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.

Overtemperature Protection

Thanks to its over-temperature protection, the light can also be used outside water. The power is automatically reduced if the temperature of the housing increases due to operation outside water.

Li-Ion Battery

The Dive 4S uses a rechargeable Li-Ion battery pack 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.

Charge Display

A very precise eight segment charge level indicator on the back side of the battery gives you the charge level while charging or diving.

Safety

The deep discharge protection warns you with a flickering light about the end of burning time. When fully discharged, the light switches automatically to the LED safety light on the back side of the batterypack.
