I can attest to the accuracy of this suggestion. I have the 135w kit from HLG and it's crushing a 2x2 space with very little need for heat management.I would look at utilizing 2x2 or slightly more of your space and go with a 135w quantum board kit.
If your not comfortable putting a plug on it and poking a wire in a hole then growers lights will provide it fully assembled for $25
Low heat. Good results.
And yeah 200w of QB would beat 300w of vipar.
