Not real sure on the run time. My gut says over 12 hours on medium. I use it for perhaps an hour or so a night. Frequently I use it on low but lately I have been using it more on medium. I know I typically go weeks between charging it. However, I usually have a 30Q or even a 3500 mAh battery in it. Haven’t used the built in charging since I got it and just did that to confirm that it works and terminates properly. It does.
Just pulled an old Tenergy 2600 mAh that I put in several days ago. Battery was still at 3.9V and at that age IIRC, its down to about 2000 mAh maybe 2200. So, weeks to perhaps a month in my typical usage. I did just do some projects and my wife used it for an hour or so on High resulting in the last charge only lasting a few days. Hope that helps.
hm…im most likely gonna be using it on high, so if i can get like a week out of it, then im happy, i usually only walk him at night for like 30 mins or so…
Oh, right. Regulation is the other wish-list item, but somehow while working on things I never really notice the dimming until it shuts off or just before then when the battery indicator LED is flashing red. I’m happy that it has low voltage protection.
Sometimes I put it on turbo, stick the magnet to a surface, and forget about it until it shuts off.
Yeah, the more flashlights/headlamps I try, I’m finding that this is really a differentiator. It’s why some headlamps/lights are more expensive: better drivers.
The Manker E03H headlamp and inexpensive Sofirn C01S are regulated, IIRC, so the regulated lights are not always more expensive.
Ironically, because the regulation on the E03H keeps the light at one of the (high, medium, low) levels, the drops are very jarring as the battery depletes, while I don’t notice the slow decline on the unregulated SP40.
Thanks for including all the details. It makes a difference for someone who’s never done it before.
In addition to sourcing the emitter, I would need to get some solder paste (most seem to have 1-2 year shelf life and suggest keeping refrigerated) and decide on a pan to sacrifice for this purpose. Sooner or later I just know I have to try this…
significantly, in every almost case. the only time we get some perks is if they listed a new product in USD, but we buy it in CAD. thats about it. lol, we have less selection, higher prices. such a scam
Wow, $32 with 15% off? That’s a pretty legit deal. If I didn’t already own it, I’d be all over that. I didn’t even realize they had it on their Amazon store. You could do much worse for $28 IMHO.
