Bigblue 2900 Lumen Narrow-Beam Tech Light (TL2900P) - Glossy Black
Cut Through the Dark. Focus on What Matters.
For serious technical divers, penetrating light is everything. The Bigblue TL2900P (2900 lm narrow-beam tech light) pairs ultra-bright output with a tight 10° beam for precision, long distance reach, and clarity in the deepest, darkest dives.
Key Features & Benefits
-
Tight 10° beam for precision
The narrow 10° beam cuts through murk and highlights distant features — excellent for penetrating caverns, overhead spaces, or deep wreck interiors. -
High output + power modes
At full power, you get 2,900 lumens (cool white, ~6500 K). But you also have 3 lower modes: 1,450 lm (level III), 725 lm (level II), and 290 lm (level I). -
Balanced burn times
Expect ~1.5 hours on full power (level IV), ~3 hours (level III), ~6 hours (level II), and ~15 hours on lowest mode (level I). -
Rechargeable 32650 Li-ion battery included
The light is self-contained with its battery and charger included. The push-button interface includes a color-coded battery level indicator so you always know how much energy remains. -
Robust, depth-rated construction
Built from a single piece of anodized aluminum, the TL2900P is depth tested to 100 meters (≈ 330 ft). -
Complete kit & accessories
The package includes: the light, charger, battery, spare O-rings, silicone lube, lanyard, Goodman glove, lantern handle, dry bag, and 12-month manufacturer’s warranty.

Ideal for:
-
Technical / deep divers who need a precise, penetrating beam for challenging environments and tight spaces.
-
Cave, wreck, and overhead expeditions where control and reach are critical.
-
Penetration inspection & mapping — highlighting walls, formations, or structural features at a distance.
-
Backup or primary light — powerful enough for primary use, yet refined enough for redundancy.
