And you guys know that I mean when I say bad. Bad as in bad to the bone.
I’m impressed on such a fast 1 sec shutter.
See if you can up the shutter to 1.5” which is 1.4 sec shutter at least on my camera. That will probably be more what you really will see in real life which will only be brighter yet.
Ya, it's bad. I have never owned or made a light that would reach over a mile. The most impressive thing to me is the fact that I was in the city of Tyler, on a Saturday night.
It was cloudy and very damp. I think that's why you see all that haze in the shot at over a mile. Also, these buildings are already lit up. There's building lights, parking area lights and street lights in this area, so it's not dark.
I would love to see this thing somewhere out in the open on a clear night with low humidity and some open targets. I bet it would reach out much farther.
Yippee ki-yay!! That is totally amazing! I totally understand why you'd love to see this bad boy stretch it's legs out in the open country on a moonless night with low humidity and no wind. You'd hit 2 miles is my guess.
That last pic with the tower is mind blowing bright. I loooove it! Now we just have to get you a 10" aspheric lens, one of those 15000 lumens bridgelux arrays Texaspyro talks about, the fan from one of those swamp boats and a 3 kW generator set and about 5 pounds of aluminium heat sink. Then let you have at it!
Seriously though that is a awesome build you've completed. Thank you for sharing this. It is really food for thought!
Nope, but I waited till I saw no helicopters in sight, before I lit up that thing. Don't want some officer with a real serious spotlight lighting up my world.
The N bin I used will do 850-1,000lm at 3.15A. I don't know what it would do at 6A, but now it should be back to it's max, with the solder joint fixed. Possibly it would be hard to read lux due to the light being concentrated thru the aspheric lens? I don't know.
I did the measurement with the head off in my integrating box… I don’t have the sphere set up yet. It does tend to over-estimate lumens at high levels. I suspect it is actually something somewhat over 2000 lumens.
Hmm… I don’t know about the 3000 lumens things, really, but I am not gonna deny it though since I do not have proof.
First of all, I do not deny that this thing is BRIGHT and has Serious Throw, but still have some doubts. As claimed by Old Lumens, this thing can throw up to about 1.376 miles, which can be rounded as about 2.2km, or 2200 meters.
Assume that we define the throw distance by ANSI standard, to only 0.25 lux.
Then the lux at 1m should be (2200/2)^2 = 1,210,000 lux @1m! In other word, 1.21 million candlepower!
As far as I know the legendary DEFT created by saabluster (Michael) has “only” 700k cp. And this is done with overdriven XR-E with 101mm aspherical lens.
