Using Vitamin L

Bright light is proven to put you in a better mood, boost energy and help you to feel more alert. It’s also proven to be an effective way to treat the symptoms of winter blues.

Slim and lightweight, use Vitamin L at home or take it with you to improve well-being at work or when studying. Light therapy is easy to fit in while you get on with something else.

Vitamin L can be positioned portrait or landscape – you don’t need to stare at it – when you’re at the computer, having breakfast, reading, watching TV etc.


Lumie Vitamin L is a slim, versatile energy light you can take with you. Sunlight is a natural mood-booster, influencing body chemistry (e.g. melatonin and serotonin levels) making us feel awake and positive. If you’re indoors, a dose of bright light is the next best thing and is proven to put you in a better mood, boost energy and help you to feel more alert – so it’s a great way to improve your well-being at work or at home, particularly in the darker winter months.

Vitamin L provides 10,000 lux at 6.3 inches so start off with 30 minutes a day and, if you need to, increase exposure until you find a treatment time that works for you. If you prefer it further away you’ll need to use it for longer.  You can get your daily dose of Vitamin L all in one go or have several short sessions for a cumulative effect. You should notice a real difference after just a few days.
