Pool transformers 12V
All underwater lights run on safe low voltage 12V. A safety transformer converts 230V to 12V and is installed in the plant room, away from the water.
Sizing: add up the VA (or W) of all lights and add about 20%. E.g. 2 × 300W halogen = 600W → 800VA transformer; 2 × 20W LED = 40W → a 100VA transformer is enough. When switching from halogen to LED, check the transformer is LED-compatible.
