Pool Lighting Design Guide
Underwater fixtures, warm white as the base, RGB as a scene. How to light a pool that looks elegant year-round.
Pool Lighting in Two Parts
A pool needs underwater lighting (atmosphere and visibility) and surround lighting (safety and circulation). Each is a separate design.
Underwater
- IP68 niche fixtures, low voltage (12V or 24V)
- Spaced for even glow, not hot spots
- Warm white 2700K–3000K as the daily default
- Optional RGB on a separate circuit for events
- CRI 80+ minimum
Surround
- Low bollards or recessed step lights at 5–15 lux
- No glare into the pool from above
- 2700K, warm
- PIR or scene control
Common Mistakes
- RGB-only pools, look dated quickly
- Single bright surround floodlight, glare and pool reflection
- Mains-voltage fixtures, never appropriate
- Cool CCT, the water looks chlorinated
Professional Recommendation
Warm white as the daily look. RGB optional for events. Always IP68 and low voltage.

Frequently Asked Questions
How many underwater fixtures does a pool need?+
Typically one fixture per 4–6 m² of water surface, but verify with photometric data per product.
Is RGB underwater safe?+
Yes if IP68 and low voltage. Quality matters more than brand.
