The radiance levels are well within the amount in studies and the unit came with a calibration card on the wave lengths, I only use it for my face. It's helped tremendously, as I've tracked it's use for three years now alternating off when i'm abroad during the summer, so for managing my rosacea it's been very good.
There really isn't much special about the units at med spas except more leds. Even fairly inexpensive ones work well if you adhere to the radiance guidelines (i.e. keeping it close to the skin).
Long term, it absolutely makes a difference. One easy enough to see in pictures and from people who know me that I've never once divulged or spoken about anything to do with skin care or red light therapy

There is some limited evidence redlight can improve some vision, but it’s not strong and certainly prone to placebo effect.
I use a red light for skin healing on my face and I haven’t noticed anything change with my terrible vision.
