Keldan Video 4X Flux 7,000 Lumen Compact Video Light

This product has been discontinued and replaced by the Keldan Video 4K 9,000 Lumen Light.

The Keldan Video 4X Flux 7,000 lumen compact underwater video light is the ultimate video lighting solution for today's hybrid imaging systems.  Thanks to its compact form factor, the light is perfectly matched in size with mirrorless interchangeable lens systems, DSLR cameras, and camcorders.  The ultra wide lenses utilized by these systems demand a wide, smooth beam angle, and Video 4X delivers.  Video 4X Flux achieves remarkably accurate color rendition thanks to its even spectral distribution.

• 45 min Burn Time at 7,000 Lumen, 180 min Burn Time at 1,700 Lumen
• Extreme Efficiency from Custom Reflector and Dome Lens
• Magnetic Power Switch
• Intelligent Lithium Ion Battery with LED Status Indicator

Tested Specifications

Where other light manufacturers might use an LED (or 2) that claims it can achieve this kind of output, KELDAN delivers it.  Actual output is measured at operating temperatures in real world conditions.

This kind of obsession with accuracy is part of the reason that KELDAN lights are known as the best underwater video lights available.  Performance specifications aren't calculated, or read from an LED vendor's catalog, they are tested in real world operation.

Reflectors

To the keen eye of the underwater videographer, the shape and quality of the beam is paramount. The dome of the Video 4X allows for a 110º usable beam angle with gradual falloff. There are no hard edges to contend with even with ultra wide lenses. With a solid spectral distribution that does not miss out on important colors, this light produces a beautiful beam that is ideal for underwater film-making.

Beam angle in water when measured using the FWHM standard of 50% intensity is 90 degrees, but that doesn't accurately represent the beam pattern of these lights. The usable beam angle is much wider thanks to a very even and gradual edge falloff. 

Batteries

Battery packs can be easily changed in the field, supporting long shooting days, and an LED charge indicator provides battery info at a glance. Run time is from 45 minutes to over two hours.
