I bought a huge 10,000 lux lamp that was supposed to emit similar wavelengths to daylight because I found myself to be a bit sleepy during winters all day long. That one managed to "wake me up" and I ended up as productive as in summer. Some people also use it to alleviate their seasonal depression (never had that). I have it illuminating my workspace behind my back. I believe our eyes have some special "wake up" receptors that react to sunrise and this type of lamp seems to engage them.

Can you provide some details on that lamp, especially power consumption? It seems an interesting experiment that I would like to try.

  I have one of these, but honestly haven't used it enough to assess it. It seems well made and bright enough to make a difference without being intolerable. I think it draws 14 watts.

Interesting. Why behind rather than in front? And which type did you get?

  The light is very strong even while diffuse, having it behind my back doesn't hurt my eyes and the effect is same. It's a non-LED one, not sure what is inside but it initially took 10 minutes to light up fully (now it's instant, probably some firmware for initial burn-in). I'll have to find box somewhere to tell you exact type.

    Ah makes sense. Just checked mine and it's 3360 lux, so yours is 3x stronger. I checked daylight, sunlight is 100,000 lux, and shade on a day with clear sky is 20,000. Our indoor lighting is way off! https://en.m.wikipedia.org/wiki/Daylight https://en.m.wikipedia.org/wiki/Daylight https://www.amazon.ca/dp/B072Q42GXQ/ref=cm_sw_r_cp_api_i_.FlPDb460MRN2 https://www.amazon.ca/dp/B072Q42GXQ/ref=cm_sw_r_cp_api_i_.Fl...

      I use similar ones for cinematography. Never occurred to me to use them at home as well :D When I think about it now, studios have huge lights that take a bit to warm up but then it feels like daylight, maybe my 10k lux is a similar tech...

for anyone interested - HL-NHB285-NP08B is a 30k lumen light for 150 dollars. it's 5000 kelvin color temperature. i parked one over my home office desk. it's like being outside at the park feeding birds, but inside. says 92 dollars per year power consumption. i dont know the terms of that calculation tbf i know your unit of lux takes into account the distance over which the energy is dispersed and mine of lumens, does not edit: a friend asked how to wire it. this is probably illegal in your jurisdiction but you can just lop the ends of an extension cord off, and direct wire the copper ends in and plug it into a wall outlet. you dont even need to buy wire nuts or any other accessory, other than possibly a hook, to hang the hook mount that comes with this unit. it took me like 10 minutes. this is not advice, no warranty is implied by my comment, i disavow all your actions if you do this. someone please correct my post and i will edit mine.

  I looked up the CRI, and it's 80. That's fairly low, it has a different spectrum from daylight. It probably works fine for this purpose mind you. I like the idea of mounting it overhead and illuminating the whole room. https://images.homedepot-static.com/catalog/pdfImages/ee/ee840b91-5dc6-4c67-9472-804b40ccea0a.pdf https://images.homedepot-static.com/catalog/pdfImages/ee/ee8...
