Technical FAQ Deep-Dive

What is an A21 bulb and where is it typically used?

A21 refers to the lamp shape/size (about 2.625" diameter class). It’s commonly used in larger table lamps, high-output ceiling fixtures, garage/utility fixtures, and other applications that benefit from higher lumen output than a standard A19.

How bright is 1,600 lumens for an A21 lamp?

1,600 lumens is a high-output “general service” level often chosen when you want strong ambient light from a single lamp—useful for larger rooms, higher ceilings, or fixtures with diffusers that reduce delivered light.

What does 90+ CRI change compared with standard LED bulbs?

90+ CRI improves color rendering compared with typical 80 CRI lamps, which can make paint colors, wood tones, and skin tones look more accurate—especially noticeable in kitchens, retail areas, and hospitality interiors.

How do I choose between 3000K, 4000K, and 5000K?

3000K is warm-neutral, 4000K is a common neutral white for work areas, and 5000K is cooler and often selected where higher contrast is preferred. Confirm whether the CCT is fixed per model/variant or selectable on the lamp.

What do JA8 and Energy Star mean, and what should I know about dimming?

JA8 and CEC compliance are commonly specified to meet California efficiency/performance requirements for certain projects, and Energy Star indicates additional efficiency and performance criteria. For dimming, use an LED-rated phase dimmer and verify compatibility if the installation is sensitive to flicker or low-end drop-out.
