The Night Eyes Green Single Beam Headlamp Kit allows you to adjust the brightness level from 10-100% and have programmable features such as strobe, flash, etc.. The HL08 series headlamp weighs only 6 oz and has a runtime of over 9 hours when brightness is set to 30%, so it can easily be worn all night long without extra strain or recharging. When set to 30% brightness this beam allows you to see an approaching coyote over 300 yards away. An optional halo shield is included to help prevent unwanted peripheral light from shining on your equipment and spooking your next kill. Night Eyes Green Single Beam Headlamp Kit HL08-G
