With two spot beam brightness levels and white, red, and green flood beams, the NSP-4610C Multi-Function LED Headlamp from Nightstick covers a wide range of hands-free lighting needs. The focused 110- and 210-lumen spot beam illuminates at a distance while the flood beams provide generous close-range lighting. The red and green colors can help preserve night-adjusted vision. A non-slip elastic head strap keeps the light snugly and comfortably in place, and the ratchet-tilting head allows the beam to be placed right where it's needed. The camouflage elastic headband and flat dark earth coloring make the NSP-4610C suitable for use when hunting or shooting wildlife photography. The NSP-4610C is waterproof and tested to withstand being dropped from 6.6'. The runtime on a fresh set of three AAA batteries is 4.5 to 8.5 hours on spot and 4.5 to 25 hours on flood beam.
