SF100B Underwater FishLight

Fire up a fish-feeding frenzy with the original SF100B Underwater FishLight. This powerful light features our IntesiTech Right Bright LEDs that deliver unmatched intensity—the exact light frequency fish recognize and respond to.The IntensiTech LEDs used in a HydroGlow Underwater Light are unmatched for brightness. Just one of our LEDs could be used to power a flashlight. We use 100! And, we’ve increased the brightness by 90% over the last three years. 

The SF100B is designed to anchor to the bottom, projecting upward. Protected by our shatter-resistant HydroDome and Elude eco-friendly barnacle-resistant coating. We coat all SF model HydroGlow Underwater Lights with Elude, a revolutionary eco-friendly (biocide-free) marine coating that has effectively tripled the barnacle-free operational time of our lights. 

The critical components and LEDs are flooded with Impervia, a state-of-the-art
marine epoxy resin, to construct our lights. Other resins retain some level of porosity
which can allow micro-droplets of brine to penetrate, potentially resulting in corrosion
or light failure. It also has a higher flexural strength rating. And, unlike polyester,
Impervia is very resilient and less prone to shrinkage or warping, meaning it can
withstand an extreme range of water temps from a summer ocean to under the ice in
the winter.

Each light includes a 50' cord (extra lengths available) and is perfect for creating a "See The Light" Safe Zone that attracts fish to your dock, waterfront dining area, or favorite fishing spot. The SF100B also helps "Bring 'Em Up" from deeper waters during warm summer months when fishing is typically more challenging.

Made in America. Built right. Backed by our "Proven Attraction" Performance Guarantee.

Technical Specs:

SF model lights should not be turned on in the air for longer than 2 minutes. 200 high-power LEDs are used to better illuminate an area from underwater in a 120deg field. For a wider spread of light place the light deeper in the water. The SF series uses a 48V driver which is IP67 rated with a 6’ cord on the input side and needs to be plugged into 120VAC. This driver can be left outside in the rain without worry. 

• Voltage: 48VDC (With 100W 120VAC driver)

• 31 lumen/LED with 96LEDs = 2950 total lumen output in one direction
• Length 9” total length including 4” cord grip
• Diameter 4”
• Wavelength 475nm Blue
• Weight: 4.2 lbs

50 foot cord included with an IP68 waterproof locking connector to the driver. Driver has 1’ of length on output side and 6’ length on input side

Q: "Should I choose Blue or Green?"

A: Water naturally filters light. The colors least scattered under water are in the green/blue part of the spectrum. This is why water appears either green or blue. At night, introducing green or blue light stimulates the micro flora that tiny bait fish eat, which in turn, attracts small fish that see the glint and flicker of the tiny feeding fish (and at maximum distances since green/blue light travels the furthest in water) which in turn creates a feeding frenzy that attracts the predator fish. So which is the right color?  While green can be used in both freshwater or saltwater, we suggest blue for saltwater since it will travel further and reach the most fish.
