Adding lights on the same circuit as garage door opener

I have a 20amp circuit that has 16 60 watt lights, 2 outlets (in bedroom), 1/2 hp garage door opener. I want to replace 1 of the 60 watt lights with 4 4’ 40 watt 2 bulb fixtures. I think I’m ok with the load but want to confirm I’m correct.

Update the fixtures I want to install are 40 watt T12 Fluorescent fixtures.
