Amazon Deal Alerts & Discussion Thread

I put a fresh charged yellow 18650 at 4.16v 2 days ago.
I used the light for about 2 mins total on low and I just checked the cell it reads 4.07, that’s not good right?

Is there parasitic drain using 3 AAA?

In theory the 3 AAA's should have bout the same parasitic drain. 4.16 down to 4.07 in 2 days is some significant drain. I'll measure it later at home.

Sounds pretty normal to me - voltage will drop fairly quickly initially.

Take another fully charged cell, and check its voltage after 2 days. I bet you’ll see it dropped, even if you didn’t use it.

Parasitic drain is easily measurable, least for me. I got 2 meters that will do it. I'll check it out - shouldn't have to wait for 2 days.

The code just refreshed. :partying_face:

Ordered one, thanks. :beer:

I measured 38 uA parasitic drain, which is pretty low. So maybe Pete above is correct - that voltage drop is normal for this drain, or yours has a higher drain, or that yellow 18650 is not so good? Maybe you can look at a discharge curve and see how many amps it would take for that voltage drop. Voltage drop is not linear so have to look at 4.16 down to 4.07.

My AmeriTop flood light came in yesterday. Hope to install it tomorrow.

Just checked voltage it’s at EDIT: 4.06 this is as much as I can do.
The cell had 1 charger on it.
Seems ok, I guess.

I'd run away at 4.63V!

Edit…thanks :disguised_face:

Both NW and CW versions of the Wowtac A2S headlamp are $23.99 (compared to the normal 29.99 price), which was awesome to find since I’ve been eyeing this model for a while now.

Banggood has the Astrolux FT03 SST40-W for 33.99 US right now. If you don’t have one, you need one. Best thrower bang for the buck ever…. Sorry, I missed seeing the word Amazon when I posted this, but I am going to just let it stay because it is a good deal.

Thanks. I ended up ordering one even though not amazon.

I ordered 2 at that price, so when I finally receive them a month or 2 from now, it will be a good day. I am convinced they use very old runners on land, and swimmers in the water. That is the same for all shipments from China though. It is not a service for the impatient. I often even forget about the order by the time it gets here, but the savings on items are just too great at times in spite of the turtle shipping speed. By the way, that Astrolux light can more than match lights that cost 3 times as much. I might even get brave and de-dome one of them.

High quality cells like Samsung 25r or 30q will hold voltage better than less expensive cells. All will self discharge some though. I never really feel comfortable if I do not really know what cell is really under a wrap…especially for vaping or headlights. I also prefer charging the batteries in high quality chargers. I really do not know how they get away with the extreme exaggeration they put on some battery wraps considering the danger. I appreciate a company that does not seem to inflate the mah and current ratings of their batteries.

It depends on the way I will use the light whether or not I like a magnet…some like the nicron n7 with the swivel head, are great for using under the hood of a car. For an EDC light I agree with not liking the magnet, but when you have a lot of lights to choose from every day, a few with magnets are OK.

Hey Lightbringer. Does the A7P only have 2 modes? 65 lumens and 200 lumens? If yes, I would have to pass, even though it's now listed at $7.29.

Yeh, l/h/l/h/l/h/… simple enough.

Thanks for the confirmation. 65 lumens is way too high for a low mode for my purposes, especially in a penlight.

Personally, I don’t think low is 65lm. Maybe on a fresh out of the package alkaleak or something, but…

No AAA eneloops, no fresh AAAs, as I typically just burn down alkaleaks that are already losing their oomf on mum’s craplights, but mine looks like 10lm on low and maybe 65lm on high. Frankly, that’s all I wanted.

Anyone wanna throw a coupla new alkies at me and I’ll put it to a better test. :laughing: As it is, I only get hand-me-downs.

Yeah, it’s odd. All the AAA lights I got, that’s all I use ’em for.
