COOLWEST PAR56 12V LED Pool Light Bulb 36W 4320LM 6000K Daylight White — E26 Fit for Inground Fixtures

The COOLWEST 12V 36W PAR56 LED pool bulb is a high-output daylight white replacement designed to fit most inground pool fixtures with an E26/E27 medium base, delivering bright, energy-saving illumination for underwater installations.

This LED lamp replaces older incandescent or halogen PAR56 pool bulbs to give pools and water features a crisp, long-lasting white light. Built for low-voltage (AC/DC 12V) pool systems, it produces a daylight-white color temperature ideal for clear nighttime visibility while cutting energy use and bulb-change frequency. The unit is intended for use inside the pool housing — the lamp itself is not waterproof, so a proper sealed gasket and fixture cover are required to prevent leaks.

How bright is this COOLWEST LED and what do the specs mean for my pool?

This model outputs approximately 4320 lumens (manufacturer lists high-lumen performance around 3960–4320LM) at a 6000K daylight-white color, using 36 watts of power. It replaces much higher-wattage incandescent bulbs, giving a cleaner white light with significantly lower energy draw.

• Light output: ~4320 lumens, daylight 6000K for crisp underwater visibility.
• Power use: 36W vs. 200–600W older bulbs — large energy savings.
• Base: E26/E27 medium screw base fits most PAR56 housings designed for medium bases.
• Voltage: AC/DC 12V — confirm your pool transformer is 12V before ordering.

Will this LED physically fit my pool light housing and is it easy to install?

The bulb measures roughly 6.7 inches in diameter and 5.3 inches long, matching the common PAR56 profile and medium base used by many pool fixtures. Replacement is straightforward when you follow basic safety steps and use a new gasket to maintain a watertight seal.

• Dimensions: 6.7" diameter × 5.3" length for most inground PAR56 housings.
• Compatibility examples: Fits many Hayward, Amerlite, Sta-Rite, SwimQuip housings; check small spa fixtures separately.
• Installation: remove fixture lid, disconnect and reconnect terminals, seat bulb, replace gasket and lid, then secure screws.
• Tip: buy a replacement gasket at the same time to prevent leaks — lamp is not waterproof alone.

What safety, longevity, and certification details should I know?

COOLWEST designs this LED with common safety approvals and extended life expectations relative to incandescent options. The lamp carries CE, RoHS and FCC markings and is rated for long service life, reducing how often you need to open the housing for maintenance.

• Certifications: CE, RoHS, FCC for regulatory compliance.
• Lifespan: LEDs typically last far longer than incandescent bulbs; expect tens of thousands of hours.
• Service: 12 months of free replacement by the seller and a 30-day refund policy where applicable.
• Water handling: Lamp is not sealed — rely on fixture gasket and cover to keep water out of the housing.

Who is this replacement bulb best for? Homeowners and pool professionals looking to upgrade older PAR56 halogen or incandescent pool lights to a bright, energy-efficient daylight-white LED will find this COOLWEST bulb useful. It suits inground pools, large water features, and many public or hospitality installations that use 12V medium-base housings. If your fixture uses a smaller spa-specific lamp or a 120V system, confirm compatibility before purchasing. Always replace the housing gasket during bulb swaps to ensure a watertight seal and safe operation.
