[QUOTE="WayneF, post: 385713, member: 12496"] I would not call that deception. Their video says flash duration of up to two millionth of a second (I don't know how bright that could be?) Their claim is that is faster than a speed light (a couple of orders of magnitude perhaps, my words, not theirs). A speedlight possibly could be made faster, but not sure how it would sell? (we seem to want more power and light from it). What they show is certainly not Daisy BBs. 22 caliber rifles do not go 3000 feet/second either, maybe 1000 to 1200 f/s. And here is a Wikipedia reference (air gun) to air rifle round balls approaching 1000 feet/second in the 17th century: "In the 17th century, air guns, in [URL="http://en.wikipedia.org/wiki/Caliber"]calibers[/URL] .30–.51, were used to hunt big game deer and wild boar. These air rifles were charged using a pump to fill an air reservoir and gave velocities from 650 to 1,000 feet per second (200–300 m/s). They were also used in warfare; the most recognized example being the [URL="http://en.wikipedia.org/wiki/Girandoni_Air_Rifle"]Girandoni Military Repeating Air Rifle[/URL]." We probaby do compression better today? :) I don't see the problem? I have absolutely no interest in this, other than addressed here, but here is more info: [URL]https://www.kickstarter.com/projects/vela/vela-one-the-worlds-first-high-speed-led-flash[/URL] It says one million lumens when run at 20 times rated power (for a short duration). If 1/2,000,000 second duration, I think that would be 1/2 lumen. But (about bullets and GN) see the FAQ at page bottom at [url=http://www.kickstarter.com/projects/vela/vela-one-the-worlds-first-high-speed-led-flash]Vela One - the fastest flash in the world by Vela Labs — Kickstarter[/url] [/QUOTE]
