The issue I have with this is there isn't a consensus about what and if any of these products work. The IES (illumination engineering society) has released a couple articles about why consumers should be weary of products that claim to control the rythms and after attending a talk from the IES on the subject I'm not convinced any of it works (at least to the degree marketing says it does)
