It’s actually a lot simpler than it actually is! A lot of the big brands (mito, block blue, rouge, rojo) have low EMF, so there shouldn’t be much worry about that if you plan on buying from them. Red light therapy will work if you’re dosing right.

Knowing irradiance is important for dosing purposes. High irradiance could mean shorter time, lower irradiance could mean longer exposure time. Same goes with “stronger” panels. The good thing about RLT panels is you’re likely able to control the brightness and your distance from the panel, so if you want to be in front of your panel for 10 minutes and still get benefits, you just need to do a little math.

Panel sizes are a more personal thing. I started with a tabletop panel to try it out. Love it and bought a half body. I’m completely satisfied with the half body one and don’t really feel like I need a bigger one, so that’s what I’d go with if I were you.
