Technical FAQ Deep-Dive

What is a GU24 base and where is it commonly used?

GU24 is a bi-pin, twist-lock base used on some fixtures to prevent using standard screw-base lamps. It’s common in certain ceiling fixtures, flush mounts, and downlight cans that were specified for GU24 for energy-code compliance. This lamp will only fit GU24 sockets (it is not an E26 screw base).

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

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

What does 90+ CRI change in real use?

90+ CRI improves color rendering compared with standard 80 CRI lamps, which can make finishes, materials, and skin tones appear more accurate—especially noticeable in kitchens, retail areas, and hospitality interiors.

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

3000K is a warm-neutral tone often used in customer-facing or residential-style interiors, 4000K is a common neutral white for offices and corridors, and 5000K is a cooler white often used where higher contrast is preferred. Confirm how CCT is selected on this lamp (fixed vs selectable by a switch or ordering variant).

What do JA8 and Energy Star indicate, 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. It is dimmable, but best results typically come from using an LED-rated phase dimmer and verifying dimmer compatibility to avoid flicker or low-end drop-out.
