Flashlight Enthusiast
ma_sha1, I haven't been on in a while but I see you've made a lot of progress over the year. My project has stalled due to funds, but it's not dead. Working on a cost effective injection molding process for the housing. I changed back to a molding design instead of fabricated metal due to electrical safety. I would love to go with carbon fiber layup, but it's about as conductive as metal, so it's not any safer, so I decided on Kevlar. It's not conductive and it's stronger and lighter than fiberglass, and it's not itchy. The prototype is under 10 lbs total (without battery) and consumes 1025 watts total (120v AC or 120v DC) with power supply losses.
Here's a shot of the 75,000 lumen beam. ..
No actual beam shot of the clouds, I didn't take the pic. It's a very uniform circle on the clouds. Looking up at the beam is dizzying. I finally reached my goal of a portable light with the output of the SX-16 searchlight, but with half the power consumption (if you don't mind waiting a minute for start up).
This is with a shallow 9.5" reflector. The lit up trees is all from the stray light which will be better utilized in the beam with the next prototype with a deeper 10.5" reflector with a bit shorter FL. Still will be under 10 lbs, that's a major goal for me. Strange how the stray light on the trees is white but the beam is so blue, but it's all the same light. The clouds reflect white like the trees. I don't understand the blue beam. I run it for about an hour at a time for temp tests, and during that time cars come sneaking up the road with their headlights off. Makes me chuckle.
By the eye, it appears to have same exact throw (and beam color) as the Arctic Spyder 1W laser, which in itself is a pretty insane laser, but with them both on, the 1W laser is dwarfed.
Always use a UV blocking lens! ALWAYS!!! I ran it without for about five minutes thinking such a short time would be ok, and I was wrong. Without ever looking in the direction of the light, the reflected light gave me Arc Eye and I had to go to the optometrist the next day because all I saw was blur. It was quite scary. Fortunately it healed after two weeks with no after effects, but I was lucky. It was my lesson to never take even the slightest chances along the way. There are no short cuts.
