I agree that we should be very carufull. I was under impression that it's safer to use C.V. driver.
now I'm not sure again wich one to use

to many options in DIY LED
I went CV route for the exact same reason. I don't regret doing it, but I wonder just how less dangerous 7A @ 20V are compared to 0.7A @ 200V.
The water analogy for electricity (which seems to be the most popular on internet) states that if voltage is low enough, then there is not enough "pressure" (difference in potentials) to "push" the current through your body. But I don't know if 20V is low enough or not
Regardless, I have my AC side completely sealed (schuko plugs in sockets, no exposed wires anywhere), and for my DC side I did the best I could (no exposed wires; insulation runs into wagos, connectors on strips; taped over solder pads on strips with insulation tape). But on DC side there will be higher humidity, less room for manipulating things, etc.
I really hope this will be enough, since I plan to have my light as close to the plants as possible (
inverse-square law thingy and
light intensity) and with little room between plant and light one could easily touch something one might regret...
