Yes, a 315 cmh,3100k is more than enough for that size tent. Not sure of quality of light in link. I run over priced Sun system 315 cmh

The 315w is more than enough for that space. For a single light and mainly autos I'd recommend you go with the 4200k bulb for a single light right through the cycle.

However, look for a vented hood, you'll need it to manage heat in a 5ft. space. The other potential issue in a 60" height is you need about 20" above canopy, then 14-16" for the hood, which leaves you somewhere around 2ft. maximum height plants.

imo you'd be better off with LED COBs in there, lots of lights out there using Citizen or Vero COBs at reasonable prices. 200-250w of proper 4000k COBs would do great in that space.

I use both so not tied into one tech or another other than using the proper tech in the proper space. In this case LED's would be super easy to manage in that space while CMH would be a pain. Your environment is as important as the light tech.
