Blue LED solar-powered pool lamp with magnet or adhesive
Solar underwater blue pool light — the only patented system that installs directly on a full pool wall in under 5 minutes, with no wiring, no drilling, and no draining required. Powered exclusively by its built-in solar cells: OSRAM LED 320 lm, lithium battery 3200 mAh, up to 7 hours of runtime per night.
Compatible with chlorinated and saltwater pools. Choose your installation: Magnet (liner & steel-wall pools) or Adhesive (tile, fiberglass, polyester, painted). No electrician needed.
If your pool has no light — or your old wired fixture just died — the UWST1BLUE solar underwater pool light is the simplest fix on the market. No trenching, no conduit, no electrician, no draining. Just peel, press, and swim. It charges itself all day underwater using its built-in polycrystalline solar cells, then switches on automatically at dusk.
This is not a floating decorative toy. It is a fixed, wall-mounted underwater spotlight — the same concept as a traditional wired pool light, but completely wireless and self-powered. U.S. Patent No. 10132455 · European Patent EP 3118392. In production since 2015, sold in over 20 countries.
Why pool owners in the US choose the UWST1BLUE
Replacing a traditional wired pool light in the US typically costs $500–$2,000 in parts and labor, requires draining the pool, and may involve cutting into the pool shell. The UWST1BLUE eliminates every one of those steps. It sticks directly to the submerged wall — tile, fiberglass, plaster, vinyl liner, polyester — and starts working the same day. Zero installation cost. Zero electricity cost. Zero maintenance.

How many lights do I need?
Each unit covers approximately 160–215 sq ft of water surface. General sizing guide:
- Pool up to 15 × 10 ft → 1 light
- Pool 25 × 12 ft to 33 × 16 ft → 2 lights
- Pool 40 × 20 ft → 3 lights
Magnet vs. Adhesive — which version is right for you?
- Magnet version: designed for above-ground liner pools with galvanized steel walls. Snaps on instantly, removes without tools or residue. Perfect for seasonal removal.
- Adhesive version: works on any surface — tile, plaster, fiberglass, polyester, painted concrete, PVC liner. Includes a syringe of special underwater-cure polymer that bonds directly through water, no draining required.
In both cases: install at 8–12 inches depth on the sunniest wall of the pool for maximum daily charge.
Frequently Asked Questions
Do I have to drain the pool to install this light?
No. The UWST1BLUE installs directly on the submerged pool wall while the pool is full of water. The adhesive version uses a specially formulated underwater polymer that cures and bonds through water — no draining, no drying, no waiting. The magnet version simply snaps onto steel liner pool walls instantly.
Can I use this to replace a dead wired pool light without hiring an electrician?
Yes — this is one of the most common use cases. If your existing wired pool light has failed and you want to avoid the cost of professional electrical work (typically $500–$2,000 in the US), the UWST1BLUE is a fully self-contained alternative. No wiring, no conduit, no permits needed. It mounts on the wall surface and operates completely independently from your pool's electrical system.
Does it work in a saltwater pool?
Yes. The UWST1BLUE is fully compatible with both chlorinated and saltwater (NaCl) pool systems. The housing and adhesive are engineered for long-term submersion in both chemical environments. No additional treatment or protection is needed.
Will my robotic pool cleaner knock it off the wall?
No. Both the adhesive bond and the magnetic hold are strong enough to withstand contact with standard robotic pool cleaners. You do not need to remove the light before running your robot. Multiple users with Dolphin, Polaris, and similar robots report no issues.
How long does the battery last and how bright is it at night?
The 3200 mAh lithium battery gives a 1:1 charge ratio — one hour of direct sunlight equals one hour of nighttime light. On a typical summer day with 6–8 hours of sun, you get 6–8 hours of runtime. At 320 lumens through the OSRAM high-power LED, the light is comparable in brightness to standard wired pool lights. The dusk sensor activates it automatically every night without any manual input.
Can I leave it in the pool over winter?
Yes, if your pool stays filled. The light can remain installed through winter even under a pool cover, as long as it is not exposed to hard freezes. If you winterize and drain your pool, remove the light first, recharge it fully, and reattach the protective magnet to the back before storage — this keeps the battery conserved until next season.
