Please add me to the list.
if i have a 2 lights of the same lux, but one is 2000 lumens, the other 3500 lumens, will the higher lumen light actually put more visible light on a target, at say a 3/4 of a mile, or will it be roughly the same ?
even if they are roughly the same lux?
It will put a bigger spot the same brightness
Please add me to the list.
Please put me on the list as well.
Ok, from 1.3 miles across the lake, this first shot is with my Canon 5D MkIV with a 70-200mm F/2.8L IS lens, zoomed to 200mm. I am putting here full size (jpeg from the camera) so you can see what I saw… there was a white pick-up behind where my brother was standing, he’s in a dark jacket and you can see him against the white truck, right in the middle of the truck, and this is with the light from 1.3 miles away!
This next shot is why my brother was standing over there, I tore the front cover off a magazine and put it on a stand, another tripod held my Canon G1X. Neal shot the magazine cover with the G1X at ISO1600, f/5.6 and 1/4 of a second, lit by the GT from across the lake!
The full size images are 30MP, sorry but it’s for posterity. 
PS: Yes, I know, my brother’s name is Neal. He knows zip about camera’s, amazing he got this. lol
There were no lights at this spot, amazingly enough. They call it a park, there were a couple of picnic tables and the place for about 4 cars to park, no streetlights at all and it was pitch black from across the lake. I had my brother turn on a Sofirn Triple C8 so I could locate him, then I lined up a green laser on this magazine cover, held in a double clamp on the upright post of my tripod. I removed the laser and put the light in it’s place. That’s how I got the centering alignment done.
Obviously, even at 1.3 miles the light is illuminating the white rocky shoreline of the lake and making the pickup visible, even firing up the reflectors on the pickups side markers. Amazing!
Image shack is only showing s 1024 x 682 image 19kb in size.
click the image, it will open in a new window, you can click it again in that window for full resolution 30MP
Only the image from my end is 30MP, the G1X is 14MP I think correction, 12.64MP.
Dale,
That is impressive!
Thanks for the hard work and thanks to your brother.
Later,
Keith
Coyotehawk will add your names to his sign up list. You’ll see your name when he does the next update. It will be sometime mid January when you are emailed with the details of where to go and how to order. (Uses PayPal, btw)
You can also buy 8 of the Samsung 35E batteries for $40 at the same time as you buy the light. No sign up necessary for those. There are plenty of batteries in stock.
Welcome to BLF.
Ps, The group buy is still open, but could close at any time.
Sorry, I need to ask this question. What is the difference between opaque black switch covers vs of translucent black?
Opaque black isn’t transparent, blocks light. Translucent allows the lighted switch to shine through.
Which one does BF GT come with?
I see the image info as such
4,352px × 2,904px (scaled to 872px × 582px)
Looked cold and foggy there, Dale
The GT comes with black cover that let’s some light through.
Similar to this.
.
It is “supposed” to be translucent!
4352 x 2904 = 12638 (12.638MP)
It’s fog season here, but it’ll light up the moon!
It IS translucent…
