Backing plate on flourescent light?

Yes I did a search and yes I know there are 30849038409 threads on garage lighting but....



I am not asking you what lights I need or what you have. I just want to know if the backing plate is important or not...



Went to home depot today to research me some 4' flourescent shop lights. They have 2 different ones I like but I need some help on picking which one. One is $16 looks perfect but it doesnt really have a curved backing plate to I guess reflect the light downward. The bulbs are more or less just exposed if you know what I mean. The second one is $36 has a pull cord looks a little bit nicer and has a big backing plate that would reflect the light down...





My question is do I need to fork out the dough for the one thats twice as much cause of the backing plate or not?





My garage is 11'x20' and I will have 4 of these 4' flourescent lights hanging. Two will be in a row on one side and the other two in a row on the other side...





Thank you



Oh and the cheaper one can use T12's and T8's the expensive one only takes T8's. I plan on using T8 natural light flourescent bulbs but they do have some T8 daylight delux bulbs that I am trying to figure out the diff. I still dont know what the color temp numbers mean yet or the light output numbers mean as in high is better or low is better....



EDIT: Figured out What light output (lumens) CRI (color rendering index) and Color temp are...



Thanks again lol
 
what color is the ceiling? is is finished or open joists?

how far below it are they hung? or surface mounted?



if hung or not finished/painted white, I'd spring for the reflectors...
