The floros have always worked well in producing healthy plants but so will that 40w led. Hang it high. That spectrum produces great seedlings & clones. I did it with the HomeDepot Feit clone lights. Same spectrum almost. Key is low to no ir for maximum roots. And if its only one bulb then the footprint varies in output meaning you'd have to move things around daily. Unless it covers your setup well.
This one i put x3 together with the adjustable spectrum in the middle. Some of the fastest cloning results I've ever had.
Bad pic of clones though. Took them a few days into flower. Wish I had last cloning runs pics still.
