The HPS-1000 Droplight is a high performance underwater
utility light developed for nuclear refueling tasks.
Featuring a 1,000 watt high pressure sodium lamp, the HPS-1000
Droplight provides eight times the light output and lasts an average
of ten times longer than conventional incandescent lamps.
Intrinsic to the design of the HPS-1000 Droplight is our patented
bonding process. A flexible insulating compound is used to permanently
bond the 1000 watt HPS bulb to an electropolished stainless steel
base, which provides shock absorption and eliminates the need for
gaskets or seals.
The HPS-1000 Droplight also features a protective outer quartz
envelope which surrounds the bulb's sodium arc tube, providing a
thermal barrier. This allows the light to go from air into water
while in operation without damage. The lamp is extremely rugged
with no filaments to break and for added protection an electro-polished
stainless steel screen completely encloses the entire bulb assembly.
The system includes the HPS-1000 Droplight, reflector, detachable
power cables, and a regulating ballast power supply. With a diameter
of just 3.5 inches, the droplight can be easily lowered through
small openings and recovered without snagging problems. Also, the
system is coupled to the light head by a Kellums grip attached to
the cable for secure deployment, retrieval, and provides strain
relief from the connector interface.
The HPS-1000 Droplight is available with two reflector options
that can be easily installed or removed for different applications.
The standard reflector directs the light downward. The optional
side looking reflector directs the light to the side and has a weighted
base to stand self supported in the flow holes of the lower core
support plate.
An optional cable management system includes the ballast power
supply and cable reel with slip rings mounted on a high-density
polyethylene platform.
