12V 5050 waterproof LED strips combine the high-brightness output of the 5050 three-die chip with an IP65-rated clear silicone coating that protects against moisture, splashes, humidity, and light rain. Every LED strip in this category is engineered for environments where a standard non-waterproof strip would fail: outdoor landscape and architectural lighting, patios and decks, bathrooms, kitchen splash zones, boats and marine vessels, RV exteriors, commercial signage in exposed locations, and any installation where the strip is subject to weather or washdown. The waterproof coating seals the 5050 chips and copper traces without reducing brightness, changing color temperature, or limiting flexibility.

The core specifications match our standard 5050 strip: 30 LEDs per meter (150 per 5-meter reel), approximately 7.2W per meter power draw, and roughly 360–540 lumens per meter of output. The 5050 chip’s three-die architecture produces 2–3 times the brightness of a 3528 chip, making these the brightest waterproof strips we carry. Available in warm white, cool white, and single-color options for functional and decorative installations. RGB waterproof 5050 strips are also available for color-changing effects in outdoor entertainment areas, poolside lounges, bar patios, and event venues.

Outdoor landscape lighting is one of the most popular applications for waterproof 5050 strips. Mount along garden borders, retaining walls, fence lines, deck railing undersides, pergola beams, and tree trunks for dramatic nighttime accent lighting. The 5050 chip’s high brightness ensures the light remains visible even in ambient dusk conditions, where a softer 3528 strip might wash out. Architectural applications include facade uplighting, column wrapping, roofline outlining, and under-eave accents. For commercial installations, waterproof 5050 strips backlight outdoor channel-letter signage, illuminate menu boards on restaurant patios, and accent exterior display windows that are exposed to rain and humidity.

Marine and automotive applications take full advantage of the 12V operating voltage. Boats and marine vessels run on 12V battery systems, so waterproof 5050 strips connect directly to the vessel’s electrical system without an inverter or voltage converter. Mount under gunwales, along cockpit coamings, inside cabins, beneath dock pilings, and along dock walkways. For RVs, campers, and van builds, mount waterproof strips along the awning channel, under slide-out edges, along exterior storage compartments, and inside trunk or garage areas where condensation and humidity are common. The adhesive backing holds securely on clean aluminum and fiberglass surfaces typical of marine and RV construction.

All waterproof 5050 strips run on 12V DC and can be cut to length at marked cut lines every 3 LEDs (every 10cm). Cutting breaks the silicone seal at the cut point; reseal the exposed end with clear silicone sealant or waterproof end caps if the strip will be directly exposed to water. For connections between segments or at corners, use waterproof-rated 4-pin connectors (RGB) or 2-pin connectors (single-color), and seal the connection with waterproof heat-shrink tubing. For permanent outdoor installations, solder the connections and pot them in clear silicone for a fully weatherproof joint.

Power supply sizing is the same as for standard 5050 strips: 7.2W per meter times total length, plus 15–20% headroom. A full 5-meter reel draws 36W; use a 45W or 50W 12V power supply. For outdoor installations, the power supply must be housed in a weatherproof junction box or be rated for outdoor use (IP65 or higher enclosure). Route the 12V output wires through weatherproof cable glands, and ensure the 120V AC feed circuit is GFCI-protected. For long outdoor runs, inject power from both ends of the strip for even brightness, and use 16–18 AWG wire for the supply leads. Never exceed 5 meters in a single daisy-chain run from one feed point.

For dry indoor installations where waterproofing is unnecessary, save cost with the standard non-waterproof 5050 strip, which is thinner and slightly more flexible. For lower-brightness ambient accent lighting where the 5050’s output is more than you need, the waterproof 3528 strip provides a softer glow at lower power consumption. For short runs, browse our LED strips by the section category to purchase pre-cut lengths. Browse our wire, switches, and connectors category for strip connectors, DC barrel jacks, extension cables, and inline switches to complete your installation.

Frequently Asked Questions

IP65-rated strips are splash-proof and protected against water from any direction, but they are not designed for continuous submersion. For pools, fountains, fish tanks, and underwater features, you need strips rated IP67 (silicone tube encapsulation) or IP68 (full potting), which are sealed against sustained water pressure. IP65 waterproof strips are ideal for locations exposed to rain, splashes, humidity, and washdown, but not for permanent underwater installation.
After cutting or connecting, reseal the exposed pads and connections. For quick jobs, apply a bead of clear silicone sealant over the joint and let it cure for 24 hours. For more robust sealing, use adhesive-lined waterproof heat-shrink tubing over the entire connection area. For permanent outdoor installations, solder the wires to the pads and pot the entire joint area in clear silicone using a small mold or dam of electrical tape. Keep all power supply connections and splices inside a weatherproof junction box.
Yes. The strips run on 12V DC, which is the standard voltage of marine battery systems. No inverter or voltage converter is needed — connect the strip directly to a fused 12V circuit on the boat’s distribution panel. Add an inline fuse (5A for a single 5-meter reel) for safety. Use tinned marine-grade wire for all connections in saltwater environments to prevent corrosion, and seal every connection point with waterproof heat-shrink or marine-grade potting compound.
The transparent silicone coating causes negligible light loss — less than 5%, which is imperceptible to the human eye. The waterproof strip uses the same 5050 chips at the same current as the non-waterproof version and produces the same lumen output. The coating actually provides a slight diffusion effect that can soften the dot-pattern appearance of individual LEDs, which is an aesthetic benefit in many installations.
Clean the mounting surface thoroughly before applying the adhesive backing. For extra security in outdoor environments where temperature cycling may weaken adhesive, supplement with silicone adhesive mounting clips every 30–50cm or install inside an aluminum channel with mounting brackets. Aluminum channels also act as heat sinks and protect the strip from physical damage and UV exposure. Route all wiring through outdoor-rated conduit or cable channels, and keep power supply connections inside a weatherproof enclosure.
Yes. We carry waterproof 5050 RGB strips with the same IP65 silicone coating as our single-color waterproof strips. The RGB version uses a 4-pin connection (common anode plus red, green, and blue channels) and requires an RGB controller to select colors and effects. This is the ideal choice for outdoor entertainment areas, patio accent lighting, poolside color effects, event installations, and any outdoor application where you want dynamic color-changing capability with weather protection.
