## Description

Product Description Lumie Vitamin L is a slim, versatile energy light you can use anywhere. 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. It can also be an effective treatment for SAD (Seasonal Affective Disorder). Vitamin L SAD light was created by Lumie, the Cambridge-based light therapy specialist and inventor of the first wake-up lights. Vitamin L is not a vitamin, but a reference to the mood-enhancing properties of light. Box Contains Lumie Vitamin L SAD and energy lamp Mains power adaptor User guide

Review: Brilliant - Brilliant SAD lamp. Holy moly this thing is bright. It massively helped me during the winter and is super easy to use. It’s too bright to have facing you head on, but off to the side works really well. Keep mine on my filing cabinet, next to my desk, so I’ve got some light whilst working. Doesn’t take up a lot of room, very easy to assemble and operate. Looks very sleek.
Review: Powerful, significant and instant benefits - I don't have to tell a detailed story to explain to anyone in the UK the struggles of winter weather. Cold, grey and miserable despite my best attitude possible. I actually thought the benefits of this would be a placebo. Anyone who's familiar with the Only fools and horses episode when Del is selling the infrared massage gun, I had the same expectations... Glad to say I was totally wrong and I've been blown away for a number of reasons. Firstly it's well packaged and very well made and turned off it even looks good, it's very smart looking. Secondly it's VERY bright. You know, you almost expect when you buy a bright white bulb off desertcart to find it to be bright yet I was still surprised. I'd much rather it be bright than not bright enough so if you're worried it won't be powerful enough don't, Stevie Wonder would know when I turn it on. I'd say within 45 seconds and I adjusted to the intensity I felt 50% more awake and I knew why this made sense as a purchase. In the summer I go outside first thing and the sun wakes me up and I'm ready for the day, my Lumie light is just a replacement during the winter months. I had a significant and noticeable difference in how I felt. I found it best for a few hours in the morning before the dark grey sky turns a slightly lighter grey, off during the day when I'm awake and I turn it back on from 4pm onwards until about 8PM when I'd like to be tired. Overall it's very pleasant, takes 5 minutes to adjust and you can carry on with whatever you're doing feeling significantly more awake, alert and honestly, happier. I've gone into length here with the aim of helping someone else solve their own winter blues, trust me give it a go for a day or so you can always return it.

## Questions & Answers

**Q: How an anyone realistically have this lamp 20cm away from their face? Does it work a metre away for longer?**
A: I agree, unless you spent a lot of money you are supposed to sit 20cm from this or any other lamp - it's almost impossible. I believe there is an effect from up to 1 m away for longer periods. I bought the lamp because I didn't like the light from SADS lights when they are bright white. This lamp produces a very pleasant light and I try to spend as much time as close as I can to it.

**Q: Does this have a warranty?**
A: The seller says that this has a 3 year warranty, I have a lamp that has stopped working which I bought less than three years ago bit more than two. How do I go about getting help please?

**Q: Does it work for SAD?**
A: Totally! I’m Spanish in the U.K. for 20+ years, best winters since years ago I got this Lumie vitamin lamp. Can’t recommend it more!

**Q: How many watts does this consume?**
A: According to the Lumie website 108 watts (3 x 36w bulbs). Used for an hour a day that's about 3.3 units of electricity a month or about 50p

### ⭐⭐⭐⭐⭐ Shedding Some Light on Lumie Vitamin L: A Slim Solution for S.A.D Sufferers
*by S***Y on 26 March 2024*

I don't know about you, but I've always been a bit skeptical of products that claim to cure the winter blues. So when I heard about the Lumie Vitamin L Slim Light Box, I was more than a little dubious. I mean, how could a little box of light make me feel happier and more energized during the darkest months of the year? But let me tell you, this thing works! I started using the Lumie Vitamin L a few weeks ago, and I've already noticed a difference in my mood. I used to feel like a grumpy bear in hibernation during the winter months, but now I actually feel like a somewhat functioning member of society. It's like someone turned on a switch in my brain and suddenly I'm not as gloomy and lethargic as I used to be. The slim design of the Lumie Vitamin L is perfect for those of us with limited space. It fits easily on my desk or bedside table, and I can even take it with me when I travel. So now I can get my daily dose of light therapy no matter where I am. I even tried using it while watching TV, and let me tell you, it's a real game changer. Who knew that a little box of light could make Netflix and chilling even better? But my favorite thing about the Lumie Vitamin L is that it's so easy to use. There are no complicated settings or buttons to figure out. You just plug it in, press the power button, and bask in the glow of its warm light. It's like having a little slice of sunshine right in your own home. Of course, I do have a few minor complaints about the Lumie Vitamin L. For one, the light can be a bit intense if you're not used to it. I made the mistake of staring directly at it for too long and ended up with spots in front of my eyes. Lesson learned: don't stare into the light like you're auditioning for a role in a horror film. Overall, I would highly recommend the Lumie Vitamin L Slim Light Box to anyone suffering from the winter doldrums. It's a simple, effective, and oh-so-bright way to chase away the blues. Just don't forget to wear sunglasses if you decide to get up close and personal with it. Trust me, you'll thank me later.
