That's a good price if it comes with a bulb... They do get warm since the ballast is attached. I run two of them side by side. They work fine. It will rock an autoflower in a small space. I usually dedicate one 150 per plant. Just make sure to replace the bulb every grow to keep the lumens up.
Sunny you only do one per light? Is that because you run autos and can't top or train them? I ask because I run 4 in a perpetual garden. Photos only and I top and LST them. I pull 1 1/2-2oz every 2 weeks. I also have plenty of side lighting and I believe it is key with a 150hps. Here is a shot of my whole garden with the light raised and some lights off for the pic.
Another thing is it does not have deep penetration (the way your mom likes it!
) so you've got to keep it pretty close.
I've also done just one big plant that I topped , supercroped, and LST'd and it yeilded 4 1/4 oz here are some pics of that one.

I prefer to do 4 so I can get some verity.
