QCYYQYT 65W 120V LED Pool Light Bulb E26 6500LM 6500K Daylight — Retrofit for Pentair/Hayward Fixtures

QCYYQYT 65W 120V LED Pool Light Bulb delivers bright 6500K daylight output at 6500 lumens to replace high‑wattage halogen pool lamps while using far less energy.

This LED retrofit lamp is engineered for residential and commercial pool fixtures that accept an E26 base and 120V supply. With a compact 4.72 x 5.31 inch profile, it fits many Pentair Amerlite and some Hayward Astrolite housings (not compatible with 12V systems). Built with high‑output LED chips, an aluminum heat sink, a protective moisture coating and an internal fan, the bulb provides steady daylight illumination while aiming to reduce energy use and maintenance compared with legacy halogen or incandescent pool bulbs.

How bright is this LED compared with traditional pool bulbs?

The QCYYQYT 65W bulb produces about 6500 lumens at 6500K, giving a crisp daylight tone that visually matches much higher‑wattage halogen units. Its output is marketed as a practical replacement for many 200–800W traditional bulbs, depending on fixture optics and pool size.

• Rated output: 6500 lumens, daylight white (6500K).
• Power draw: 65W on AC 120V—significantly lower than equivalent halogen wattage.
• Effective replacement: commonly substitutes many 200–800W halogen/incandescent lamps.
• Color: neutral daylight for accurate water and tile color rendering.

Will this bulb work in my current pool light housing?

It fits fixtures that accept an E26 base at 120V and that have enough internal clearance for a 4.72 x 5.31 inch bulb. The lamp is not a sealed underwater unit, so it must be installed inside a properly waterproof pool light housing to prevent water exposure.

• Base: standard E26 suitable for many retrofit fixtures (confirm fixture socket).
• Voltage: AC 120V only — not for 12V systems or low‑voltage transformers.
• Size check: measure your lamp compartment before ordering to ensure fit.
• Installation: must sit inside an intact, waterproof luminaire housing.

How does the bulb manage heat and moisture in humid pool environments?

The bulb combines an aluminum substrate for heat dissipation, a built‑in fan to move air internally, and a moisture‑resistant coating on internal components. These design choices help reduce internal temperature and protect circuitry from humid conditions inside pool housings, but the bulb itself is not rated for direct water exposure.

• Thermal design: aluminum heat sink plus internal fan for active cooling.
• Protection: anti‑moisture coating on electronics to reduce corrosion risk.
• Durability: protective circuitry and driver to improve reliability.
• Note: still requires a watertight fixture for safe underwater use.

Are there any limitations or special precautions I should know?

This LED does not support dimming or color temperature adjustment and is incompatible with 12V/low‑voltage pool systems. Confirm physical dimensions and voltage compatibility before purchase; the bulb should always be used inside a sealed lamp housing designed for pool use.

• No dimming or color‑change features—fixed 6500K daylight white.
• Not suitable for 12V fixtures or transformer‑based setups.
• Not waterproof — must be mounted in a sealed underwater fixture.
• Recommended: verify lamp compartment size and socket type first.

Who is this for: The QCYYQYT 65W 120V LED Pool Light Bulb is aimed at pool owners, service professionals and facility managers who want high‑output daylight illumination with lower energy use and longer life than halogen bulbs, provided their fixture accepts an E26 120V lamp and remains fully sealed. It’s a practical retrofit option where bright, neutral white lighting is preferred and the fixture can protect the lamp from direct water contact.
