#sad #verilux Verilux is the market leader for SAD therapy lights. As a lighting researcher, I question some of their marketing claims, especially the claim that their lights provide "10,000 lux" of illumination.

Sleep medicine doc here. A lot of our colleagues had no idea what on earth 10000 lux meant and just recommended it for people for insomnia. This video is great! I have a lamp myself but I was aware that I was not getting 10000 lux. I figured that was just an insane number. I also have luminette glasses which I think are pretty effective.

@GregYeutter Год назад

Really appreciate your input on this. We are working on a product that is going to make the 10,000 lux claim completely obsolete and give people more balanced, low-glare illumination that still supports circadian stimulus. If you're interested, please sign up for the newsletter at bedtimebulb.com or drop us a line at hey [at] bedtimebulb [dot] com.

I've been watching a bunch of generic stuff from psychiatrists about light therapy but this was what I was looking for. The light box I purchased (prior to watching this) does have a 6500k LED so that's good. Vertical placement makes sense since the sun shines down into your eyes at an angle. I think I'll be leaving my light on for a longer time at a lower intensity. Thanks for the great info.

@sandercohen3309 3 года назад

Since you have a Spectrophotometer, it would be really cool if you could measure the Lux of the Elgato Key Light at various distances. It's an extremely popular light that claims to be offering 2800 lumens, but it doesn't say how many Lux (and at what distances) That's because it's not meant specifically for light therapy, but for video production and streaming. But it looks really bright, so I'm wondering if it can be dual purpose (used for both video production and light therapy)

@sandercohen3309 3 года назад

The Elgato Key Light can also be mounted on the desk (so about 24 inches away from you) and angled, for optimal melanopic efficiency. So it would be really cool if a light nerd such as yourself would do some measurements on this thing. I'm thinking about getting two of them and mounting one of the right side and one of the left side of my desk.

I have recently moved to a location by the Arctic circle and I have been considering getting one of these SAD lights, as we will soon go into total darkness out here. I have been doing lots of research and reading up on these lamps and honestly haven’t been totally convinced… This video has been by far the most comprehensive source of information. Personally, I have been looking at Beurer, which has been celebrated for its German engineering and also as it has been certified/approved as medical equipment. Would love to get you test one of their products. However after watching this video, I think that even my Newer stand lamp might be a good source of light for the circadian rhythm.
