LED technology for highly efficient BLUE light radiation for fluorescence photgraphy
Keldan's proprietary LED array technology provides a high efficiency BLUE radiation with 450nm wavelength. This light is designed to be used for underwater fluorescence photography . A unique feature is the variable power with 5 settings ranging from 25-95 Watt.
Soft 80° beam
The light has a very soft and speckle free beam of 80° in water (110° im air).
The self contained design makes this light very easy to use. There is no need for special mountings for the battery canister.
The included bracket allows easy mounting on standard arm systems like the Ultra Light arms.
Small and lightweight
The design is optimized for very small dimensions and light weight. You do not find any other light for fluorescence on the market which is as small and powerfull than the LUNA 4 BLUE.
The complete set (light, bracket, diffuser) ads only 0.7kg (0.22kg in water) to your gear.
The LED can not break and has almost unlimited lifetime.
Thanks to its overtemperature protection, the light can also be used outside the water.
The LUNA 4 BLUE uses a rechargeable Li-Ion batterypack which offers much higher power density and less weight compared to NiMH batteries. The Li-Ion batterypack also offers better performance in cold water conditions than NiMH batteries do. The batterypack can be easily exchanged within a few seconds.
The wall adapter accepts 110V to 240V AC. Exchangeable adapter plugs allow worldwide use.
An eight stage charge level indicator gives you the charge level while charging or diving.
