Product Information

The Seac SZ5000 is a rechargeable underwater flashlight built for scuba divers who need strong, adjustable output in a compact body, putting out 1500 to 4200 Lumens from an internal 7800 mAh lithium-ion battery through a focused 12° beam.

Who it is for

The SZ5000 suits divers who want serious light for reef night dives, caves or wrecks, or underwater photography where color and detail matter in low light. Its compact 65 mm by 178 mm body fits in a BCD pocket or attaches with the included wrist lace, so it stays within reach without adding bulk to standard scuba gear.

Key details

Three CREE SST 40 LEDs push out up to 4200 Lumens at full power through a 12° beam angle, with output adjustable down to 1500 Lumens to extend run time. Burn time runs from about 1 hour at maximum power to roughly 2.5 hours at minimum power. The internal 7800 mAh lithium-ion battery recharges through USB-C and has a built-in charge indicator. A flashing mode doubles as a visual alarm, and an electromagnetic switch with a safety lock prevents the light from turning on by accident. The body is high-strength aluminum with a tempered optical glass lens and a watertight NBR O-ring gasket.

Frequently Asked Questions

How long does the Seac SZ5000 run on a single charge?

On its internal 7800 mAh lithium-ion battery, the SZ5000 runs about 1 hour at maximum output of 4200 Lumens and up to 2.5 hours at its minimum setting of 1500 Lumens. Adjusting brightness balances intensity against dive time, and the battery recharges through the light's USB-C port.

What comes with the Seac SZ5000?

Each SZ5000 ships with the torch itself, a wrist lace for securing it during the dive, and a semi-rigid protective case for storage and transport. The wrist lace keeps the light attached to the diver's hand so it stays accessible without needing to be held constantly.

Does the Seac SZ5000 have a signal or alarm feature?

Yes, the SZ5000 includes a flashing light function that can be used as a visual alarm to signal other divers underwater. It also has an electromagnetic switch with a built-in safety lock, preventing the light from turning on accidentally while stored or in transit.

How bright is the Seac SZ5000 compared to other dive lights?

The SZ5000 outputs up to 4200 Lumens at full power, adjustable down to 1500 Lumens, through a focused 12 degree beam powered by 3 CREE SST 40 LEDs. That combination of high lumen output and a 12 degree beam suits cave, wreck, and reef night diving where full visibility matters.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.

New to this hanger...Now I'm a believer

Used tons of dive hangers, but never an upside down hanger. Game-changer for me. Will now add more of these in the near-future.

With it's swivel head design, it can cram itself into my tight dive locker, while still donning a ton of gear.

DiveCatalog's "Upside Down Drysuit Hanger w/ Regulator and Accessory Hooks" is a great product with solid construction at an affordable price. All of that with Dive Catalog's customer support/satisfaction guarantee.
