LED Bulb with variable power

The LED bulb provides excellent daylight quality illumination with a color temperature of 5'000 kelvins. A unique feature is the variable power with 5 settings ranging from 2.8 - 37 Watt. The power is regulated so that you can always get maximum performance, independent of the discharge state of the battery.

Small and lightweight

The design is optimized for very small dimensions and lightweight. You cannot find another light on the market as small and powerful as the Dive 4S.

Though 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).
