Flexible Metal Gooseneck Bracket

Mounted on a sturdy, flexible metal gooseneck, the SP20 allows full 3D adjustment—tilt, height, and angle—to achieve perfect coverage and make maintenance easier than ever.

Water Prooef：IP65

The SP20 is built to handle the high-moisture demands of marine systems. With an IP65+ waterproof rating, it resists splashes, humidity, and even accidental submersion. If the light falls into the tank, it won’t be damaged immediately.

💡 Pro Tip:

While the light is water-resistant, we recommend not submerging it for long periods. Prolonged underwater exposure may affect its lifespan and water quality.
