I got some led shop lights off Amazon that are unbelievably lightweight and would be totally fine on command strips, if the command strips are stuck to non-textured clean surface.
They are 5000k leds. Here’s the link if you want more info.
Bbounder 4 Pack Linkable LED Utility Shop Light, 4 FT, 4000 LM, 48 Inch Integrated Fixture for Garage, 40W Equivalent 250W, 5000K Daylight, Surface + Suspension Mount, White https://www.amazon.com/dp/B0868DVRL7/ref=cm_sw_r_cp_api_glt_fabc_RQMH6F6DKV56FEZFEYK2?_encoding=UTF8&psc=1
I installed 6 of these https://smile.amazon.com/gp/product/B0868DVRL7/ lights in my 20x15 workshop (two rows of 3) and the the space is super bright. There are some minor shadows, but a lot of light bounces off the white ceiling and helps spread the light.
Here they are:

i bought these ones.. $60. They're only 40w each, I run them for about 10 hours a day, seven days a week, and have seen very minimal impact on my electricity bill. I installed them before winter, when our bill naturally runs a little higher, but in the late summer/fall months when I was running them I actually didn't see much of a difference at all. They also don't put off heat, which is nice. The color is a nice bright white. They're LED, so they'll last you forever.
You can mount them from the ceiling or the wall (I have mine wall-mounted on all four walls in my room). The other commenter is right, Amazon is undoubtedly unethical, and it's always best to try to find other businesses to support, but this is what I personally did.
Here's a picture of one of mine while it's off. Installation was super easy.
I have the same size shelf, my lights are on chains that I make shorter or longer as seedlings grow. It’s a lot easier than moving the shelf.
I’ve linked the ones I’ve used. I like them bc they’re lightweight, can link up with each other (I have multiple multiple shelves), and come with a chain (I use needle nose pliers to adjust the chain length). Two lights per shelf seem to do the trick. Lights
And if you don’t have a timer yet, I suggest using one, they’re super helpful. I use one like this.

It's a combination of these lights and some old fluorescent shop lights that I converted to LED.
How about something like these shop lights?
You can daisy chain them, so essentially 1 plug to the wall.
