LED strip underwater

I am currently working on a project that involves placing an LED strip at the bottom of a pool. This strip will send patterns of light along the surface of the pool. After researching various options, I found a suitable 5V APA-102 32 LEDs/meter IP68 (submersible waterproof) LED strip. This can be controlled using an Arduino Due with the FASTLED library. The LED strip will span the length of the pool (25 meters), but I will only power 28 LEDs at a time. As each LED consumes 60mA at full brightness, a 5V 2A power supply will suffice. Additionally, to mitigate voltage drop, I plan to power the LED strip every 5 meters.

With competitive pricing and timely delivery, BLUE DIAMOND sincerely hopes to be your supplier and partner.

Do you think this installation is safe for a pool environment? I am concerned about potential wiring exposure, which could create shorts and pose a risk of injury to swimmers. What suggestions can you provide to enhance the system's safety?

According to the manufacturer, IP68 indicates that the strip is resistant to immersion at a depth of at least 1m (3.2 feet) or more. Therefore, it should be safe for pool use. I recommend using adhesive heat shrink on the wire connections and sealing the ends.

A 5V power supply is safe for use. You could even place the leads in your mouth without any adverse effects (aside from potential discomfort later). However, I strongly advise incorporating a fuse that will blow if excessive current is drawn. You can purchase fuses and fuse holders from retailers like Amazon. Use a 2A fuse with a power supply rated slightly above 2A to ensure proper function. Your power supply needs to generate enough current to activate the fuse; otherwise, it may limit instead of the fuse blowing.

LED strip lights are popular in households and offices, but there are many situations where waterproof variants are necessary, such as in bathrooms, kitchens, outdoor areas, swimming pools, and saunas.

Different waterproofing levels exist for LED strips. Knowing how to choose the right one is crucial. This article will provide guidance on installation, cutting, and welding waterproof LED strip lights.

First, confirm the intended installation location for the strips. Non-waterproof strips are suitable for bedrooms or living rooms, where exposure to water or humidity is minimal. Alternatively, consider using IP62 or IP65 rated strips in those areas to prevent dust and simplify future cleaning.

For kitchens or bathrooms, it's essential to use IP62 or IP65 waterproof strips. Unless these areas are frequently sprayed with water, installing IP67 or IP68 strips is not necessary.

If installing an outdoor LED strip that may be exposed to heavy rain but not submerged, we recommend an IP67 or IP68 rated strip.

For installations within water, such as in swimming pools or fish tanks, choose an IP68 rated strip for maximum protection.

When considering waterproofing materials, the three most popular options are:

• Epoxy Resin
• PU Glue
• Silicone Glue

4.1 Epoxy Resin

Epoxy resin is cost-effective, easy to handle, and low in toxicity. It is a common waterproofing material for many affordable LED strips available on the market. However, it has significant drawbacks. Its poor heat conductivity may reduce the lifespan of the strip lights and can yellow after approximately six months, affecting their color temperature. Additionally, epoxy resin is sensitive to temperature extremes, hardening and cracking in conditions below 0°C.

4.2 Polyurethane Glue

PU glue costs more than epoxy resin but offers better yellowing resistance, low-temperature stability, and improved thermal conductivity. That said, it is toxic, as it produces harmful compounds during curing that emit a strong odor, detrimental to health. It is also not suitable for high-temperature environments above 80°C.

4.3 Silicone Glue

Silicone glue is the most expensive option but is environmentally friendly and retains the advantages of PU and epoxy. It offers excellent heat and low-temperature resistance, performing well in environments ranging from -50°C to 300°C. Silicone LED strips are ideal for use in saunas and refrigerators, while also maintaining long-term color stability and thermal conductivity. For high-power (over 20W) applications, adding aluminum channels is recommended for effective heat dissipation.
