Buying Guide
What should you consider when choosing an underwater pool light bulb?
- Voltage and base compatibility: Most 120V pools use E26/E27 bases. Confirm your fixture type before purchasing to avoid incompatible fittings.
- LED vs halogen: LEDs dramatically reduce energy use and run cooler. Halogen bulbs emit warm hues but cost more to run and have shorter lifespans.
- Brightness and color: For vibrant underwater effects, RGB LEDs offer color options; daylight white LEDs provide bright, even illumination. Consider the pool size and desired ambiance when selecting lumens.
- Durability and heat management: Bulbs with aluminum cooling or robust housings last longer in wet environments. Check for notes on heat dissipation.
- Installation: Look for plug-and-play designs that fit common pool housings. Some bulbs require simple screw-in replacement; others may need fixture-specific adapters.
- Maintenance and compatibility: Ensure the bulb is compatible with your pool’s existing lighting fixture and controller (especially for color-changing models).
