Professional lighting. Compact enough to travel anywhere.
A professional video light that gives you maximum lighting performance with minimum equipment weight.
The remote controllable KELDAN Video 4XR packs 11,000 lumens of high-quality 5600 K light into an exceptionally compact and travel-friendly housing. Designed for underwater filmmakers who want serious illumination without carrying unnecessary weight, it delivers a smooth, speckle-free 110° beam underwater with natural-looking color and soft, even coverage.
With nine logarithmic power levels and a 1:50 dynamic range, the 4XR gives you precise control from subtle fill light to full output. Its integrated 49 Wh Li-Ion battery, USB-C charging adapter and self-contained design make it an ideal companion for travel, compact camera systems and demanding dives.
USB-C charging adapter
Attention: The light is supplied with a USB-C charging adapter only but not with the USB-C charger (min. 30W).
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.
Tough Design
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 CE, FCC and 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, at the end of each battery, 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).
