As night falls, the illuminated waters of pools and spas transform into shimmering oases, creating tranquil retreats. But when replacement becomes necessary, many homeowners face confusion: Is this a pool light or a spa light? Understanding the key differences ensures you select the proper fixture to maintain your aquatic haven's brilliance.
The most immediate difference lies in dimensions. Pool lights typically feature larger diameters, with common sizes measuring approximately 10¾ inches (including face rings). Spa lights are more compact, usually around 6 inches in diameter (with face rings). While exceptions exist—some installations use spa lights in pools or vice versa—accurate measurements of your existing fixture prevent compatibility issues.
Electrical requirements form another crucial differentiator. Local electrical codes dictate whether your fixture operates at 120V (line voltage) or 12V (low voltage). The latter requires a separately purchased transformer to convert 120V household current. Always verify your system's voltage specifications before purchasing replacements.
Pool lights generally range between 300-500 watts, though 12V models typically cap at 300 watts due to their lower voltage. Spa lights, being smaller, rarely exceed 100 watts regardless of voltage.
Removing the fixture housing often reveals manufacturer labels containing essential information—model numbers, bulb types, voltage, and wattage specifications. These details significantly simplify the replacement process.
With these guidelines, identifying and selecting appropriate aquatic lighting becomes straightforward, ensuring your pool or spa maintains its nighttime allure for years to come.
