This is your chance to get a Vela One flash at a bargain price. The flash is in perfect condition, but the packaging is damaged.
The Vela One is the fastest flash you can buy. Take pin-sharp photos of supersonic bullets and explosions using a normal SLR.
The pulse width is adjustable between 500ns (1/2,000,000 sec) and 5µs (1/200,000 sec), which is fast enough to freeze a high velocity rifle bullet in flight. This incredibly short pulse means it needs a ridiculously bright flash to achieve a reasonable exposure in that time. The Vela One boasts nine ultra-bright 5000lm chip-on-board LEDs, which are boosted over 2000%, giving peak flux of up to 1 million lumens.
Even at this brightness, the short pulse means it needs to be close to its subject, so it needs to be able to stand up to some punishment. The 25cm (9") square, powder-coated chassis is machined from aluminium, while the LEDs are protected by a 3mm polycarbonate plate (which is removable and washable). There is a tripod mount on all four sides, giving unbeatable flexibility in mounting, and there's no need for a power supply as it runs from the same four AA batteries as your speedlight.
