World's finest underwater lighting equipment.

Overview

KELDAN is a Swiss manufacturer of the highest quality lighting equipment.

We are specialized in manufacturing ultra compact, self-contained video lights which are carefully designed for optimized photometric specifications. Our lights have the highest luminous flux, smooth beam pattern without hot spots, outstanding high color rendering and a color temperature which precisely matches daylight.

We sell what we promise: all photometric specifications are verified in our own lab. The batterypacks include a charge level indicator and are designed for easy exchange within seconds.

For best colors under water we offer a range of ambient light filters for the video lights and special spectrum filter for the camera.

For recreational and professional diving we offer ultra compact, rugged LED lights with very high luminous flux and unique features like variable power, exchangeable Li-Ion batterypacks, charge level indicator, LED safety light and others.

All our lights are factory tested to 200m depth.

  


  Products

  • Video 24XR 45000lm CRI86
    45'000 lumen Remote Controllable LED video light for professional applications

    - Ready for wireless Remote Control RC1
    - 45'000 lumen, 5'600 kelvin
    - 11-360 watt LED power
    - Burntime 40 minutes to 20 hours
    - Maximum Depth 200m...

  • Ready for wireless Remote Control

    The Video 24XR light is ready for our wireless Remote Control RC1.

    LED technology with outstanding efficiency

    The Video 24XR is equipped with a LED of the latest generation with a color temperature of 5600 Kelvin. The spectral power distibution is very even, resulting a color rendering index of 86 CRI (Ra). A unique feature is the variable power with 9 settings ranging from 11 - 360 Watt and the optional wireless long range Remote control.

    Soft 110° beam

    The light uses a carefully designed reflector and a dome lens to achieve a very wide and smooth beam without any speckles or hot spots. Beam angle (full width, half maximum) is 110° in water (120° in air).

    Self-contained

    The self contained design makes this light very easy to use. There is no need for special mountings for a separate battery canister. The included bracket with ball allows easy mounting on standard arm systems.

    Lightweight in water

    The design is optimized for minimal negative buoyancy in water. The complete set is only 0.5kg negative. A foam bracket is available as accessory to further reduce the negative buoyancy to only 0.3kg.

    Tough Design

    The LED can not break and has almost unlimited lifetime. The integrated overtemperature protection allows safe use of the light in air.  The protection circuit controls the housing temperature and the power will be limited to keep the temperature within an acceptable range.

    Li-Ion Battery

    The light is powered by 3 batteries of 99Wh each. They are mounted in a battery tray to make a single, easy to use 297Wh battery. The battery tray can be easily exchanged within a few seconds.  For save airline transport, the three batteries can be easily removed from the battery tray and transported individually to meet the requirement of a maximum allowed capacity of 100Wh per battery. 
    The charger accepts 110V to 240V AC.

    Charge Display on the rear side

    An eight stage bar indicator gives you a quick overview of the available charge. The 3 digit display shows the remaing charge time and the remaining discharge time in minutes.

  • Ready for wireless Remote Control

    The Video 8XR light is ready for our wireless Remote Control RC1.

    LED technology with outstanding efficiency

    The Video 8XR 20000 lm CRI 86 is equipped with a LED of the latest generation with a color temperature of 5600 Kelvin. The spectral power distribution is very even, resulting in a color rendering index of 86 CRI (Ra). A unique feature is the variable power with 9 settings with a brightness range of 1:80.

    Soft 110° beam

    The light has a very soft and speckle free beam of 110° in water (120° in air).

    Self-contained

    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 with ball mount allows easy mounting on standard arm systems.

    Small and lightweight

    The design is optimized for very small dimensions and light weight. The complete set ads only 0.87kg (0.30kg in water) to your gear.

    Tough Design

    The LED can not break and has almost unlimited lifetime. The integrated overtemperature protection allows safe use of the light in air. The protection circuit controls the housing temperature and the power will be limited to keep the temperature within a safe range.

    Travel Safe Li-Ion Battery

    The battery passed successfully the mandatory UN38.3 safety test as required by IATA and it is therefore certified for air transport. The capacity of this battery is below the maximum allowed capacity of 100Wh. It contains an integrated protection circuit against harmful conditions like over discharge, deep discharge, over current and short circuit. 

    Charge Display

    The green charge level indicator displays the available relative charge. The two digit display shows the remaining time. While the battery is discharging, the display shows the remaining runtime in minutes (e.g.”18” = 18 minutes). When connected to the charger, the display shows the remaining charge time in units of 10 minutes (e.g.”18” = 180 minutes).

  • Video 8XR Ambient 18000lm
    Extremely small and lightweight, 18'000 lumen LED Ambient video light

    - 18'000 lumen
    - Unique LED that emits a light spectrum equivalent to the ambient light at 6m depth
    - Ready for wireless Remote Control RC1
    - 9 logarithmic power levels
    - 1:80 dynamic range...

  • Filter-free Ambient Color Matching

    The revolutionary Keldan 8XR Ambient 18,000lm compact video light takes our unique ambient filter system that allows for seamless balancing of artificial and ambient light to the next level by removing the need for the filter. The 8XR Ambient’s LEDs emit light at the spectrum equivalent to the ambient light at a depth of 6m (~20’) at a luminous flux (lumen value) almost two times higher than a standard 8XR 20,000lm fitted with an external AF6B filter.

    Wireless Control Ready

    The 8XR Ambient is compatible with the powerful wireless RC1 Remote Control. The RC1 can connect to an unlimited number of lights in two groupings and allows for precise power control at distances up to 50m (~160’). Whether using the lights mounted on or off camera, the remote allows for faster and more precise control which leads to longer effective runtimes.

    Expansive Beam Coverage

    With a soft and even 110º in-water beam angle and natural looking fall-off the 8XR Ambient’s light will blend seamlessly with the existing natural light without harsh edges or uneven areas of coverage.

    Compact Intelligent Design

    The 8XR Ambient is designed with the traveling videographer in mind with a minimal footprint that adds only 0.87kg (~1.9 lbs) to your kit. In-water each light is a manageable 0.3kg (~0.66 lbs) negative which can easily be offset with buoyancy arms.

    Field Tested Tough

    Keldan lights are the choice of professionals everywhere for their reliability and extreme durability. The LED is virtually unbreakable and an almost unlimited lifespan. Thanks to a built in thermal protection circuit, the light can even be used in air without risk of damage from overheating with the light automatically adjusting output to keep the temperature in the safe range.


    Travel Ready Li-Ion Battery System

    Designed for travel and use in the most demanding filming locations the proprietary battery for the 8X system has passed the mandatory UN38.3 safety test required by IATA which means it is certified for air transport. The capacity of the battery is also below the maximum allowed 100Wh rating. Additional peace of mind is delivered by the integrated protection circuit that protects against harmful conditions such as over-discharge, deep discharge, over-current or a short circuit.

    Intelligent Information Display

    Integrated into the battery and easily viewable during use through the transparent rear cap of the light is both a visual battery level indicator with each bar representing 10% and a runtime countdown which shows the time remaining at the current power level. When connected to the charger the display shows the charge time remaining and battery charge level.
