Olight 21700 Head Lamp

Is this for real?
I heard that Olight is releasing a new Perun 2, on their Black Friday sale, is this it?

Why did you post that weird members only no contacts available site?

Why not go to olight??????????

https://www.olightstore.com/perun-2.html

The light weighs 161g (OMFG!!!!!)
It runs for 2 mins before going to standard 18650 lumens.
Why would anyone want to carry an extra 100g and for what? 2 mins of turbo?
2170 light are too heavy for the forehead. Maybe a helmet light, but then back to 2 mins.

Not an Olight fan, and I will never buy this unless it’s a super way lower price, but dang it’s purdy. Too bad you effers spoiled me into wanting more than a pretty face.

When I posted this thread, Olight had not released this light yet, and that was the ONLY web site that had posted ANY pictures of it.

Can’t tell if you’re being serious, but it’s been pointed out in other flashlight posts that we can’t help but notice if the runtime at lower levels(280lm) is only 50% longer than the stated runtime for the turbo mode(2000lm), that should raise some red flags for you without doing any kind of research.

If we’re actually getting 2000lm out the front, then we have to assume something like a 30% overhead for the driver and optics. So that’s maybe 2850lm actually being generated by the emitters. If we then look at the LH351D test by Texas Ace we see that the wattage for that would be like 20w for the 3 emitters. You would need a greater than 20Wh cell to get an hour of 2000lm from that, if the thermals didn’t cook everything first(they would). So we see it’s an impossibility for even the Olght with its monstrous weight and 21700(15Wh max), not to mention impossible for an 18650(10-12Wh) or 18350(3Wh).

Nice looking light, I’m a sucker for that orange. Probably no thanks for me though, not impressed by Olight for the price.

Its not just Olight. Now new trend over-weighted headlamps.

What do people use/need headlamps for with 2,000 lumens. Certainly not hiking.

Playing solitaire when the power goes out.

Why not hiking? Just walking on paved roads out in the woods I’m taking advantage of 3000lm to find out WTF just made that noise.

Never enough light when hiking, also 21700 runtimes are superior. Weight its subjective. Its too much for you or not.

If you need more autonomy you can use wired external battery pack mounted on belt or in bag. Lumens are subjective… i don’t need to shine like sun for 12h ;))

Well living in the place where right now sun sets after 3 pm. and rises after about 17 hours has teached me to like lumens and runtimes too. If I keep going north enough then I will see the polar night too where the sun wont rise at all.

With lights its always a trade-off, never cant have everything I wanted. Reminds me of life too.

Hiking to me means a trail in the mountains. I’d like for my eyes to be somewhat dark adapted and I’d like to use no more light than necessary for that reason and so that the battery will last. I can ramp it up a bit for sections that require more light.

Very high lumens is more like trying to make the night like day. Not necessary or even preferable IMO.

Even walking around my yard or neighborhood at night is better with less light. With 2000 lumens you are just drawing attention to yourself and likely disturbing every neighbor around.

Light is a replacement for fear:)

Do you have the freedom to roam around there? Like off the trails and go pretty much anywhere except military training grounds etc.?

Yes, I live in Seattle. We have the Cascade Mountains within a 45 minute drive. There are trails everywhere but especially in the winter where it’s covered with snow you can go anywhere you can get to. There’s also the Olympic Range to the west plus Mt. Rainier.

Finding mountains around here isn’t hard.
