Aquabeam HB-21 Hyperbaric Light


The Aquabeam HB-21 is a hyperbaric light fixture designed to provide general illumination within the diving bell (SDC) or decompression chamber (DDC).

The HB-21 embodies a rugged 24 volt, 21 watt incandescent bulb which is available with either a clear or frosted envelope.

The lamphead is fitted with a helium relief valve to eliminate post decompression explosion hazard, and a stainless steel cage protects the glass dome from accidental damage.


  • Heat sink plate available to provide additional cooling
  • Integral On / Off switch offers individual control of the light

The Aquabeam HB-21 Hyperbaric Light is pressure tested to 70 Bars, DNV type approved and ideal for chamber bunk lighting.
