All you need is the 460 nanometer wavelength of light. That's what your eye's daylight detectors are most sensitive to. Halogen lights don't have that frequency

All you need is the 460 nanometer wavelength of light. That's what your eye's daylight detectors are most sensitive to. Halogen lights don't have that frequency, which is why they didn't work for you.
Furthermore, you don't need this light all day. Just in the morning and evening.
You can get 460 nanometer LED lights from grow shops online for around $50, and put it close to your face for 15 minutes in the morning and evening. It'll reset your rhythm, cure your sad, and that's all you need.

- Sammi 11y agoFinally someone mentions this. Wikipedia has all the imformation on this: https://en.wikipedia.org/wiki/Intrinsically_photosensitive_retinal_ganglion_cells https://en.wikipedia.org/wiki/Intrinsically_photosensitive_r... It's because we have special photosensitive cells in the sides of our eyes that only see blue light. They're not part of the vision, they only regulate the circadian rhythm. So all this talk of white light is uninformed. You only need blue light.
