HIGH DEFINITION VIDEOGRAPHY UNDERWATER
Professional LED Underwater Video Lights
With the advent of affordable high definition video cameras and particularly the new Video DSLRs (e.g. Canon 5D3 and the Panasonic GH2) that have interchangeable lenses from macro to fisheye, underwater cinematographers now have a requirement for compact, high power video lights with a very wide beam angle...that can also be used for still photography on the same dive.
After intensive research, development and field testing HDVSEATEK have released the SEASTAR LED 4000 underwater video light.
Our aim was to provide a video light that would perform as well as any other true 4000 Lumen light currently on the market, but at a more affordable price (see below).
When comparing different 4000 Lumen video lights be sure that the lights are genuinely specified at an angle of 120 degrees. A product called "4000 Lumens" actually provides much less total luminosity if it's beam angle is only 80 degees or so.

The Seastar LED 4000 now has a fully automatic THERMAL SAFETY cut-out switch. If the unit is used out of the water it will cut-out before the LED's can be damaged by excessive temperature. Normal function resumes as soon as the temperature drops to safe level.
Using powerful video lights helps to reduce the need for constant White Balance acquisition and it's a far better way to bring out the natural colors of subjects at depth than using color compensating filters. Video lighting also opens many more possibilities for shooting in caves, wrecks, vibrant colorful macro and at night.

A UNIQUE FEATURE THAT THE EXPERIENCED USER WILL APPRECIATE:
REMOTE LOCATION REDUNDANCY
The LED Control Electronics are INTEGRATED INTO THE BATTERY
This means that in the event of a problem, simply insert a new battery pack into the separately watertight battery compartment and all electronics are replaced. Thus the user not only has the safety and convenience of easily interchangeable batteries...but has unrivaled reliability in remote diving destinations. The LED light head is semi-permanently sealed and should never require user attention.
Using a VideoDSLR (like the Canon 5D2 or Canon 7D)?
There is no longer a need to take video lights and strobes on the same dive since the SEASTAR LED 4000 provides plenty of daylight balanced illumination for both requirements. Same illumination as an INON Z-240...continously!
HDVSEATEK designed the Seastar LED 4000 to perform as well as any other true 4000 Lumen light currently on the market, but at a more affordable price. With current LED emitter technology 4000 Lumens is the "sweet spot" in terms of the balance of Video Light size; Lumen/watt efficiency; Kelvin color temperature; Chromaticity; and high CRI.
We considered many alternative manufacturers and decided that only the KELDAN Luna was worth making a meaningful comparison with.
KELDAN Luna 8 LA-V CRI vs Seastar LED 4000
Both lights are similar in size and weight.
SEASTAR LED 4000 "on" Keldan Luna "on"
Both lights fully charged and set to Full Output. Beam angle and Lumen output is very similar (LED 4000 slightly brighter & wider). Camera WB was set to "Daylight"...the Keldan has a slightly warmer than daylight Color Temp. KELDAN rate their light as 4500 Lumens @ 90 degrees beam angle, 5000 Kelvin.
