Primary Dive Lights

Primary dive lights are used for daytime or nighttime dives. They are typically brighter than 600 lumens and offer a long run time at a high-power setting. They should be durably built, giving at least a decade of service. Ideally, they can be powered by disposable and rechargeable batteries offering maximum versatility on dive trips. They are available in a grip style handle or traditional straight grip.  

SeaLife’s Sea Dragon Primary Dive lights include the compact Mini 900S, and the Mini 1300S.   The “S” indicates narrow Spot beam

The Sea Dragon Mini 900S offers impressive brightness with a focused narrow beam. The runtime is exceptional at its three power levels when used with a rechargeable 3400mAh or 3500mAh Li 18650 battery. The light is the ideal companion on both day and night dives. The Mini 900 offers SOS and 1-second flash signaling options. The narrow beam helps to point out objects of interest and to see into holes, caves, and cracks.  The Mini 1300S offers the same features with a powerful 1300 lumen beam. 

Secondary or “Back-up” Dive Lights

The main function of a back-up or secondary dive light is to aid the diver during a nighttime dive in the event the primary light fails. Backup lights are typically more compact and lightweight and can be stored in a pocket or clipped to the BC. Secondary dive lights are also ideal for pointing to or pointing out objects or creatures under rocks, reef or in the shadows. 

SeaLife’s Sea Dragon Mini 900S is the ideal backup light due to its small size. The power and run time of this light make it suitable as a primary or secondary dive light.   

Underwater Photography and Video Lights

With the development of powerful Lithium-Ion batteries and bright, energy-efficient LED light sources, lights for imaging have changed dramatically. At the same time, newer high-resolution HD still and video cameras demand light to show brilliant colors across a wide spectrum.

If you want to do underwater photography or video, a wide beam light is a necessity to illuminate your subjects and create colorful images. Compare a dull, drab image taken without light to one with and it’s truly a night and day difference. While many cameras allow you to manually adjust the aperture or shutter speed, there simply is no substitute for a bright, steady and wide beam of light.

SeaLife is a pioneer in imaging lighting by offering performance that is especially well-suited for modern digital still and video cameras. SeaLife’s Sea Dragon Photo/Video lights feature an extremely wide beam angle of 120° with brightness powerful enough to illuminate any underwater scene. But, that’s not all- SeaLife has developed lights with a high CRI or Color Rendering Index that offer a better underwater color rendition than most commonly used LED lights. The way this works is simple; natural sunlight above the water’s surface will have a color rendering of 100 – several of SeaLife’s Sea Dragon lights offer a CRI in the mid-90’s CRI range.

SeaLife’s latest light, the Sea Dragon 5000+ features a high 6000 maximum lumen output with an impressive 90 CRI, the new Sea Dragon also has SeaLife’s new patent-pending “Color Boost” which blends the high CRI white beam with its proprietary red LED’s.

An important feature in underwater LED lighting is consistency across the entire beam angle. A light with a “hot spot” in the middle and with fading brightness to the edges is simply unusable for quality underwater stills or video. SeaLife’s Sea Dragon, through the use of powerful Chip on Board or “COB” LED arrays, offer a wide and consistent beam for optimal color and brightness across the entire image, whether still photo or video.

Battery and Light Safety

SeaLife has been a long leading developer of safe underwater lights. Each SeaLife dive or underwater light features an emergency one way “gas-off” valve in case the batteries heat up or discharge gas inside the sealed underwater light. This valve prevents the body of the light from bursting. Many off-brand or low priced underwater lights do not offer this important safety feature. SeaLife uses only the highest performance certified Lithium Ion batteries; each battery is individually inspected for both safety and quality performance.
