Question Isn't LEP used in street lamps? Why is it used in a flashlight?

[David Magim]

Nitecore released the P35i on Kickstarter,it used of LEP as the main light source of P35i.
But it is understood that LEP is used for street light, right?
I watched their video and it works OK.

It's a type of lighting. There's no particular reason that a type of lighting in some street lights can't be used in some flashlights. Perhaps your question is unclear.

I want to understand how they deal with the heat dissipation of LEP.

Street lights are usually high pressure sodium or metal halide

laser excited phosphorus In the flashlight is lower power. obviously the power is scaled down so there isn’t such heat to be dissipated as there would be in a street lamp.

Many of the street lamps have gone to LED. And thankfully the cities went with the lowest bids and lots of lights are suffering premature failures from UV filters wearing early to PCB going bad.

The main advantage of LEP in a flashlight is that the beam doesn't spread out. So a bright illumination is possible up to a mile from the source. See this article for tested LEP flashlights -- https://1lumen.com/lep-flashlight/

I want to get something out of the way. When we're talking LEP here, is it Light Emitting Plasma (https://www.onelectrontech.com/soli...lasma-lighting-advantages-and-applications/)?

For flashlights, what I found was laser excited phosphor -- see my previous post.
Maybe a case of overused acronym ...

People were mention street lights and that article pertained to them so...

Yeah, overused acronym.

Appreciate it.
