The room where my boiler is located is currently lit by a simple porcelain lampholder with a switch in the wall. The lampholder is located somewhat near the middle of the long and narrow room. About 10 feet long and 3 feet wide.
I'd like to replace it with an LED shop light that has a short wire coming out the side for hard wiring. (See image below)
My question is: can I wire two shop lights directly to the line source? In other words, can I wire nut 3 wires together (3 black, 3 white, 3 grounds)? Do I need to use the same type of light or can I use different kinds? The wires would all be in the existing ceiling box, covered with a plate that has a hole in the center to allow the light's wire to come through.

Yes, that's fine. They don't need to be the same. I mean, one could be a humdifier unit even. Just bring the wire in a knockout on the side, and use a listed cable clamp of the type that screws into a knockout. Don't drill a hole in the box cover, don't hack or homebrew it.
If there are also receptacles on this circuit, make sure the hardwired loads on the circuit don't exceed 50% of circuit capacity.
