Filament A15 Bulb 4.5 Watt 450 Lumens 2700K 80 CRI Dimmable Medium E26 Base Energy Star Rated Amber Glass 120V

Where is an A15 bulb typically used compared to an A19?

An A15 is a smaller “appliance/compact” bulb shape often used where the fixture has limited clearance—such as ceiling fans, small decorative shades, sconces, and some enclosed glass fixtures. This model still uses a standard medium E26 base, so the key check is physical fit (1.88" diameter, 3.46" height).

How bright is 450 lumens for an A15?

At 450 lumens, it’s commonly used for ambient or decorative lighting in smaller fixtures rather than high-output general illumination. In multi-lamp fixtures (like some ceiling fans), multiple A15 lamps are often used to reach the desired overall light level.

What does “filament” LED with amber glass change in appearance?

LED filament construction is designed to mimic the look of traditional incandescent filaments, and amber glass warms the visual appearance of the lamp and softens glare. The result is typically a more decorative, vintage-style look rather than a neutral white presentation.

What should I consider for dimming compatibility with LED filament lamps?

It is dimmable, but performance depends on the dimmer type and the fixture environment. For smoother dimming with fewer artifacts (flicker, shimmer, or drop-out at low levels), use an LED-rated phase dimmer and verify compatibility with the specific dimmer model.

What do the UL and Energy Star listings indicate?

UL Listed indicates the lamp meets common safety requirements for the intended use. Energy Star rating indicates it meets efficiency and performance criteria used in that program, which can be relevant for energy-focused projects or procurement standards.
