GU5.3 Pool-Edge Spot: 12 V Lighting Around a Pool
These 12 V spots are installed by an electrician and run from a transformer. A pool lit from the deck looks better at night than one lit by a single wall floodlight, and it's safer: you can see the edge. Recessed spots set flush in the paving do that job. Near water, though, the rules tighten, and the one thing to get right is the voltage.
Short answer
This is a 10 cm recessed spot in 316 stainless steel with a frosted lens, made for 12 V and a GU5.3 (MR16) LED bulb up to 10 W. €25.90 each on lumihome.com (Nov. 5, 2026), bulb not included. It goes in the deck around a pool, not in the water: it is rated IP65, which keeps out jets and rain but not immersion. It needs a 12 V transformer, and all wiring near a pool must be done by a qualified electrician to your local rules. Your electrician decides which spots on the deck are allowed under local rules; check the installation instructions too. Underwater lights must be IP68.
Where it ships: Lumihome delivers to France, Belgium, Germany, Spain, Italy, the Netherlands and Portugal only. Not the UK, Ireland, Switzerland or anywhere outside the EU (as listed on lumihome.com on Nov. 5, 2026; check their site on the day).
Why 12 V, and what that means for you
- Low voltage near water. Electrical rules around pools (in France, the NF C 15-100 pool zones) limit what can go close to the water; safety extra-low voltage such as 12 V is the usual answer for lights in the deck.
- You need a transformer. The spots don't plug into 230 V. The transformer sits outside the restricted zones, and its rating sets how many spots you can run.
- Keep cable runs short. At 12 V, long thin cables lose noticeable voltage and the far lights look dimmer. Your electrician will size the cable for the distance.
- 316 stainless is the marine grade; it handles chlorinated and salt-water pool splash far better than common 201 or 304 steel.
How many spots per transformer
| Transformer | With 5 W LED bulbs | With 3 W LED bulbs |
|---|---|---|
| 24 W | 3 to 4 spots | 6 spots |
| 60 W | 9 to 10 spots | 16 spots |
Our rule of thumb is to load a transformer to about 80% of its rating. Lumihome sells a 12 V, 24 W transformer for its pool range; check its output type matches your bulbs (many GU5.3 LEDs accept both AC and DC, but not all).
Fitting them in the deck
- Plan positions on the pool's long sides, every 1.5 to 2 m, a little back from the coping so swimmers don't look straight into them.
- Drill 84 to 86 mm for the spot alone, or set the supplied 90 mm sleeve (90 mm deep) in concrete.
- Leave drainage below. A layer of gravel under each sleeve stops rainwater sitting around the fitting.
- Join the 20 cm lead in a waterproof connector rated for burial; the short tail is meant to be joined, not extended with tape.
- Choose bulbs no taller than 53 mm and no more than 10 W. Warm white (2700 to 3000 K) flatters stone and water at night.
Who it suits, who it doesn't
Good fit: homeowners in southern France, Spain, Portugal and Italy building or renovating a pool deck; terrace edges near water; anyone who wants flush, low-glare deck lighting.
Pick something else if: you want a light inside the pool (you need an IP68 underwater fitting); the deck is already laid and you don't want to drill; or you'd rather not deal with a transformer (for paths away from the pool, see GENOVA or Pyramide 1500).
Questions
Can it go underwater?
No. IP65 protects against water jets, not immersion.
Can I walk on it?
It sits flush and is designed for decks and paving. The product page doesn't give a load rating for vehicles, so keep it off driveways.
Is the bulb included?
No. Use a GU5.3 (MR16) LED bulb, 10 W maximum, up to 53 mm tall.
Can it be sent to the UK or the US?
No. Lumihome ships to France, Belgium, Germany, Spain, Italy, the Netherlands and Portugal only.
