Radical new light
Added 2022-07-23 05:11:09 +0000 UTCIt's rare that I get excited about a new lighting fixture. But this waterproof Cobra light uses a high power blue laser to stimulate phosphor on a spinning disk (it spins for cooling reasons).
It produces a super-sharp point of light that is processed through a very narrow optical path with a gobo wheel with multiple tiny 4mm images on several concentric circles, and the normal subtractive colour system.
This thing slams out a super-intense beam of light that can easily project images on clouds, and yet you can hold your hand in front of it and the beam is cool.
It's a very radical new style of light.

LEP Light Excited Phosphor, it's been getting pretty big in the world of torches. My tiny pocket light can easily shine 600 meters on low
2022-07-27 02:57:18 +0000 UTCoof.. quick internet search returns prices around 10-12k$... holy crap

2022-07-25 17:21:24 +0000 UTCThe purpose of the blue laser is purely to stimulate the phosphor for a bright point source of light.

2022-07-25 13:38:58 +0000 UTCI'm not sure how much these cost.

2022-07-25 13:38:04 +0000 UTCIt is but there's no description of what each light is called/model details... Those at the end are amazing as well! Oh, they're "Ayrton Zonda 9" Amazing!!

2022-07-24 08:44:06 +0000 UTCI want to see. ๐

2022-07-24 07:29:56 +0000 UTCNote: Some new high end DLP video projectors use laser arrays and multiple phosphor wheels in there light engines. But different phosphor's on each wheel for different colours rather that the typical colour wheel.

2022-07-24 06:38:55 +0000 UTC@Charles Hahaha he should, just cleaning, not shorting out laser diodes to find out the voltage drop across each of them, and definitely not taking that phosphor wheel out for a jolly good clean ๐

2022-07-24 06:32:00 +0000 UTCThat video's fantastic.

2022-07-24 03:39:09 +0000 UTCFascinating. You should tear one down to "clean" it and just so happen to film yourself doing so :) Nah, we don't want Clive to get in trouble.

2022-07-24 03:36:23 +0000 UTCOoooh! I think I just came a little bit..... They are beautiful fixtures, Anyone want to check them out, Search Youtube: l9Ti0qYhtbk 4:20.

2022-07-24 01:13:04 +0000 UTCVery interesting. I'm hoping to see a video of this soon. I wonder if you'll be able to block the laser from hitting the phosphor disk so that we can see how fast it spins. Would be interesting to shine a UV light on the phosphor disk too.

2022-07-23 22:33:41 +0000 UTCThat's what I would assume too. I wonder if it's just the lens doing all of the collimating? It might be able to keep a relatively narrow beam due to the face that the light source is so small (a bright glowing dot of phosphor)
Dan Coulson
2022-07-23 22:32:20 +0000 UTCI'm probably ignorant. Laser light is collimated, but once it hits a fluourescent surface, isn't that lost?

2022-07-23 21:44:05 +0000 UTCIs that from the Dollar (pound) store or Poundland?
2022-07-23 21:38:56 +0000 UTCAmazing. Do they come in pink too?
