I heard someone talking about light emitting plasma flashlights - not the laser LEP ones - but Iām not sure if itās a real thing. I was thinking today too how nice it would be to have some sort of light making technology that doesnāt generate nearly as much heat as LED
Uhhā¦ not really sure. I do have a Firefoxes FF5 HID and itās awesome.
I just saw that Sanwu came out with a new laser with a dimmer switch. Are you guys into lasers? If you got the blue you should be able to add a phosphor lens to make a white beam
Short arc bulbs are filled with a gas like xenon or mercury or others, and the high voltage electric arc that forms creates plasma, which is what makes light.
Also if you look at the list you will see that there are several LEP lights, which do use a laser and a phosphor to create high intensity white light
LEP = laser excited phosphor
The Maxabeam G3 is the farthest throwing short arc flashlight you can buy, they show up on the used market often.
HID is a type of arc lamp too, just not as intense as xenon bulbs.
Thatās 63km beam distance
There are some lasers that can do half of that, like https://www.wickedlasers.com/krypton
If you put four of them together theoretically that would double the beam distance to 68km.
Ha wow thatās crazy. Do you have the formula you used to calculate that handy? I have the Wicked Arctic blue (1.2 watt) - wish Iād bought the green before they stopped shipping to US. I have a 1.6 watt green from Sanwu thatās pretty wicked with the beam expander lens
Most measurements people use in this forum are based on the ANSI FL1 standards. Light energy or photons obviously can travel forever, assuming they donāt hit anything. So to create a standard distance to compare beams, we measure out until the intensity drops to 0.25 lux.
You can basically measure a lights intensity at a certain distance and then calculate itās intensity at 1 meter. From there you can calculate a ārated distanceā.
Itās talked about here in the forum, just try searching for ANSI FL1.
