MOSELNY LED Spa Bulb PAR20 E26 15W 1500lm 6000K Daylight White — Energy‑Saving Inground Spa Replacement

MOSELNY’s 15W 120V LED spa bulb is a daylight-white (6000K) PAR20 E26 replacement designed to fit many inground spa fixtures and deliver bright, energy-efficient underwater light.

This LED spa light is engineered as a direct white-light substitute for traditional halogen spa bulbs, offering 1500 lumens at only 15 watts. It is made to work with standard 120V underwater housings (such as many Pentair and Hayward covers), provides a cool daylight color, and simplifies maintenance with an easy screw-in E26 base. Read the sizing and electrical notes carefully to confirm compatibility before purchasing.

Will this LED bulb fit my inground spa fixture?

Check the fixture’s bulb size and base type first. The MOSELNY bulb is a PAR20/ R20-R40 style with an E26/E27 base, 2.65 inches in diameter and 3.15 inches in length, so it fits many popular spa light covers that accept PAR20-sized lamps.

• Diameter: 2.65 inches (fits R20–R40 covers)
• Length: 3.15 inches (verify clearance inside housing)
• Base: E26/E27 screw-in — compatible with standard medium base sockets
• Pro tip: measure interior depth and gasket location before ordering

Can I replace a 100–300W halogen with this 15W LED bulb?

Yes — this LED provides high lumen output at much lower wattage, making it a common replacement for 100–300W halogen spa bulbs when the housing supports 120V input. It yields about 1500 lumens (daylight-white), while drawing just 15 watts.

• Lumen output: 1500 lm for bright white illumination
• Wattage: 15W, replacing higher-watt halogen models
• Energy class: A++ for reduced power draw
• Expected: large energy savings versus halogen counterparts

What electrical and waterproof precautions should I know?

This MOSELNY bulb requires a 120V supply; it will not work with 12V systems. The LED lamp itself is not standalone waterproof — it must be installed inside your existing underwater light housing with a properly sealed cover and a new gasket to prevent leaks.

• Input voltage: 120V only — incompatible with 12V fixtures
• Not waterproof on its own — use original fixture cover and gasket
• Replace gasket when re-installing to maintain watertight seal
• Certifications: CE, RoHS, FCC for safety and compliance

How bright and what color is the light in the spa?

The bulb produces a crisp daylight-white output at 6000K, suitable where neutral-to-cool white illumination is preferred for clarity and contrast underwater. It’s a single-color white lamp controlled by your existing wall switch — no remote or color control included.

• Color temperature: 6000K daylight white
• Single color output — switch-controlled (no remote)
• Uses OSRAM LED chips for consistent brightness
• Designed for clear, high-contrast underwater lighting

Who is this for: The MOSELNY 15W 120V LED spa bulb is ideal for homeowners or service technicians who need a bright, energy-saving white replacement for higher-wattage halogen spa lights in 120V inground fixtures. Choose this bulb if your housing accepts PAR20 / R20–R40 sizes, uses an E26/E27 socket, and you prefer a daylight-white (6000K) output with lower power consumption. If your system runs on 12V or you require colored/remote-controlled lighting, consider a different model that matches those specs.
