"light" 21700 headlamp?

If you hardly use high or turbo, do you really need the extra capacity and weight? 21700 headlamps are heavy which I think is one of the main reasons they’re not common

Yeah the H03 is so good and lightweight compared to almost everything out there it's terribly hard to beat . I cut off the top strap since I wear my headlamps loose around the neck most of the time .When I need to really have light where I'm looking vs. the direction my body is facing It runs fine on my forehead without the top strap .

The Skillhunt H03 and the Boruit D-10's are my combination of choice .both great lights .

I have more expensive headlamps / none of which I like or use more than these . No need for a bigger heavier battery or light ..

I bought a fireflies PL47 G2 about 6 months ago. The first time I used it I was like damn this headlamps heavy compared to my Skilhunt H03 but after using it for awhile it didn’t seem like that big of a difference.Of course it could be that I have a huge melon, so you might have to take that into consideration. Their website says the PL47 G2 weighs 78 grams without the battery, I don’t have a scale to verify though.

No I don’t, that’s why I said it doesn’t make sence to me.

150g. fireflies PL47 with a 21700 light and battery ..no headband

130g. fireflies PL47 with an 18650 " " "

90g. Skillhunt h03 with an 18650 " " "

30g. Skillhunt h03 headband without the top strap (cut it off)

125g. Sofirn/Boruit D-25 with 18650 strap etc ..

So a Boruit D-10 //D-25 and a Skillhunt H03 with top strap are probably the same at 125g.~130g. fully loaded

Have a Fireflies PL47 gen II (with flood optic) on its way looks like a good light time will tell.

later

This one looks promising too. Similar to shilhunt H03RC but only for 15$

Depends on the purpose of the headlamp right ? I mean if you are cave diving or an activity similar which leaves you basically stranded in a dark place for a long duration of time more capacity seems like a relatively low trade off.

I’m a big fan of the pl47 g2. I run it as high as the temperature limit will allow, set at 45C. I get about an hour and a half out of a samsung 50e

The weight doesn’t bother me, I’ve never given it a thought until now.

Normal people mount a flashlight to their gun. We here at BLF mount a gun to our flashlights.

“No such thing too big flashlight”

I like this one with a built in battery pack. It’s really a smart design and I like to use it for my backpacking trips.

I’ve actually been looking for a reasonably lightweight, efficient 21700 anduril light for months. ZL’s H600 is only 85 grams including the battery, and I bet their future 21700 versions will be within 30g of that. The difference between Olight’s 21700 Perun 2 and 18650 Perun 1 is only 40g, which is about the weight of the headlamp strap. If an 18650 light is light enough for you, I don’t think the ~40g difference should be a factor.

I use an H600fc for rock climbing, and it works better than anything else I’ve used (even better after smashing the frosted lens.) On more adventurous climbs where I’m more likely to need a light, I’m usually wearing a helmet anyway. With the headlamp mounted it seems weightless. If someone could somehow mod a Perun 2 with a Lume X1 and a 2700k high CRI led I’d buy it in a heartbeat. The runtimes of a 21700 are definitely worth the 20-40g difference for me. Unfortunately it seems too heavy/clunky to most people, so I’ll probably just get another ZL if they ever come out with one.

I work inside pipelines for a living, so headlamps are the order of the day, mounted to hard hats.
Having the external battery means you can put the light on the front and have the battery on the back as a counter balance, same as if you were wearing NVGs on a combat helmet. In truth, very necessary.

Let us know your thoughts!

Question and comment.

Q: When people say a single cell headlamp is too heavy, what do they mean? Too heavy for what? Your neck or the elastic strap?

Comment: If you have to think too hard about whether it’s necessary it isn’t. If a spare battery and stopping to change out the cell is an option for you, then Wh/kg differences between cell sizes really is a wash in practicality. It’s like the real world difference between 1100 and 1300 lumens… there kinda isn’t one unless you have a stopwatch or a lux meter.

Couldn’t agree more!

A 0.002 lumen moonlight mode would be nice too .

They feel a bit tiresome after a while of having it on your head and the headlamp being extra mass that’s unsecured and clunking against your head when you turn it.

There is a big difference in having a headlamp for a couple of minutes on your forehead then put in on the shelf for shelf queening.

And there is the actual use of a headlamp for a long time.

When you actuality need a headlamp for a long time weight matters a lot to the point you don’t want to use unless constantly repeating in your head that your purchase was such a great deal.

Try to run wearing H30 and H04 ;))

It is safe to say we can agree 100grams is very little weight compared to 200grams on your forehead, again unless you want something of shelf queen headlamp which is fine, many flashlights are shelf queens anyway but the logic is pretty different.

While you can buy a 1.2kg flashlight for being a queen shelf, try buying a 1.2kg headlamp for being a shelf queen, you simply won’t.
