Shop Lighting advice wanted/helps with my employment. 3 bay layout, with GIANT I beams coming down lower than lights mounting location

My shop is 22x80, not quite as large, but also has 13-15' ceilings.

I started buying Rural King store brand 4' LED shop lights a few at a time, when they were on sale back when the design spec was 4500 lumens.

I intended to hang up to 4 or 6 in each 20x22 bay. I only got around to hanging 2 per bay, as long as the supplied chain down from the 2nd highest roof beam, and about 2/3 distance into the shop (about where the engine compartment ends up. They worked so well, I haven't felt the need to buy and hang any more. I did save one out and installed hooks to make it an underhood light if needed.

That same basic light is now 6000 lumens.

Previously, there had been a single 100 watt incandescent per bay. I simply removed that medium base fixture and swapped in a recep for the shop lights. The difference between the 100 watt and the two 4500 lumen LEDs was staggering.

For residential, in FL you can use 14 gauge wire and 15 amp breakers for lighting.
It's been a while since I've referenced codes, but I think commercial requires 12 and 20 amp, and it has to be in conduit.
Of course those 2 LEDS don't draw nearly what the 100w incandescent did.
