Bigblue 1300 Lumen Narrow Beam Dive Light

Bigblue 1300 Lumens Narrow Beam Dive Light: A Focused, Rechargeable Primary Light for Serious Divers

The Bigblue 1300 Lumens Narrow Beam Dive Light is a handheld primary dive light built around one specific strength: a tight, powerful beam that cuts deep into dark water.

If you are a recreational or technical diver who regularly dives wrecks, caves, or low-visibility sites, and you want a light that punches through murk rather than spreading wide, this is worth your attention.

If you are looking for a wide flood light to illuminate a reef broadly, this is not that light. The 10-degree beam angle is narrow by design, and that distinction matters before you buy.

What the Beam Actually Does for You

A 10-degree beam is a pencil of light, not a lantern. At depth, that focus lets you direct 1300 lumens onto a single point: into a crevice, along a hull plate, or toward a subject you are trying to identify.

In silty or low-visibility water, a wide flood can backscatter, bouncing light off suspended particles straight back at you. A narrow beam like this one travels further through the water column before it disperses, which is why this geometry suits wreck penetration and dark-water searches better than open-water reef cruising.

The light source is an XML LED running at 6500K color temperature, which sits in the cool white range. That tone renders blues and greens crisply and works well for navigation and signaling, though it is not optimized for photography or video color accuracy the way a warmer or tuned white light would be.

Output Levels and Burn Times

Four brightness settings give you real flexibility over the course of a dive day.

Two hours at full power is enough for a single recreational dive, but plan carefully if you are doing multiple dives in a day at maximum output. Dropping to Level III doubles your runtime without a dramatic loss of usable brightness, which is a practical choice for most wreck dives where you do not need every lumen the whole time.

The color-coded battery indicator takes the guesswork out of monitoring charge during a dive. There is also an SOS flashing mode, useful if you surface in poor conditions and need to signal a boat or support diver.

Build and Depth Rating

The body is machined from anodized aluminum alloy, which handles pressure and impact better than plastic housings and resists corrosion in saltwater with basic rinse care.

Bigblue rates the light waterproof to 150 meters (492 feet) tested depth, which exceeds the range of recreational diving and comfortably covers technical diving profiles. The depth rating gives you meaningful headroom rather than a figure you will ever approach on a normal dive.

Weight with battery is 168 grams (5.9 oz), and buoyancy is slightly negative at -76 grams. That small negative buoyancy means the light will not float away if you let go, but it is light enough that it will not fatigue your hand during a long penetration dive.

Power and Charging

The Bigblue 1300 runs on a single rechargeable 18650 lithium-ion battery, which is included along with a charger. The 18650 is a standard cell format, so replacements are widely available if you want a spare for back-to-back dives without waiting for a recharge.

Carrying a second charged 18650 is a practical habit for dive trips where shore power is limited or access to charging is inconvenient.

What Comes in the Box

• Bigblue 1300 Lumens Narrow Beam Dive Light
• Rechargeable 18650 lithium-ion battery
• Battery charger
• Wrist lanyard
• Roll-top dry bag
• User manual

The roll-top dry bag is a practical inclusion for travel, keeping the light and its accessories protected in a wet gear bag or during surface transport.

Interchangeable Light Heads

One of the more useful aspects of the Bigblue 1300 is that the light head is not fixed. Bigblue makes several compatible heads sold separately, which means this body can be adapted for different jobs without buying an entirely new light.

• LH-AL1300STROBE: strobe head for signaling
• LH-AL1300WP: wide-angle flood head
• LH-AL1300XWP: extra-wide flood head
• LH-AL1200RAFO: alternative beam configuration
• LH-RGBWhite: RGB color head

If you eventually want a wider flood for reef dives or a color head for photography, you can swap the head rather than replace the entire light. That modularity extends the usefulness of the body significantly over time.

Who This Light Is For, and Who It Is Not

The Bigblue 1300 suits a diver who dives in conditions where a focused beam is an advantage: wreck penetration, cave entrances, dark-water night dives, and low-visibility searches. The narrow angle, solid depth rating, and manageable size make it a capable primary light for recreational divers pushing into more challenging environments, as well as a useful tool for technical divers who want a compact backup or secondary torch.

It is not the right choice if your primary need is wide scene illumination for reef photography or video. For that, one of the wide-head options would serve you better, either as a separate purchase or by pairing this body with the WP or XWP head sold separately.

If you dive in low visibility regularly and have been relying on a broad flood, the difference a tight 10-degree beam makes in those conditions is worth experiencing firsthand.
