Aquabeam DHL-4 helmet light

The Aquabeam DHL-4 is a tough, compact and cost effective helmet light ideal for the inshore diver.

Operating with 12 volt reflector lamps with power outputs of 12, 20 or 35 watts the DHL-4 is rated to a maximum depth of 300 metres.

By using either the 'stay-put' friction bracket or the universal mount bracket, the DHL-4 will interface with most modern helmet faceplates including the Kirby Morgan range of helmets and masks.

The DHL-4 is supplied without lamp, with fixed universal mounting bracket and with either 2 or 4 pin connector.
