You’ve got a few options, and it really comes down to power and mounting:

• Floating solar lights: Great for quick ambiance in above‑ground or inground pools and ponds. No wiring, just charge in the sun and place on the water.
• Submersible LED lights: Battery‑powered or rechargeable, often with suction cups or magnets. These work in both pool types; magnets need a metal surface, suction cups like smooth walls.
• Wired/plug‑in lights: Designed for more permanent installs (some state AC 120V or low‑voltage). Check cable length, voltage, and mounting requirements. Hardwired installs should be handled by a licensed professional.

Always review product specs on Walmart’s product pages for pool type compatibility and installation notes before you buy.

Look at the IP rating in the specs to match how you plan to use the light:

• IP68: Typically used for continuous submersion, making it a common choice for underwater pool lights.
• IP67: Helps with temporary submersion; more for brief dips than long soaks.
• IP65/IP66: Splash‑resistant for surfaces or floating units that get wet but may not stay submerged.

For underwater placement, IP68 is generally preferred, but always confirm the manufacturer’s stated depth/duration guidance. Also check details like sealed battery compartments, O‑rings, and lock tabs. After heavy chemical treatments, removing lights and rinsing with fresh water can help longevity. Specs and customer reviews on Walmart’s product pages provide helpful context.

Yes—solar pool lights use built‑in panels to charge during the day, then run from their internal batteries at night. How long they glow can vary by sunlight exposure, battery capacity, and the color/mode you choose.

• Placement: Give the solar panel full, direct sun and keep it clear of shade and debris.
• Mode selection: Steady, brighter modes may use more power than gentle fades.
• Seasonal conditions: Shorter winter days and cloudy weather can reduce runtime.

Many models are designed for pools, ponds, and patios, but runtimes differ. Checking the product description and reviews on Walmart’s product pages can help you gauge typical overnight performance for a specific light.

Many underwater pool lights are versatile, but it’s best to verify the intended use in the listing:

• Waterproof rating: For continuous submersion (ponds, hot tubs), look for IP68 and confirm the manufacturer’s guidance.
• Temperature and chemicals: Hot tubs run warmer and may use stronger sanitizers. Check any stated temperature or chemical compatibility in the specs.
• Mounting: Suction cups prefer smooth surfaces; magnets need metal. Floating styles are easy for ponds and pools.
• Wildlife and flow: In ponds, avoid placing lights where they could disturb fish or block pumps.

If the product description notes pools/spas or ponds, you’re likely good to go. When in doubt, consult the manual on the Walmart product page.

A few quick steps can help with performance and safety:

• Prep the light: Check the battery compartment or charging port, and make sure seals/O‑rings are clean and seated before submerging.
• Test first: Turn the light on out of water to confirm it’s working, then submerge.
• Mounting surface: Clean smooth walls for suction cups; verify metal for magnets. Avoid placing lights over returns, drains, or near skimmers.
• Remote control: Keep the remote dry and follow pairing instructions. Range may vary.
• Electrical models: For wired or hardwired units, use a licensed professional and follow local codes.

Always follow the product manual, and review installation details on Walmart’s product pages for the specific light you choose.
