movement. Dirt may become trapped along the focusing barrel, creang
fricon between the test tube and light head. To clean the dirt from the
bulb assembly, simply loosen the locking screw and push the bulb assembly
out toward the cord. Clean the light head and bulb assembly. Be careful not
to pull a stuck assembly out by the cord while underwater as the tube may
come free from the assembly, ooding the light. The groove on your light
head's bulb assembly will prevent the unit from being accidentally pulled out
from the light head by an entangled cord.
LED Lighting Systems
The promise of LED technology that can fully replace HID lighng just took a
step forward with Halcyon’s Eos primary light. The new Eos capably blends
numerous desirable features with a focused light output exceeding the
10-wa HID. The Eos also reduces baery consumpon with an ecient
array of dual-intensity LEDs and a quick ip of the switch more than doubles
the baery’s run me. A machined aluminum head shields a nearly
indestrucble LED light array with an expected
lifecycle of 20,000 hours.
The Eos LED primary light has a voltage
protecon circuit to keep the baery voltage
from dropping to a level that may be harmful
to the baery pack. This circuit is acvated at
approximately 9.8 volts and will cause the light to
alternate between normal intensity and notably
reduced light output. This “icker” exists as a
warning to indicate the light is nearing its capacity. Because the reduced light
output decreases the draw on the baery, your light might connue in this
fashion for approximately 30 minutes (depending on the baery, light output,
temperature etc). The light will shut o completely as nears 9.4 volts. This
cuto will prevent damage to your baery.
The Eos LED primary light is also ed with a temperature protecon circuit
to prevent the diodes in the LED from overheang; this will help ensure
maximum LED longevity. The temperature protecon circuit will trigger a
reducon in light output similar to the low voltage cuto. In this case, the light
reduces output by 50%. It will alternate between normal and 50% output unl
the heat problem is resolved. Overheang can be most quickly resolved by
immersing the light in water. Ideally, the Eos, like all other dive lights, should
not be used at the surface for any extended period. It is unlikely that your Eos
LED should ever experience an overheang situaon while used underwater.
Halcyon has taken great strides to ensure your Eos LED will operate awlessly
without any addional adjustments. The LED module and the unique
aluminum light head work as a unit to provide the Eos with opmum heat-
syncing ability; this together with proper alignment help ensure maximum
