How can we help?

It gives you bright, daylight-style light indoors. Many people use one on dark winter mornings to feel more awake and keep a regular daily routine when there's less natural daylight.

Our lamps are bright everyday lighting products. They aren't medical devices and aren't intended to diagnose, treat or cure any condition.

Most people switch it on in the morning, for example during breakfast or while working at a desk. A common routine is around 30 minutes at 10,000 lux.

Brightness is highest close to the lamp, so follow the distance in your lamp's user manual. Start with shorter sessions and see what feels comfortable.

No. Our light therapy lamps use UV-free LEDs.

Lux measures how bright the light is where it lands. 10,000 lux is the brightness most light therapy lamps are rated at, measured close to the lamp.

Color temperature, in kelvin (K), describes the tone of the light: around 1600K to 3000K is warm amber, and 6000K to 6500K is cool daylight white.

If you have an eye condition, are sensitive to light, or take medication that increases light sensitivity, check with your doctor before using a bright light lamp.

Yes. Our desk lamps use flicker-free LEDs without ultraviolet or infrared light, with dimmable brightness so you can set a comfortable level.

Our desk and floor lamps plug into a standard household outlet and don't use batteries.
