Description

The EOS23 Canister Sidemount is the power half of Bigblue’s EO canister system. It does not include a light head. Pair it with the TL4000P EO light head for a narrow-beam primary, or the VTL8000P Max EO light head for a dual-beam light; both are sold separately. Bigblue lists it as a Tech primary power source.

Inside are three BATCELLEOCANISTER Li-ion batteries of 88.06 Wh each, in a configuration Bigblue lists as airline approved. With the TL4000P EO head that means 12 hours at 4000 lumens and up to 120 hours at 400 lumens. With the VTL8000P Max EO head, the flood beam runs 8 to 32 hours.

The EOS23 has one cable and a mechanical on/off switch. Bigblue designed it to power more than a light: it can also supply heated gloves, vests and full heated undergarments from the Powered Heat Sync series. To run a light and heated gear at the same time, the EOD23 has two independent cables.

This is the sidemount version, set up for divers on a sidemount rig. The canister is 68 x 290 mm, weighs 2300 g with batteries and has a 0.65 m cable. The backmount version has the same specs. It is anodized aluminum alloy, tested to 150 meters.

A charger and a 15L outdoor dry bag are in the box. This listing is Classic Black; Bigblue also makes it in Royal Blue and Hot Pink.

Frequently Asked Questions?

Does this include a light head?

No. The box has the canister, its battery pack, a charger and a 15L outdoor dry bag. Add the TL4000P EO or VTL8000P Max EO light head, or buy the complete TL4000P EOS23 system.

How long will it run?

It depends on the head. With the TL4000P EO head: 12 hours at 4000 lumens, 24 at 2000, 48 at 1000 and 120 at 400. With the VTL8000P Max EO head: 8, 16 or 32 hours on the flood beam.

Can I fly with it?

Bigblue lists the battery configuration as airline approved: three BATCELLEOCANISTER batteries of 88.06 Wh each. Check your airline’s rules before you travel.

How long does it take to charge?

Bigblue suggests 5–6 hours for the BATCELLEOCANISTER batteries.

EOS or EOD?

EOS canisters have one cable. The EOD23 has two independent cables, so it can run a light and a heated vest, or two lights, at the same time.
