The NorthLux™ A21 bulb is the easiest way to get started with premium-quality art studio lighting.

The A21 bulb is a more powerful version of our A19 lamp, providing the equivalent brightness of 100 watt incandescent light bulbs. Only slightly larger, the lamp fits in a wide variety of lamp fixtures such as clip-on easel lamps, table lamps, floor lamps and more.

Our A21 bulbs emit 1600 lumens with a light spectrum that is unparalleled in similarity to natural daylight. The 5000K (D50) color temperature matches noon sunlight, while the 6500K (D65) matches north-facing skylight, both of which achieve a 95 CRI and 80+ R9 rating.

This light bulb is a must-have for anyone in the visual arts, allowing them to confidently see and perceive color the same as they would under natural light.

These light bulbs are built with Waveform Lighting's latest LED technology and utilize premium quality LED components for the industry's best in light quality, consistency and longevity.
