Gun Lighting; Laser Excited Phosphor (LEP).
#1
For those interested...

Here is new technology laser excited phosphor (LEP) lighting adapted to shooting. LEP permits narrow, concentrated beams of light in a light-weight/compact size. This is something conventional LED's and hand-help spotlights struggle to do because either their beam is too wide or they are too bulky to weapon-mount. For long range searching and shooting it works. It's a blue laser fired through a layer of phosphor that turns it into white light.

It's expensive, and so far hasn't recoiled itself into pieces - fingers crossed. You need a square mount that co-witnesses the light to the scope axis. The beam is 3 degrees. I am using a 1" Leupold scope ring on top of the scope. No reason why it can't work with a handguard.

It is rated eye-safe but at close range you can't look into it. Reflection off gunsmoke is also fierce but it clears as quickly as the smoke. On firing the scope instantly white's-out but is clear again a couple of seconds later. Straight ON/OFF, no intermediate modes. You can see bullet holes in paper at 100 for night practise.

This range only goes to 400M so I'm not sure how much further it can be used. For catching the reflection off animal eyes in the distance it works fine.

Also uses latest flashlight battery technology. The single Li-ion is a 21700 which in a 1" tube is the largest battery for the available diameter (longer run times). Recharging is directly into the torch via a USB-C cable. There's a ring-cover with O-rings that unscrews to reveal the charging port. Screw back up to make it waterproof.


There are only a couple of flashlight types using LEP on the market ATM. The one I am, using is by Acebeam: the W10 Gen II. Weltool is the other brand retailing an LEP.

Interesting product, thanks for the heads up!
For some reason they don't trust the average person to own one.

Thanks for posting, interesting design!

Interesting. I’d rather see a value improvement on the thermal or night vision side than brighter lights. That gear is just plain expensive.

At the risk of thread drift, I will say I’m not enthused about this tech in automotive headlights. I know, I know...it’s already out there.

Just like auto high beams (a truly horrible idea), this will just lead to more clueless Mr Magoo drivers running around with high beams on, blinding everyone on the road.

I still want one

To be honest I don't trust the general public either. Always someone who stuffs it up for the rest of us. Laser pointers above 1mw are now import-banned where I live - Thanks to idiots shining them at aircraft.

You can access LEP flashlights, it's just the Chinese marketing department trying to hype it up. They'll take anyone's money. Can't see the military being too interested in this, unless it's for intimidating people or as a close range pointer. PEQ15's already do this.

Battery Junction has W10's in stock however I understand Acebeam have stopped making the larger W30's for some reason (still available if you look around).

Neat stuff Klem. How hot does it get in use? Also does the run time match the claimed 3.5 hours?

FR,

After an hour and 10mins of constant ON last night I switched it off. It was dropping in brightness and I thought it was because the battery was running out. After turning it off and letting it cool for 20 minutes it was back up to full brightness. I went looking for more info and found a review on Candlepower.com. The review is the early lower-output model but the graphs show how an uncooled LEP drops in output fairly quickly, irrespective of power. When he puts a fan on the torch the output stays brighter for longer.

Seems the phosphor layer has to be kept cool to work efficiently. Not suited for long uninterrupted sessions.

More photos, this time the 400M steel with the LEP and against a 75W HID hand-held spotlight with 240mm reflector. You can see the 400M target better including trees behind the mound and wider field of view with the spotty but that's to be expected. Obviously can't weapon mount the spotlight. Need a power source as well.

The target frame at 100 is in the way of the 400M gong but you get the picture.

Forgot to add...it gets warm to the touch, especially round the front, but not hot. You can still hold it with bare hands after it warms up.
