Description

Extended runtime for extended dives

The BigBlue TL3800P-Supreme-PRO is built for divers who need more than just brightness.

Delivering up to 3800 lumens through a focused 10° narrow beam, the Supreme PRO combines strong technical-dive illumination with dramatically extended battery life.

BigBlue rates the light for approximately 5 hours at full power, making it especially well suited for longer wreck dives, cave diving, technical profiles, repetitive diving, and other situations where dependable runtime matters.

For divers who want a self-contained technical light without immediately moving to a remote canister system, the Supreme PRO offers a compelling combination of power, simplicity, and endurance.

3800 lumens of focused output

The TL3800P-Supreme-PRO produces up to 3800 lumens from three XML LEDs.

Its concentrated 10° beam is designed to project light through dark water rather than spreading illumination broadly across the surrounding area.

That focused beam is useful for:

• Wreck exploration
• Cave and overhead diving
• Low-visibility environments
• Night diving
• Team signaling
• Navigation
• Inspecting distant objects or structures

Four selectable power levels

Not every part of a dive requires maximum output.

The Supreme PRO provides four brightness settings:

• 380 lumens
• 950 lumens
• 1900 lumens
• 3800 lumens

This allows divers to reduce power when appropriate and significantly extend battery life.

Exceptional battery endurance

The defining feature of the Supreme PRO is its extended runtime.

BigBlue rates approximate burn times at:

• 3800 lumens: 5 hours
• 1900 lumens: 10 hours
• 950 lumens: 20 hours
• 380 lumens: 50 hours

That level of endurance gives technical divers substantial flexibility for long dives, repetitive diving, travel, or situations where frequent recharging may be inconvenient.

High-capacity rechargeable battery pack

The Supreme PRO uses BigBlue’s BATCELL21700x4SUPREME lithium-ion rechargeable battery pack.

BigBlue currently recommends approximately 11–12 hours of charging time for this battery on the product page.

The large-capacity pack is what allows the Supreme PRO to maintain 3800-lumen output for significantly longer than the standard TL3800P and TL3800P-Supreme versions.

Focused 10° technical beam

The 10° beam angle is designed for technical diving applications where penetration and communication are priorities.

A narrow beam helps:

• Cut through dark or low-visibility water
• Reduce unnecessary light scatter
• Highlight specific objects or areas
• Provide clear team signaling
• Maintain visual reference in overhead environments

It is a purpose-built technical beam rather than a broad video-style flood light.

Integrated battery-level indicator

A push-button switch incorporates a color-coded battery indicator.

This lets divers monitor approximate remaining battery capacity before and during the dive, reducing guesswork about available runtime.

Rugged anodized-aluminum construction

The Supreme PRO is machined from anodized aluminum alloy for strength, corrosion resistance, and durability.

Its streamlined one-piece design keeps the system self-contained while maintaining the robust construction expected from a technical primary light.

Built for depth

BigBlue currently lists the TL3800P-Supreme-PRO as tested to 150 meters / 492 feet.

That rating places it firmly in the technical-light category and provides ample depth capability for demanding recreational, wreck, cave, and technical diving applications.

Goodman glove and lantern handle included

The Supreme PRO package includes both a soft Goodman glove and a lantern handle.

The Goodman glove allows the light to ride over the back of the hand while keeping the diver’s fingers free to operate equipment.

This is particularly useful when:

• Running reels
• Managing stage or deco bottles
• Operating a DPV
• Adjusting valves
• Deploying an SMB
• Handling line in overhead environments

The lantern handle gives divers a traditional handheld option when preferred.

Compact self-contained design

Despite its large battery capacity, the Supreme PRO remains a self-contained technical light.

At approximately 63 mm in diameter and 131.7 mm long, it delivers serious runtime without requiring an external battery canister and cord.

That can be attractive for divers who want extended burn time while keeping their configuration relatively simple.

A serious primary light

The TL3800P-Supreme-PRO is well suited for:

• Technical diving
• Cave diving
• Wreck diving
• Night diving
• Low-visibility diving
• Deep diving
• Long-duration dives
• Repetitive dive days
• Dive-team signaling

For divers who prioritize runtime as much as brightness, the Supreme PRO sits near the top of BigBlue’s self-contained technical-light lineup.
