12v 5050 WaterProof LED Strip
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.
