Small space, dimmer will help alot, 5k good for veg, 3k better for flower, nice to have a switch.
Cheap lights generally come equipped with cheap led, PAR in itself is useful but does little to determine quality of that radiation. Reds are often the least efficient colors in cheapo lights. If I was doing it all over again I'd really do research and get a high cri rating with quality reds.
You will pay alot more for a quality 100w compared to 100w from the bargain bin off amazon. Difference to end result would probably be negligible bit you did ask for quality. High cri.is.where quality lies, cri is the lights ability to replicate sunlight, a light of 100cri would recreate sunlight 100% identical. Far as I know highest is 99 and tha costs a fortune.
