HEL-STAR 6® is a multi-function helmet mounted LED light designed for airborne/MFF, tactical and other military operations.
 
This specific Model is the one that we prefer: HS-640-18. The HS-640-18 fits the requirements and needs of most, if not all, night vision users weather it be an armed professional or a concerned civilian.
In the visible spectrum, Mode 1's function provides a low and steady green visible light and Mode 2's function provides the same visible green LEDs, but in conjunction with an FAA compliant White Strobe.
When switched into the Infrared (IR) Spectrum, Mode 1 has a low and steady set of IR LEDs and Mode 2 provides the same low stead IR LEDs + an FAA Compliant IR strobe. 
The newly refined HEL-STAR 6® Gen III offers a sleek design, integrated tie downs, battery changes without tools, and advanced electronics, including a field reprogramming option.
Sliding switches enhance tactile feel and provide positive, intuitive control between the two operating modes and four user-defined functions. Functions can be selected from virtually any combination of White, four different color options, and IR – either flashing or steady. Variable flash rates, intensities and coded signals provide expanded IFF capability.
Independent testing has confirmed that the HEL-STAR 6® Gen III exceeds the FAA’s 3 statute mile visibility requirement and is shock and vibration resistant, dustproof, and open sea waterproof to 130 fsw (laboratory 300+ feet).
HEL-STAR 6® is built on a platform that allows new technology to be incorporated as it becomes available. As mission demands shift and expand, HEL-STAR 6® continues to evolve with changing user needs.
