Circadian Optics

What Circadian Optics makes

Circadian Optics sells only bright light therapy lamps. The company says it was founded in 2016 and began in a Minnesota office; its homepage says the lamps are designed in Minneapolis. The range is split into a Clinical line (Langham, Langley) and a cheaper Core line (Lampu, Lumos 2.0, Lattis, Lumine, Lora, Luxy).

Claims to check

The headline claim is “10,000 lux of light,” but the homepage does not state the distance or the test method behind it. That matters: a lamp can hit 10,000 lux at a few inches and far less at arm’s length. Until independent measurements are published, treat the number as a best case. Our guide to using a SAD lamp covers distance and timing, and the lux levels tool puts the numbers in context.

The site also notes the lamps were “As seen on Shark Tank” and claims 500,000+ users. Neither says anything about light output.

Warranty

Circadian Optics offers free replacement if a lamp stops working for any reason within 4 years of purchase. That is longer than most budget lamp brands. We did not find a stated returns window on the homepage. Compare models on our light therapy lamps page.
