Now that you have signed up and purchased the light you wanted, delete all traces of massdrop from your computer, unsubscribe from their mailing list, and block all incomming emails!!!
Your wallet will thank you! You have been warned
Lol, I signed up about two months ago and they keep throwing these deals at me…I am too weak and I can’t say no, it’s costing me quite a few pennies. I have avoided the Olight S1 craze for so long, everyone else is buying them, then a rose gold s1 pops up in an email from massdrop for $45……yes please take my money! I couldn’t check out fast enough.
I would guess that 3 HI’s would be in the 1300-1400 lumen territory. Remember that it’s an aluminum mcpcb and proprietary to the optic, the placement isn’t the same as with a Carclo optic so a copper Noctigon can’t be slipped in.
So, XP-L HI’s on Al wouldn’t net much over XP-G2’s but might do it at a cooler temperature. If I’d had 4 matching HI’s I would have found out…
Vinh is claiming to achieve 1253 from the 18650 variant, my little quad PT-16 is doing 1180 from a 16340, so there’s just not a lot to be gained in this one apparently. I guess it’s time to squeeze an FET driver in and find out what’s shakin…
I stripped the driver, piggybacked in a 15mm FET driver with ToyKeepers 64 level ramping firmware. This was not easy. I probably screwed it up in the end but at the moment it’s working. With the partially used little 16340 I saw a first read of 1359.3 lumens from the XP-G2 S4 2B Quad.
This PT-16 has a different button retaining ring than the newer PT-10. I unscrewed it and found a silicone button with metal insert that is fitted into a groove inside the recess, it’s well thought out, as waterproof as possible, and it works. I don’t know if the new one unscrews or not, it doesn’t have the 1/3 circle clip cutouts in the retaining ring around the button like this PT-16 does.
Cell charging, I’ll get a full charge readout when it’s done.
Same exact light, even the same cell it’s shipped with. I didn’t know they were affiliated, learn something new every day! lol
Edit: TexasShooter, been looking at that. I think it has room and feel pretty sure that a Purple IMR18350 would deliver more current. Have to look at the tube now and see if I can keep the on-board charging system or if it needs to go.
CooYoo is their Asian logo and MecArmy is their North American/European market logo. Just changing the filters”location” changes the products names. It’s mentioned on CPF a little while ago.
Removed the charger, bored the tube, made an insulated spacer with Delrin and brass. Purple Efest IMR18350 does a rested 6.01A and 1907.85 out the front… cell measured 4.15V so I’ll charge it up and see where max peaks.
Last night I measured 8.39 lumens at the bottom end. So there’s 64 stop points between 8 and 1900 lumens. How sweet is that?
Edit: Fresh off the charger, the little Purple Efest 18350 makes 2187.3 lumens on top, 8.59 lumens on bottom. I can live with that.
Actually, 2187 out the front on a fresh cell. It’s no longer regulated so output will drop with the cell’s discharge.
I have a little battery back-up pack from GearBest called a Mi (Xiomi) that has 3 18650’s from Samsung or Panasonic, all Texas Instruments components… nice little phone charger or back-up. I used the charger out of the PT-16 with this pack and charged a Windyfire 14500 to exactly 4.20V just a few minutes ago. I’ll carry this with the pack as a very small and accurate battery charger, with green/red indicator lights. As an added benefit, the Mi turns off when the cell is charged, so it is pretty safe as well in this combination. (I removed the springs and soldered wire leads with magnets on the ends, makes it easy to charge a cell off this pack)
It no longer has springs, of any kind. Originally it had a spring between the charger and positive end of cell, another on the opposite side of the charger to contact the driver positive contact, which is a thin brass disc.
Now I have the cell fitted between a brass spacer that is adjusted with the threaded white plastic cover that once allowed the red/green charge indicator lights to show.
Dale, just checking, did you do runtime with the 16340 and 18350? I’m just thinking since it comes with that awesome small form factor, might be good to keep to that form but with your awesome 1493 OTF lums to wow friends instead of ramping up to almost 18650 form, where most torches congregate.
That said, duration might be a whole PITA experience.
