Halo photo

Versatile light therapy lamp with sublime light quality for your wellbeing am-to-pm, all year round. Simulates sunlight to help relieve the symptoms of winter blues.

Sunlight is a natural mood-booster, influencing body chemistry (e.g. melatonin and serotonin levels), making you feel more awake and positive. If you are indoors, a bright light therapy session with Halo is the next best thing, putting you in a better mood, boosting energy and making you feel alert.

Utilising both warm-white and cool-white LEDs, this powerful light therapy lamp delivers 10,000 lux at 20cm at maximum brightness in Day Mode. The touch slider allows you to adjust the brightness while mixing the colour temperature of the light.

In Day Mode, Halo helps boost your mood, productivity and energy

So that you can work. So that you can play. Create. Design. Write. Code. Look good on a video conference call. Additionally, Halo's brightest setting helps treat the symptoms of SAD and winter blues in as little as 30 minutes a day.
