Best Pool Lights 2026: Solar Floating & RGB Underwater

Pool lighting used to mean calling an electrician. Now you have two genuinely good options that require zero wiring:

• Solar floating pool lights — inflatable balls that float, charge in sunlight, and glow automatically at dusk.
• RGB underwater pool lights — fully submersible rechargeable pool lights that sit on the pool floor and create vibrant colour effects.

Both are IP68 waterproof. Both are safe for swimming pools. But they serve different purposes — and choosing the wrong one is a common mistake.

In this guide, we break down what the specs actually mean, help you figure out which type suits your pool, and share honest real-world performance notes from our own testing.

Side-by-Side Comparison

Are Pool Lights Safe?

Short answer: yes. But it depends on what you buy.

The two things that determine safety are how waterproof the light is and what voltage it runs on. Both lights on this page run on a small sealed battery at 3.7V — about the same as a phone. There's no plug, no mains connection, nothing that could cause a shock in water. You can think of them more like a waterproof torch than a light fitting.

The waterproof rating to look for is IP68. That means the light has been tested for continuous submersion — not just splashing, not just rain, but actually sitting underwater. Both lights here carry that rating. If a light just says "waterproof" without a number, that's not a specification — don't use it in a pool.

Chlorine won't damage either light during normal use. Just give them a rinse with clean water after each session to keep the seals in good shape.

Are Solar Pool Lights Worth It?

For most pool owners, yes — and here's the honest version of why.

The main appeal is that they just work without you doing anything. Leave them in the pool during the day, and they switch on automatically when it gets dark. No app, no timer to set, no cable to plug in. For everyday evening use, that convenience is hard to beat.

At $45.99 for a 2-pack, they're also genuinely affordable. And since they run on solar, the ongoing cost is zero — compared to a hardwired pool light that adds to your electricity bill every month.

Where they fall short is consistency. After a few cloudy days in a row, the battery doesn't get a full charge and the runtime drops. They're also warm white only — no colour options. And because they float, they drift around rather than staying in one spot.

In our own testing with two lights in a standard backyard pool, the 60% brightness setting gave a comfortable, even glow across the whole water surface. At full brightness, it was bright enough to read poolside. A full charge on a sunny day took around 6.5 hours.

If you want lights that come on every evening without thinking about it, solar floating lights are worth it. If you need guaranteed brightness for a specific event — like a party — pair them with the USB-rechargeable RGB lights below.

Best Pool Lights for Parties: What Actually Works

A pool party is a different situation from everyday evening lighting, and it calls for a different approach.

The problem with relying on solar lights for a party is that you can't control how much sun there's been in the days before. If it's been overcast all week, the battery might not be full when you need it. For a party, you want something you can charge the day before and know it'll run all night — that's the USB-rechargeable RGB lights.

The colour effect also makes a bigger impression. RGB lights sit on the pool floor and send colour upward through the water — the whole pool glows. It's visible from across the garden, and it's the kind of thing guests notice and ask about. Warm white floaters are lovely for a quiet evening; RGB underwater lights are what you want when you're trying to create a moment.

For a full party setup, the 4-pack ($64.99) covers a standard pool properly. Two lights works, but four gives you that fully immersive effect. Many customers use both types together — the floaters add movement on the surface while the RGB lights handle the colour below. Total setup time: under 5 minutes.

Rechargeable Pool Lights: The Practical Guide

Both options here are rechargeable — they just charge in different ways, and that matters depending on how you use them.

The solar floating lights charge themselves while they're in the pool or sitting in the sun. No cables, no action needed. On a sunny day, a full charge takes 6–8 hours. On an overcast day, it still charges — just more slowly, so allow a bit more time.

The RGB lights charge via USB, which takes about 3–4 hours and gives you up to 20 hours of runtime. The advantage is that it doesn't depend on the weather — charge them the night before and they're ready to go regardless of what the sky's been doing.

Both use lithium batteries rated for 500+ charge cycles, so they'll last well over a year of regular use. If you're storing them over winter, keep them at around 40–60% charge rather than fully flat or fully charged — that extends battery life.

Running cost comparison, for context:

• Solar floating lights: $0 per charge
• RGB USB lights: about $0.01 per full charge
• A typical hardwired pool light running 6 hours a night: around $26 per year in electricity
