Help me choose spectrum please

I dont understand the whole spectrum, if , ans reds and stufd.....
Ill just post a few pictures of what im looking at could you help me choose and why....
Im trying to get 301h diodes, they have them but also have 301b diodes and other things so please just explain what im doing lol

O

H and B are the same. 3000k is good for veg and flowering

One more theres this one, also would it be wise to get a one knob does all dimmer switch or have 4 seperate knobs..also what is more efficient? Just a normal 3k spectrum or do i need all this uv amd all these other sprectrums

Do i need one with all these other spectrums or should i just go for white and red + ir?

Somebody else will answer that part better than I can. I've just gotten around to adding reds to my setup

Okay, one thing im curious about is, ive found ones that have a driver seperate and ones that have it built in....the one i was looking at has 8 single driver built in which i would assume is going to be hot?? Whats your thoughts on this

most of those lights have 660nm red leds already' adding UVA and violet light will improve taste and potency but you can groq without them.HPS has almost no vtolet or UV but still grew well

I think the general consensus is that less drivers are more efficient

my 2c:

3500k 90cri
or 3000k/3500k/4000k + 660nm

In my opinion 3500k is best all around. Add 660 Nan reds and you're golden. External drivers are more efficient and they can be remotely mounted to avoid heat issues. Currently run 800W actual Cree COBS at 3500K. Just ordered v3lm301h's with 660 at 3500k. I compared the two and the quantum boards are better.
