Up to 3,000 lumens, a full color range, and single-bolt bracket mounting make it an easy way to light up the water behind your pontoon at the sandbar or the dock.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Shadow-Caster SC3-RGB-ALTB is the light we point pontoon owners to when they want real color and real brightness without a complicated install. It's a 3-inch round underwater light with a hard anodized aluminum housing, and it's designed specifically for bracket mounting on an aluminum pontoon tube. One bolt, one gasket, and you're lit up. That small footprint is the whole point. You don't need a big thru-hull or a fiberglass transom to run one of these, which makes it a realistic weekend project for most owners.\u003c\/p\u003e\n\u003cp\u003eBrightness is where the SC3 earns its keep. You get up to 3,000 lumens out of a light this size, thrown across a wide 120 degree beam. So instead of a tight spotlight, you get a broad wash of color that spreads out under and behind the boat. Anyone who's anchored at the sandbar after dark knows the difference that makes. Fish show up. The water glows. And with full RGB color, you can dial it to whatever mood the night calls for, from a clean daylight white to deep blues and greens. Change it to match the game, the holiday, or just how the evening feels.\u003c\/p\u003e\n\u003cp\u003eBuild quality is the reason Shadow-Caster has the reputation it does. The lens is tempered glass, scratch resistant, and the anodized aluminum housing shrugs off acetone, solvents, and the general abuse of a boat that lives on a trailer or a lift. Inside, the whole unit is filled with a proprietary clear gel that's injected through the entire body. That gel is what keeps condensation and water intrusion out even when the light is working hard and heating up. It's a made-in-America design, and it feels like it in your hand.\u003c\/p\u003e\n\u003cp\u003eThere's some smart protection baked in too. The SC3 has transient surge and reverse polarity protection, so a wiring mistake or a dirty power spike won't instantly cook it. It also has integrated thermal protection, which matters more than people expect. Underwater lights are cooled by the water around them. If you flip these on while the boat's on the lift or the trailer and the light's out of the water, the thermal protection keeps it safe until it's back under and submerged again.\u003c\/p\u003e\n\u003cp\u003eLet's talk install, because this is where the SC3-ALTB is honest about what it's for. It's a freshwater light, built for trailer-kept and lift-kept pontoon boats. This is not the one to leave sitting in saltwater year round. Mount it on the pontoon bracket, run the included 3-foot cable up to your switch, and fuse it appropriately. It draws about 1.5 amps of continuous current on 12 volts, so it's an easy load on almost any pontoon's electrical system. One tip from the field: if you're running a long wire from the helm back to the light, use a heavy enough gauge to avoid voltage drop. Skinny wire on a long run will dim the LEDs and dull the color. And seal the cable entry properly so you don't get water creeping in over a season.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Pontoon owners who spend evenings on the water and want their boat to stand out at the raft-up. It's a clean single-light solution for a smaller pontoon, and it scales beautifully if you want a pair or a set for a bigger deck boat. The IP68 rating means it's fully submersible and sealed, so once it's mounted and wired, you can pretty much forget about it and just enjoy the show. For the money, it's one of the easiest and most satisfying upgrades you can make to how your pontoon looks and fishes after sunset.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eUp to 3,000 lumens from a compact 3-inch housing for a bright, wide wash of underwater light\u003c\/li\u003e\n  \u003cli\u003eFull RGB color range so you can set white, blue, green, or any mood color\u003c\/li\u003e\n  \u003cli\u003e120 degree beam angle spreads light broadly under and behind the boat instead of a narrow spot\u003c\/li\u003e\n  \u003cli\u003eHard anodized aluminum housing with scratch-resistant tempered glass lens stands up to solvents and marine abuse\u003c\/li\u003e\n  \u003cli\u003eProprietary gel-filled body injected through the entire unit to block condensation and water intrusion\u003c\/li\u003e\n  \u003cli\u003eTransient surge and reverse polarity protection guards against wiring mistakes and power spikes\u003c\/li\u003e\n  \u003cli\u003eIntegrated thermal protection allows safe operation briefly out of the water\u003c\/li\u003e\n  \u003cli\u003eIP68 fully submersible waterproof rating for permanent underwater mounting\u003c\/li\u003e\n  \u003cli\u003eSingle-bolt bracket mount sized for aluminum pontoon tubes, no large thru-hull needed\u003c\/li\u003e\n  \u003cli\u003eLow 1.5 amp continuous draw on 12 volts, easy on any pontoon electrical system\u003c\/li\u003e\n  \u003cli\u003eMade in America design\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Shadow Caster reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eCan I use the SC3-RGB-ALTB in saltwater?\u003c\/summary\u003e\n    \u003cp\u003eNo. This model is designed for freshwater use on trailer-kept and lift-kept boats.
