Open Box Dive Lights — Primary and Backup Torches

Even a bright midday reef looks different under a torch — the reds and oranges that water filters out come back, and what looked uniformly blue turns out to be covered in colour. On night dives, in wrecks, and under ledges, a light isn't an enhancement; it's the whole dive.

This collection covers primary and backup dive lights across a range of outputs and beam types. Every item is inspected and graded before listing; see Product Conditions for full definitions.

Beam Angle Determines Use

• Narrow (8–12°) — penetrates particulate rather than lighting it up, and produces a defined circle for light signalling. The technical and night diving standard.
• Wide flood (90–120°) — even coverage for video and photography, and better for general reef illumination where you want to see broadly rather than far.
• Dual beam — switches between the two, covering both roles in one light.

Burn Time Is the Number That Matters

Lumen output gets the headline, but burn time at the output you'll actually use determines whether the light lasts the dive. A torch advertised at twenty hours is quoting its lowest setting; at full output the same light may run two. Plan against the high figure, and add margin for cold water, which reduces battery performance.

Rechargeable lights need battery health checked on any used purchase. Lights taking standard cells sidestep the issue entirely — fit fresh batteries and the light is effectively new.

What to Check Before Ordering

• Charger included. Proprietary chargers are commonly separated from returned items.
• O-ring condition. Inspect and consider replacing before first use.
• Switch operation. Confirm it cycles cleanly through modes; switches are the most common mechanical failure point.
• Depth rating. Check it covers your diving.

Frequently Asked Questions

How many lights should I carry?

For night diving, at least a primary and a backup. For any overhead environment, a primary and two backups is the standard, since a light failure in a cave or wreck without redundancy is a serious situation rather than an inconvenience.

How do I check battery health on a used light?

Charge it fully and run it at maximum output, timing how long it holds before dimming. Compare against the manufacturer's stated burn time. Significant shortfall means a tired cell — often replaceable, but factor in the cost.

Why do technical divers use narrow beams?

A narrow beam cuts through suspended particles instead of illuminating them, and produces a defined spot that can be moved deliberately as a signal. Light signalling is the primary communication method in overhead environments where hand signals may not be visible.

Do open box lights come with a warranty?

No. Open box and used products are not eligible for manufacturer warranty coverage.
