Big Blue TL3800P and AL1300NP Technical Diving Combo Pack Narrow-Beam

The Technical Diving Combo Pack pairs the TL3800P primary light with the AL1300NP backup to provide focused underwater illumination for technical dive applications. Both dive lights use XML LEDs and deliver a narrow 10° beam option for penetration and precise spotting; the TL3800P is rated to 3800 lumens while the AL1300NP is rated to 1300 lumens. Rechargeable Li‑Ion batteries (BATCELL32650 and BATCELL18650) power the lights with suggested charge times of about 6–7 hours and 3–4 hours respectively, and multiple output levels yield run times from roughly 2 hours at the highest output to up to 20 hours on low settings.

Anodized aluminum alloy housings provide corrosion resistance and impact durability, and push‑button controls are designed for gloved use. The kit is tested to 328 ft (100 m) depth and includes spare O‑rings, removable yellow and red filters, lanyards, chargers, and a one‑year limited warranty. This combo supports technical dive configurations needing a narrow‑beam primary and a compact backup for cave, wreck, and low‑visibility scuba diving, and is compatible with standard 18650 and 32650 chargers and common mounting accessories.
