Product Information
The SeaLife Sea Dragon Mini 900S Power Kit is a complete, ready-to-dive compact light bundle: the Sea Dragon Mini 900 LED dive light rated to 330 ft / 100 m, a 2600 mAh rechargeable 18650 Li-Ion battery and an 18650 USB battery charger. The light puts out 900 lumens from a CREE XM-L2 T6 LED in a narrow 14 degree beam on land that measures 10.5 degrees underwater.
Who it is for
This kit suits divers who want one small, pocketable light that can serve as a primary light on a night or wreck dive, a backup light, or a spotting and signaling light. The narrow beam is useful for peering into cracks and crevices and for getting a buddy's attention, and the 1-second blinking and emergency SOS modes make it a sensible safety light to clip to a BCD. Because the kit includes the battery and charger, it is also a good choice for anyone replacing a bulb-era light or buying a first rechargeable dive light.

Frequently Asked Questions
How long does the Sea Dragon Mini 900S run on one charge?
With the included 2600 mAh 18650 Li-Ion battery, the Mini 900 runs about 1.6 hours at full 900 lumen power, 3.2 hours at half power and 6.4 hours at quarter power. The colored battery indicator shows remaining power, so you can drop to a lower setting mid-dive to extend run time on longer dives.
Can I use CR123 batteries instead of the rechargeable 18650?
Yes. The Sea Dragon Mini 900 runs on either one rechargeable 18650 Li-Ion battery, which is included in this Power Kit along with the SL9825 USB charger, or two CR123 single-use batteries. The CR123 option is handy for travel or as a backup when charging is not available.
How do you switch the light modes?
The Mini 900 uses a single button. Press and hold for about 1 second to turn the light on or off, then tap the button with short pushes to cycle through the five modes: full power, half power, quarter power, a 1-second blinking signal and an emergency SOS signal.
Can the Mini 900 be mounted on a camera tray or arm?
Yes, with the optional SL98104 YS Mount accessory. That mount adapts the light to any YS Adapter or YS mounting system, so it can be attached to trays and arms alongside a camera. As supplied, the kit includes a lanyard with a BCD clip for handheld or clip-on use.
