This looks like something interesting to try out. Mainly because it seems pretty easy to set up. Will any bulb work? There are bulbs on amazon - but state they are used for aquariums or plant growing. They are 45 Watt 450 nm LED blue light bulbs. The bulb you listed from Philips didn't seem easy to get. I was going to try it 30 min 3 times a week as listed in the case study. I wonder if just lighting a part of the body instead of the whole body would have the same effect. Can I just target a limb? I also wonder how it affects the skin.
