Sea Frogs SL-21 3500 Lumen Waterproof Video Light For Diving Photo: 3500 lumens brightness
Dive into the depths with the Sea Frogs SL-21 3500 Lumen Waterproof Video Light—your underwater photography's new best friend. Imagine capturing the ocean's mysteries with crystal-clear clarity, thanks to its blinding 3500 lumens brightness. And yes, it laughs in the face of pressure, staying waterproof down to 40 meters (that's 130 feet for us land lovers). Perfect for when you're exploring the abyss or just showing off at your local dive spot.
Now, let's talk features, because this little beast is packed. First off, it's got more modes than your favorite spy movie: fiber optic trigger for those high-tech moments, a blinding high light mode (3500 lumens, because why not?), a more subdued low light mode (1500 lumens for when you're feeling chill), SOS for emergencies (hopefully never needed), and red and blue lights (each at 3.5 watts) for setting the mood—underwater rave, anyone?
Power? It's got that covered with rechargeable 18650 lithium batteries (sold separately, because of course they are). Built like a tank with PC110 + aluminum alloy, it's ready to take on whatever the ocean throws at it. And with a 120-degree illumination angle, it lights up your underwater world like a mini sun. Plus, the LEDs promise a marathon 50,000 hours of life—that's a lot of underwater selfies.
Size? A compact 124.4 x 56 x 86mm. Weight? Just 360g (body only)—light enough to not drag you down. Whether you're a pro diver or just someone who loves to snap pics of fish, the Sea Frogs SL-21 has got your back (and your front, with all that light).
