KELDAN Video 4X 6000 Lumen Underwater Video Light




6000 Lumen, 110 Degree Beam Angle, and 82 CRI in a Compact Professional LED Video Light


The upgrades KELDAN has managed to pull off in this light are staggering. Output is increased by 50%, beam angle 11%, and CRI 17%. Keldan takes performance standard seriously, carefully validating all specifications in an exhaustive quality assurance process. LUNA 4 emits an actual measured 6,000 lumen, not a calculated output.
  • 6,000 Lumen Output
  • 110 Degrees of Usable Beam Angle in Water (90 Deg using FWHM 50 Standard)
  • 82 CRI
  • 5000K Color Temp
  • 200m Depth Rating
  • 45 min Burn Time at 6,000 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
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 this light. The usable beam angle is much wider thanks to a very even and gradual edge falloff.



Battery packs can be easily changed on in the field, supporting long shooting days, and an LED charge indicator provides battery info at a glance. KELDAN LUNA 4X: the performance professionals require.



LUNA 4X 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 mirror less interchangeable lens systems, DSLR cameras, and camcorders. The ultra wide lenses utilized by these systems demand a wide, smooth beam angle, and LUNA 4X delivers. LUNA 4X achieves remarkably accurate color rendition thanks to its even spectral distribution.











LUNA 4X has an impressive list of improvements, and the achievement of this high performance level in such a small light is really amazing.



6,000 Lumen output will certainly be useful, but I'm most excited about the wider beam angle and higher CRI. The wide beam with soft gradual falloff works very well with the fisheye lenses I use on interchangeable lens cameras, eliminating the "head light" style lighting I see with lights that have a simple flat port. The light feels a lot wider in use than the 90 degree tested specification would imply.



82 CRI is really a noticeable improvement in light quality over "cool white" leds, rendering more pleasing reds, oranges and skin tones.
