Both give a very intense light, adequate for the most Sun-living CP.
But HID lights generate a large amount of heat which must be dissipated. They also cost more to operate, using more electricity to generate the same amount of light.
LED lights give me intense Red coloration on my CP, particularly Drosera. They color up my typical Cephalotus to a Purple so dark, it is almost black.
I've tried HID high pressures sodium and metal halide lighting. I tried T12, T8, and T5 fluorescents. I gave away the HID stuff and switched to all LED lighting.
My two main lights are MarsHydro 300s. I also have some T8 daylight LED replacement tubes that fit fluorescent fixtures. I even have a couple of 100W equivalent LED screw-in daylight lightbulbs.
Every grow setup is different. But for me, LED lighting was the best choice.
This is one grower's opinion.
Good growing,
