Hlg 350r or hlg 300l rspec

Which of these two lights would work best for a closet. I grow a single plant at a time, and the closet is 4’ x 2 1/2’ x 8’ high. I’m using a cmh 315 right now, and looking for some denser buds.

Having used R-Spec boards myself, if I was buying new I would go with the HLG 350R you have 10 sq.ft. of space giving you 30w+ per. Better efficiency, more total PPF, better spread from the larger fixture. Only $100 more.

I was using phantom 315cmh, I switched to this:

and this:

They will replace 2 315cmh that were 30" apart bulb to bulb.
I reduced watts by 50% results are a little better yield.
I like the Hortilux because of the UV, I was using the Hortilux bulbs which had UV in the 315.
