Keldan Video 4X FLUX 10,000 Lumen Underwater Video Light

Based on a smaller housing and four cell battery pack, but featuring the same wide, smooth, even beam that is free from distortions, the upgraded Keldan Video 4X now emits 10000 lumens. Burn time is unchanged, 45 minutes on full power.

This is the ultimate in a travel friendly high-end video lighting and is perfectly matched to camcorders, compact digital and mirrorless interchangeable lens systems in size.

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.

The Video 8X takes advantage of the fixed light head style (as compared to the modular Video 8M) to effectively cool the LED array, allowing for higher output and maximum efficiency in an extremely compact form factor.

Smooth, Even Coverage

To the keen eye of the underwater videographer, the shape and quality of the beam are paramount. The dome of the Video 8X and Video 4X lights allows for a 110 usable beam angle with gradual falloff. There are no hard edges to contend with even with ultra-wide lenses. These lights produce 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.

Interchangeable Battery Packs

Battery packs can be easily changed in the field, supporting long shooting days and short surface intervals. An LED charge indicator provides battery info at a glance.
