Pool Underwater Lighting Guide — LED vs Halogen, Types & Installation Tips
Pool lighting transforms a swimming pool from a daytime feature into an all-night centerpiece. But beyond aesthetics, pool lighting involves critical safety considerations.
## Safety First: The 12V Requirement
All underwater pool lights must operate at 12V low voltage, not 220V mains power. This is a safety requirement enforced by Egyptian electrical standards.
## LED vs Halogen — Why LED Wins
- Energy: An 18W LED produces the same brightness as a 300W halogen. Savings of over 90%.
- Lifespan: LED lasts 25,000–50,000 hours vs 2,000–4,000 hours for halogen.
- Heat: LED produces minimal heat. Halogen heats the water.
- Colors: LED can produce white, blue, green, red, and RGB color-changing effects.
## How Many Lights Does Your Pool Need?
- Residential pools: 1 light per 15–20 m² of pool surface area
- Hotel/resort pools: 1 light per 10–12 m²
- Olympic/competition pools: Specific lighting standards apply
Example: A 50 m² residential pool needs 3–4 underwater lights.
