Two of my adult daughters and I suffer from SAD and we do not look forward to winter. We live in the western United States, in the Rockie Mountains, in a valley that gets socked in by not only clouds but also fog, haze, and temperature inversions that keep air pollutants from exiting the valley. We can go for weeks without seeing the sun directly. Your design is simple, elegant, and effective.<br /><br />A word about the critics and detractors: all the buzz on various sites, such as Instructables and Reddit, about lux vs. lumen, blue light vs full spectrum, and on and on. Since this is a DIY medical device, makers of this project need to accept responsibility and figure out these things for themselves. If they're are concerned about these things they can figure out which bulbs are the safest for them. There seems to be ongoing research into how and why light therapy works with much of the older literature being confounded by newer findings. The beauty of your design is that the user can adapt the light bulbs/tubes/LEDs/etc to take advantage of the new information and technology.

Total less than $50. Instead of building a box, I just hang the cord with all the bulbs from a screw in the wall.Anonymoushttps://www.blogger.com/profile/03121549025271784371noreply@blogger.comtag:blogger.com,1999:blog-2961838602080369632.post-7640418171786934732011-11-15T17:01:06.072+01:002011-11-15T17:01:06.072+01:00Can you please give me the measurements of the box...Can you please give me the measurements of the box from Ikea, seems that it is discounted and I am trying to find one like it?

But, he adds, he's been lucky so far and he's 58. Two tricks to staying lucky, he says, are never doing anything significant enough to attract attention, and always interpreting your data to support your grantee's favorite theories. (He also says: "The perception that wisdom increases with age is a by-product of the high correlation between cynicism and reality.")Ray Heinrichhttps://www.blogger.com/profile/12358617353307542547noreply@blogger.comtag:blogger.com,1999:blog-2961838602080369632.post-68767112225502177762010-11-15T09:55:45.300+01:002010-11-15T09:55:45.300+01:00Thanks - it certainly is rewarding, but I think th...Thanks - it certainly is rewarding, but I think the ruthfulness of academic life is a bit overstated - or I have been lucky so far.Boris Legradichttps://www.blogger.com/profile/06306946018677419450noreply@blogger.comtag:blogger.com,1999:blog-2961838602080369632.post-46375807525135946702010-11-13T00:24:21.910+01:002010-11-13T00:24:21.910+01:00plasma, cool! good luck on the science deal. i hea...plasma, cool! good luck on the science deal. i hear it's ruthless and rewarding... and wow, those sockets with plugs, have used before but for some reason never thought of plug strips to make light bars!! great idea!Ray Heinrichhttps://www.blogger.com/profile/12358617353307542547noreply@blogger.comtag:blogger.com,1999:blog-2961838602080369632.post-44416549847893948072010-11-11T14:05:50.995+01:002010-11-11T14:05:50.995+01:00Thanks for letting me know about your build!

I had a small Phillips unit that I bought at Costco but after a few years in stopped working and this is why I searched out how to build my own. The Costco unit cost around $150 and used blue LED lights and it helped. <br />I have modified your build to prevent myself from having to any wiring and while it is not as pretty as yours it still worked. I found light sockets that plug into wall sockets and bought 4 cheap power bars so I could mount these and the sockets into a box and put one more power bar on the back of the box to plug the other power bars into so I could have one wall plug. My unit has 12 of the 23W =100w bulbs and holy cow is it bright. I put the rather large unit on my desk and sit and listen to podcasts for approx. 30 min. and it feels like I have had a walk in the sun which is an amazing feeling. I remember at some point doing some research and finding that not only is the lux important but they also stressed the time of day you use it is also crucial on your condition. If you have insomnia and wake up at a given time many mornings there is a specific time of day and length of time you should use the light. I find mornings are great to get me going but there is also other factors when you should use the light. <br /><br />The question of where the light should be has been brought up and Phillips recommends it be in your peripheral vision and not to look directly at the light.<br /><br />All the best,<br /><br />Cliff<br /><br />http://www.p4c.philips.com/cgi-bin/dcbint/faqview?view=aa12_view_full.html&dct=QAD&refnr=0074796&slg=ENG&scy=GB&ctn=HF3330/01Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2961838602080369632.post-42256396429538147662010-05-11T10:03:07.482+01:002010-05-11T10:03:07.482+01:00Nice 3d model, and a very good idea with the light...Nice 3d model, and a very good idea with the light-strip.

That's really good to know. <BR/><BR/>Because I'm really lazy and don't care how stuff looks, <BR/>I made some quick and dirty light "boxes" that seem to<BR/>work just fine: <BR/><BR/>1. First version: I bought four clamp lights with reflectors<BR/>and four twin socket adapters ($43 including shipping<BR/>from Hardware World, etc.) and put 8 23 watt flourescent bulbs<BR/>in them. I clamped these to a bookshelf and just plugged<BR/>them into a power strip I had around. (8 x 23 watts<BR/>is 184 watts, power strip will take 1800 so no big deal). <BR/>Kinda big and clunky but zero work.<BR/><BR/>2. Wanted bigger and better so I bought two 6-light vanity <BR/>(bath, etc.) bar light fixtures at Home Depot for $14.95 <BR/>each and used wire nuts to hook them to two regular extension <BR/>cords. (12 x 23 watts is 276 watts. My computer + monitor <BR/>takes over 400, so no big deal.) and placed them pointing out <BR/>on same bookshelf just above and behind my computer monitor.<BR/>Bookshelf top and bottom are white so I think this works ok. <BR/>My face is about 2 1/2 feet from bulbs and I can work at <BR/>computer for 1/2 hour with them on without very much terminal<BR/>eye strain.<BR/><BR/>And yes, after about two weeks I really noticed a difference.<BR/>It could be just me thinking it does (placebo) but hey, that's<BR/>ok too. - RayAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2961838602080369632.post-72183484410124682252009-01-12T10:42:00.000+01:002009-01-12T10:42:00.000+01:00Well, I could have done that, but then I would not...Well, I could have done that, but then I would not have known that two 2100 Lumen bulbs are much too dim to have much of an effect.
