Circline LED Bulbs: Circular Fluorescent Replacements

A circline light bulb is a unique, circular lamp designed as a direct round fluorescent replacement for specialty ceiling fixtures. These circular light bulbs are typically T9 diameter (9/8ths of an inch) and provide an even, diffuse ring of light. Our modern circline LED bulb options eliminate the humming, flickering, and buzzing associated with old fluorescent rings, offering immediate, stable illumination.

Key Advantages of LED Circline Lamps

Circline LED lamps revitalize older fixtures with modern efficiency and light quality.

• Unique Aesthetic: The circle light bulbs provide a distinct, uniform ring of light, perfect for flush mount and contemporary ceiling fixtures.
• Instant Activation: Unlike fluorescent circline tubes that require warm-up time, circline LED bulbs offer instant-on light with full brightness.
• Compatibility: Designed for simple round fluorescent replacement in standard fixtures, often utilizing the same base type (e.g., G10q or 4-pin).
• Longevity & Safety: Eliminates the need for ballast maintenance and contains no mercury, making disposal easy.

Circline Sizing and Where to Install

The circular shape is essential for fixtures requiring wide, uniform coverage from a single lamp.

• Common Diameters: The most frequent sizes are 8-inch, 12-inch, and 16-inch diameters, which correspond to the old fluorescent T9 circline sizes.
• Base Types: Circline lamps primarily use a G10q (4-pin) base, requiring careful wiring when performing a ballast bypass.
• Ceiling Fixtures: The staple use for circular light bulbs in kitchens, hallways, and utility rooms where the fixture housing is round.
• Magnifying Lamps: The even, shadow-free light provided by the circle light bulbs makes them ideal for professional magnifying lamps used in hobbies, crafts, and medical settings.
