Any flashlight that has Led lenser zoom system

Reverse image search sometimes helps with such affairs.

Terrible? Maybe you meant terrific? I love it! :-))

It's the patent shitstem (and all around it) what needs to expire. It actually is a hurdle to development.

Did some (mostly unfruitful) image searches in AliExpress with the preceeding alibaba torches, but found this:

Fairly cheap torch, may be worth a try. Driver size is a mystery, which given the two cell input (I'm sure you'll want to set some li-ion 14500s in) will need some special driver if worth the hassle.

I dont know anyone that likes the horrible square beam of an LED chip!
LED Lenser managed to pull this off with a perfect round dot in the middle when focused.
I cant wait to their patent expires. Anyone know when its due to expire? I think the life of a patent is 20 years typically, depending on the jurisdiction.
LED lenser have been around since 1993, but doubt they had LED lights until the early 2000’s so probably renamed the company at some point when LED’s came out and probably when they designed their “lenser” focusing.

Shame it only takes AA/14500 size batteries, that does not give you alot of options. You can get more capacity from an 18650 than 2x 14500.
Might be worth grabbing one to mod. I wonder if they make other sized lights?

I do. And I really don’t understand why people hate it so much.

I like TIRs mostly because their efficiency is higher when it matters more - to see far you need more light than to see close.
But they are physically larger, all that I tried so far don’t have as nice flood or intermediate beam (I’ll get a Led Lenser next month). I find both throw beams nice so here’s a draw.
Aspherics have better thermal connection between the LED and the shelf, they also have much more shelf space.
TIRs have shorter focal length and look nice with aux LEDs (though I’m yet to get a zoomie with them).

I’m yet to determine which I like better overall……

LED Lenser is still a TIR lens, its just designed to have the LED slide inside it for focusing.
TIRs are great, but as far as you say about focal length, they come in many different focal lengths.
Just take a look here 1.48€ 27% OFF|10 Teile/satz 20mm 10/30/60/90/120 Grad Convex Optische Glas LED Objektiv Reflektor Kollimator Für LED Licht Lampe Birne E27 MR16 GU10|Objektive| - AliExpress
Im assuming 10 degrees is a more narrow beam and a 90 degree would be alot more floody.

These are non-zooming TIRs. Yes, 10 degree will have narrower than a higher degree one from the same family. But it’s not about a focal length, all TIRs from the same family tend to have it the same, unless manufacturer goeas as far as to optimize them for certain LEDs.

A buddy showed me the Coast G450 light that he picked up from Home Depot. Its the first time I got to look at the Coast adjustable TIR and it had a very nice flood and decent throw. I wish I had taken pictures of the beamshot. Sadly the flashlight uses 6xAA which is a no go, and I want to pick something similar that works with 18650 batteries. I found this thread, and it appears the Led Lenser’s TIR is very similar, if not superior to Coast’s. I’m not a fan of the standard zoomies, but I’d love to find a 1000+ lumen flashlight with Coast or Led Lender’s TIR at a reasonable price.

Same here.
The only other zoom system I’ve seen is the 2 element type seen on some fenix lights.
Does anyone know when led lenses patent expires?

I think this is the patent:
ADVANCED FOCUS US7461960(B2)

Assuming it is a utility patent, then it expires twenty years after filing. So 2026 at the earliest…

Interesting. So we have another 6 years, on the US anyway.

Led lesners, led lenses, led lender's… did you say led losers? :-D Cheap easy joke of course.

Did I say patents are bad? Patents are bad. The whole system needs a root based change. People can't live crazily looking to see if someone else registered an idea in a system, this causes heaps of people, corporations to be chasing patents which, like parasites, live at the expense of others. Those who think this bears no consequences is wrong, karma always hits.

Ideas and knowledge belong to anyone who devises them and anyone which he/she shares it with. This is very easy to understand. Knowledge must be free.

People please trim off any quotes you make, it already looks unnecessarily heavy on a smartphone screen. Thanks. :-)

I haven’t tried a LED Lenser zoomable system flashlight yet, but someone mentioned the YLP Falcon FH5 (2x AA zoomable headlamp) has relatively little loss in lumens while zooming in/out.

I have a Falcon F15 which probably has the same lens as FH5.
It’s partially frosted which reduces throw slightly. But it’s OK. Flashlight build quality is good too. But it’s glued. :frowning: And zooming works slow which is a big deal with a handheld zoomie but not with a headlamp.

Someone messaged me a link to a sale for the LED Lenser MT10 for $39.99:

Mine is on the way and am looking forward to adding it to my collection.

This one is affordable but, just noticed no zoom system.

A tiny bit less than $40 for a P7.2, wonder how modifiable is this torch.

P3R is on a sale here for $24.5 shipped. But as soon as Jan payment reaches my account I’m ordering P3 AFS/P for $40. P3R is much brighter, rechargeable and I suspect it has a metal pill.
The reason is that the P3 AFS/P is already huge for AAA light and P3R is over the line. :confused:

Here’s a thread that can give an overview of it is made!

And a modding thread!
