White moonlight LED lamp for swimming pool, solar powered, with magnet or adhesive
Professional-grade solar underwater LED light for pools and fountains, Moonlight model: a soft white glow that mirrors the moon on the water. Not a supermarket light: OSRAM Opto LED, a real 3200 mAh lithium battery, 320 lm, up to 7 hours of light per hour of sun. No wiring, no masonry, no electricity bill.
Sealed housing built to last season after season in chlorinated and saltwater. Available in two mounting versions: Magnet (liner pools and steel walls) or Adhesive (tiles, polyester, painted surfaces). Choose the mode in the field below.
The UWST1 Moonlight white solar pool light lights up pools, fountains and ponds with no wiring, no drilling and without draining the water, spreading a soft white moonlight-effect glow. It is a professional-grade product built to last for years: it recharges by itself during the day through high-efficiency polycrystalline solar cells and switches on automatically at dusk, turning every evening swim into an elegant, relaxing experience.
Not all solar pool lights are the same
The market is full of cheap floating lights that promise a lot and last a single season: no-name LEDs that fade in weeks, batteries with inflated capacity, housings that yellow and flood at the first winter. The UWST1 Moonlight follows a different logic: real components, real waterproofing and constant performance over time. If you just want the cheapest lamp possible, this is not the right product; if you want a refined wireless pool light that still works several seasons from now, it is.
Why the Moonlight costs more (and why it pays off)
- OSRAM Opto high-power LED: 320 real, constant lumens — not a declared peak. It truly lights 15–20 m² of water surface with a natural white light.
- 3200 mAh lithium battery with genuine capacity: about 7 hours of light per sunny day, with a real 1:1 charge-to-runtime ratio.
- Patented lighting system (U.S. Pat. 10132455 – European Patent EP 3118392) and made in Europe with high-quality materials.
- Sealed for chlorine and saltwater: it withstands prolonged exposure season after season, not just the first months.
- Ultra-slim and ready to use: 308 mm across, only 12 mm thick; it ships in a ready-made box and installs in under 5 minutes without tools.
How much you really save
Traditional wired underwater lights require masonry, electrical conduits and often draining the pool: a job that can cost several hundred euros in materials and labour. The Moonlight installs in under 5 minutes, with no electrician and no tools, at zero installation cost and zero running cost. And compared with a cheap lamp you replace every year, a light built to last several seasons pays for itself.

How many lights do you need?
Each unit lights about 15–20 m² of water surface:
- Pools up to 5 × 3 m → 1 light
- Pools from 8 × 4 m to 10 × 5 m → 2 lights
- Pools 12 × 6 m → 3 lights
How to install it
Choose the version that best fits your pool:
- Magnet: for above ground pools and liner pools with steel or galvanised walls (Intex, Bestway, Gre and similar). The lamp clips on with the magnet and comes off without tools, ideal to store it off-season too.
- Adhesive: for tiles, polyester, PVC liner and painted surfaces. Includes a syringe of special underwater polymer, resistant to chlorine and saltwater.
Installation is identical either way: place the lamp 20–30 cm below the waterline on the sunniest wall to maximise solar charging.
Frequently asked questions
Why does it cost more than a supermarket light?
Because it uses a professional OSRAM Opto LED, a 3200 mAh lithium battery with real capacity and a sealed housing made in Europe and patented. Cheap lamps use no-name LEDs and batteries that lose brightness and sealing within a season: the Moonlight is built to last for years, keeping 320 lm constant and resisting chlorine and saltwater. A higher price buys better components and a much longer life.
How long does it last over time?
Unlike cheap floating lights that often stop working after a few months, the Moonlight is built to last season after season. The lithium battery keeps good capacity over time and the sealed housing protects the electronics from chlorine and saltwater. The product is covered by the legal warranty of conformity.
What is the difference between the white Moonlight and the blue DeepBlue?
The technology is identical (OSRAM LED 320 lm, 3200 mAh battery, 7-hour runtime): only the light colour changes. The Moonlight gives a soft white glow reminiscent of moonlight, ideal for natural, elegant lighting; the DeepBlue tints the water blue for a more dramatic effect. Many customers combine both in the same pool.
Does it survive robotic pool cleaners?
Yes. Both the adhesive and the magnet are designed to withstand automatic cleaners passing over them — there is no need to remove the light for cleaning.
Can I leave it installed over winter?
Yes, it can stay installed through winter, even under a winter cover. Only remove it if the pool is drained or in case of hard frost. To store it out of the water, charge it a few hours before putting it away and refit the protective magnet to keep the battery from discharging.
Do I need to drain the pool to install it?
No. The Moonlight installs directly on the wall of the full pool, without draining the water. The underwater adhesive included bonds to any surface (tiles, polyester, liner, painted) even underwater. The magnet version clips on instantly with no glue.
Does it work in saltwater pools?
Yes. The Moonlight works with both traditional chlorinated water and salt (sodium chloride) systems. The sealed housing withstands prolonged exposure to both.
How many hours of runtime at night?
The ratio is 1:1 — every hour of sun stored during the day gives one hour of night light. A full summer day of sun (6–8 hours) gives 6–8 hours of runtime. The 3200 mAh lithium battery delivers about 7 hours of continuous light on average, switching on and off automatically via the dusk sensor.
