Quick Answer
To protect LED lights from water exposure in outdoor use, you can use a waterproof enclosure, apply a waterproof coating, or select LED lights with an IP67 or higher rating. This will prevent corrosion and ensure the lights remain functional.
Understanding IP Ratings
When selecting LED lights for outdoor use, it’s essential to choose ones with an IP (Ingress Protection) rating of IP67 or higher. This means the light is protected against dust and water immersion up to 1 meter for 30 minutes. Look for the IP rating on the manufacturer’s datasheet or product description. Some common IP ratings for LED lights include IP55 (protected against dust and low-pressure water jets), IP65 (protected against dust and low-pressure water jets, with limited ingress in certain operating positions), and IP66 (protected against powerful jets of water).
Applying a Waterproof Coating
If you already have LED lights without an IP67 rating, consider applying a waterproof coating to protect them from water exposure. You can use a silicone-based sealant like 3M 5200 or a polyurethane-based clear coat like Dupli-Color Clear Coat. Apply the coating according to the manufacturer’s instructions, making sure to cover all exposed electronics and connections. This will provide a temporary solution until you can replace the lights with a more durable, waterproof option.
Water-Resistant Enclosures
Another way to protect LED lights from water exposure is by using a waterproof enclosure. You can purchase a pre-made enclosure online or create your own using a waterproof housing like a NEMA 4X box. Make sure the enclosure is specifically designed for outdoor use and can withstand the elements. When installing the LED lights inside the enclosure, use a waterproof sealant to ensure all connections are secure and protected from water ingress.
