SEAC Flash Light underwater torch for night dives up to 100 m
Reviews
Product description
What it is and why you’d want it
The SEAC Flash Light is a scuba diving torch designed for night use and low-visibility conditions. On paper, it’s aimed at situations where you need a reliable light underwater without faffing around with switches. The standout idea is that it turns on when it comes into contact with water, which can make it feel more “set and forget” once you’re already kitted up.
It’s also built around longer burn time: the base description quotes a duration of 700 hours. That’s the sort of figure that matters when you’re doing extended sessions or simply don’t want to worry every time you get ready.
Key takeaways for night and low-visibility diving
Where this torch seems to make the most sense is during night dives, or anywhere you’re likely to be dealing with dim conditions. A maximum depth of 100 m suggests it’s intended for serious underwater use rather than casual snorkelling.
One small catch to keep in mind: it’s described as a “night” torch, so if you mainly dive in bright daylight or you only need a quick surface light, you may not get much day-to-day value from a dedicated underwater option.
The essentials: how it behaves in use
The most practical feature here is the water-contact ignition. Instead of manually switching it on before you enter, the torch is designed to light up when it gets wet. In real terms, that can reduce the momentary hassle of toggling something on and off while you’re already managing gloves, fins, and your kit.
For example, during a night dive briefing you might prep everything, clip the torch where it’s easy to grab, and once you’re in the water it can activate as it takes on water. That’s the kind of workflow that tends to suit divers who want fewer steps during the transition.

What stands out, and what may not
What stands out most is the combination of night/low visibility focus, a long stated duration (700 hours), and a maximum depth rating of 100 m. If you’re buying specifically for dark water and want something that’s designed to work underwater rather than “hoping it does”, this ticks the boxes.
That said, without more detail in the info provided, it’s hard to judge things like beam pattern, brightness output, or how it performs for close-up tasks versus spotting across distance. If your priority is pinpoint illumination for navigation or fine inspection work, you may want to double-check the torch’s light characteristics before committing.
Who it’s for (and who should skip it)
It makes sense if you’re regularly doing night dives or dive in conditions where visibility drops, and you want a dedicated underwater torch with water-contact activation.
It may not suit you if you’re mainly a daylight diver, or if you prefer to have precise control over when the light turns on (for example, you might want full manual control regardless of whether it’s in contact with water). You may also want to reconsider if you need detailed guidance on beam performance, since that information isn’t included here.

Final verdict
Is it worth it?
Worth considering if you want a purpose-built night/low-visibility underwater torch with water-contact activation and a 100 m depth rating, especially given the stated 700-hour duration. It’s the sort of purchase that can feel practical for divers who want fewer steps during entry and a light that’s meant to stay usable across long stretches.
Better avoided if you only dive in good daylight or you need more detailed lighting performance information (like beam output and style) to match your exact use case. If your decision hinges on brightness and beam behaviour, you’ll want to look for those specifics before buying.
