Halcyon Focus and Flare

After 3 years of development, Halcyon is setting the standard for primary dive lights again.

LED is difficult to focus. Instead of pushing a lot of power to the LED, which is inefficient and generates a lot of heat, Halcyon invested time and resources in developing a lux engine, generating a high intensity, focused beam, while consuming half of the power of 21 watt HID lights.
With more of the light focused into a tighter location, Halcyon LED primary lights easily outperform 21 watt HID lights.
Both lights have a fully adjustable handle, which can be set to left or right hand operation. The adjustable power switch can be set to off, medium, or high power.

Halcyon applied this new lux engine in three new products:

The Halcyon Flare uses a fixed beam in a compact housing for those customers seeking high quality performance on a budget.

The Halcyon Focus offers an adjustable beam to switch between intense focus or a wide beam for underwater video purposes.

The Halcyon Flare Handheld is a fixed-beam cordless light:


The Halcyon Focus Handheld is an adjustable-beam cordless light:


  • 5 hours run-time with a 5.2 amp-hour battery pack (Focus and Flare Handheld gets 2.5 hours with a 2.6 amp-hour battery)
  • adjustable-focus beam (Halcyon Focus only)
  • fully adjustable handle
  • 39,000 lux at 1 meter (Focus at max. power)
  • weight is only 1.4 Kg
  • choice of traditional continuous cord or underwater quick disconnect (E/O) cord for the Focus and Flare


Lux ratings on max power
Distance from light 1 meter 3 meters 5 meters
Focus 39,300 4,100 1,550
Flare 11,500 1,700 650

The Focus and Flare lights produce 710 lumens. Please note that lumens are not an accurate indicator of useable light in a diving scenario. Lux ratings are an industry standard for diving lights. Click here for more information.
