The Bigblue VTL4200P and AL1300NP combo pack pairs a high-output primary LED dive light with a compact backup scuba diving flashlight for versatile underwater illumination. The VTL4200P delivers up to 4200 lumens on its highest setting with selectable wide (120°) and narrow (10°) beam angles, while the AL1300NP supplies a focused 1300-lumen narrow beam for penetration and signaling. Both lights use XML LEDs and rechargeable Li-Ion BATCELL batteries (32650 and 18650 compatible), feature anodized aluminum alloy housings, and are rated to 100 meters (328 ft) depth for diving and technical use. The kit includes spare O-rings, removable yellow and red filters, two chargers, lanyards, silicone lubricant, and a one year limited warranty.

Adjustable power levels on the primary light provide multiple burn-time profiles—up to approximately 2 hours at maximum output and progressively longer runtimes on lower settings—making it suitable for extended dives and search tasks. The compact backup light offers simple controls and quick deployment for close-quarters or secondary illumination. The set supports field maintenance with spare parts and included silicone lube to preserve seals and long-term waterproofing.
