Princeton Tec APX21-BK/DK Led Headlamp 550 Lumens

Product Description

The PRINCETON TEC APX21-BK/DK is an LED headlamp designed for hands-free task lighting in demanding work environments. It delivers 550 lumens of output on high mode and offers two operating light modes to match output to the task at hand. The lamp housing is constructed from Xylex plastic with a pivoting head that allows the beam to be directed without repositioning the unit. Four AA alkaline batteries are included, and the unit supports rechargeable battery use. Run time reaches up to 150 hours depending on mode. Licensed electricians, maintenance technicians, and trade professionals working in low-light conditions are the primary installers and users of this unit.

The APX21-BK/DK suits residential and light commercial applications where portable, head-mounted lighting is required. Typical use cases include equipment rooms, crawl spaces, attic work, panel inspections, and service calls where ambient lighting is absent or inadequate. The pivoting head adds flexibility for close-up inspection tasks or angled work surfaces. The included head strap allows for a secure, adjustable fit during active use.
