Let's say I'm growing in a smallish cabinet and have 2' by 2' of usable space.
Do I buy the light specified for that exact area by the seller or is it worthwhile to go a bit bigger to get more light into that same space?
Or is it completely wasted because the bigger light will shine on the walls and contribute nothing useful to the plants inside the 2' by 2' area?
(The lenses in the new LED fixtures complicate things as they seem to be focused on a particular distance and area)
