Deal Details
Found a solid 42% off deal on the Sofirn HS43, bringing it down to $36.53 (reg. $63). Deal Ends April 30th.

Important: Do NOT clip the coupon on the product page. If you do, the promo code might glitch out. Just go straight to checkout and enter code 798765VV to see the $36.53 price. Or just use this Use this Promo Link [amazon.com] to automatically apply the discount.

This is a beast of a work light. Instead of those annoying buttons you have to click ten times, it has a physical rotary dial to change brightness—super handy if you're working with gloves on or just want a simple interface.

Why it's worth it:
  • Dual Light: 3200 lumens for the main light plus a dedicated red light mode for night vision.
  • Battery: Includes a 5000mAh 21700 battery, so the runtime is way better than the smaller 18650 lights.
  • Magnetic: The light pops out of the headband and has a magnetic tailcap. You can stick it to a car hood or a fuse box while you work.
  • Charging: USB-C built-in, so no need for a separate charger.

It's definitely on the heavier side for a headlamp because of the big battery, but for DIY/garage work, it's one of the best setups you can get at this price.

The rotary dial instead of having to click through every dim, strobe, and color setting is nice...I don't know why all the cheap clones think people want "6 functions" that they have to cycle through every time.

But "use 5v charging only" means they might've cheaped out and just attached a USB C port to old/dumb circuitry, meaning phone/laptop chargers may not work. They do show a USB C to C charging cable so maybe I'm wrong...usually ones that only work on 5v chargers have a USB A to C cable.

Yeah I agree 5v ain't that great. The only plus side with that is the battery would last a bit more (Lifetime)

I don't even mind the charge speed itself (5v 2a for 10 watts should take a couple hours I think?) if it means the cell lasts forever instead of dying in a year, it's more the concern that none of my "normal" modern USB C chargers will work and I'll have to find a dedicated low power one vs. being able to plug in anywhere.

Tempted to order one just to find out, and return if needed...

Maybe use an AI to ask that question. But I think the modern charger would adjust to the capacity of the device.

Just make sure and doble check with AI o Google Search. It would be a pain to have just a few connectors to specific items.

Modern chargers do adjust, but look for a pulldown resistor first, apply 5v, then negotiate for highest supported voltage. If a "dumb" device doesn't request higher power, it should get 5v.

But if a manufacturer just connects a USB C port to a Micro USB device, without the resistor, many (all?) chargers ignore it. Not speculation, I've had a couple cheaper devices ignore my Anker etc. chargers, and only work on old A-to-C cables (which send 5v all the time).

That said, I saw comments on a different Sofirn model that "C to C cables work", which I'm taking to mean correct implementation.

Update: Sofirn HS10 (more compact version, 16340 battery) does work with modern laptop/fast chargers (C to C). But it came with an A to C cable.

My wife bought some rechargeable frother, and brought it to me and told me it was dead. It wouldn't recharge for anything I took it apart, and then after asking AI a bit, really old dumb charger, and finally it would charge. It refuse to charge on USB C to USBC for sure

I have the hs41 in a 5000k color variety, and I love it even though there's no red light and there's no convenient rotary dials. I would probably love this.

but I will say that hs41 is on the very limit of the weight that you want strapped to your head, and when I put it on my hard hat the combined weight can feel a bit much. I don't mind it if I just have a cap on, but it needs to be just a smidge lighter. I'm more likely to reach for the hs21
