Is a PSMH light/12500 lumens ok to use

Is a PSMH light/12500 lumens ok to use?
1-2 plants

Is that like a 150 watt light?

yes it says it is a 150w But it is also a metal halide light that produces 12500 lumens

Metal halide is just the type of light it is. It’s pretty common for growing, mostly in vegetative period. But 150 watt isn’t very big, like for something around 2’x2’ space.

My grow tent is only 16x16x48

That should be alright then if you can keep cool enough. Is it capable of running hps bulb as well?

I just found for sale. A Mars1000w led full spectrum
