18 watt HID Light Head
Halcyon's workhorse light, the 18 watt HID, allows full adjustability
and easy bulb changes in a conventional test tube style design. Light
output is similar to a 75 watt halogen light at a fraction of the power
consumption. Halcyon 18W HID lights include our exclusive ultra-bright
reflector. We’ve designed the parabola of the reflector specifically for
diving applications, where a sharp spot is beneficial for signaling. The
surface is spun and polished to our specifications and will not chip
or flake like can happen with metal film vacuum-coated reflectors.
Combined with the extended protective cowling on our light head, the
Helios 18W lights throw out an intensely focused beam of bright, white
light that you can rely on in the most challenging of situations.
10 watt HID Light Heads
Where innovation meets practicality: Halcyon's fully-closed focusable
light head (patent pending) can be adjusted from a laser-like beam
to a diffuse soft light with the mere twist of a dial. The light head is
fully focusable by turning the
integrated knob on the back of the
light head. This unique and simple
design allows for quick focusing
and eliminates the need for an
external lock-down screw. The
entire range of focus requires less
than 1.5 revolutions.
Halcyon’s fixed-beam 10w option
provides the power of a 10w light
in a very rugged and compact
package. The fixed-beam light is
designed around an MR-11 HID
bulb that burns bright and white
with a six-degree spot.
Halogen Light Head
Conventional halogen systems utilize a filament similar to that found in
conventional light bulbs. Halogen lights have a color temperature that
is considerably lower than HID (shifting the visually perceived color
toward yellow-orange); halogen lights also have less penetration in the
water column and a much shorter burn time than a HID lamp with the
same battery pack. To their benefit, halogen bulbs are less expensive and
easily replaced with bulbs available at traditional lighting supply stores.
