperature sensor at my parent house)

Thanks for the report on that. I will give mine a try when they come.
