TL;DR

Allow Lamps to be made in Electromagnetic Plants.

What?

I suggest that the Lamp should be craftable by Electromagnetic Plants in addition to the character and in Assemblers. No removal of functionality, just addition.

Why?

It seems thematically appropriate. I was surprised when I first tried to do so but couldn't find the Lamp in the Electromagnetic Plant crafting menu. So much so that it took probably a half dozen more tries before I stopped expecting to see the Lamp there.

The Lamp (being a Final Product, not an Intermediate Product) does not qualify for Productivity Modules, so allowing it to be produced in the Electromagnetic Plant (which has a +50% Productivity Bonus) would lead to Balance issues.

There is of course a mod that does it anyway.

Good Luck!

Given that the lamp is extremely cheap, purely* cosmetic, and isn't used as an ingredient for anything, I fail to see how there is a balance issue here.

And the the Electromagnetic Plant already produces final products that do not qualify for productivity modules, such as beacons, modules, and electromagnetic plants.

*: Okay, I guess technically it could be used as a darkness detector through the electricity consumption when on vs off, so it does have noncosmetic use.

The Electromagnetic Plant has 5 Module Slots, allowing for a larger Quality Bonus (+31%) than the Assembling Machine 3 (+24.8%). Combined with the extra Productivity Bonus you could make a far more efficient Quality Recycling setup than normally possible.

Quality doesn't do anything for Lamps, and this is already possible with other products like the Beacon, so it isn't a real problem. I don't make the rules, just point to what already exists.

It's just fun and completely fine if there are randomly things that behave different in the game. Maybe this is one of them, maybe not. The lamp produces fine in assembling machines so make em there!

But you can make beacons, or other EM plant in the EM plant, both "final product" that normally do not qualify for productivity module. I don't see the balance issue there.

These are the reasons why this feature sounds pointless to me. Lamps aren’t upcycled for quality either, and aren’t mass produced nearly as much as belts and pipes. Making them in the EMP sounds like it would have 0 real benefit.

The feature has 0 downside , and would also apply nicely to combinators , for a thematic addition

The only reason for the suggestion is that I because of the theming and things already made in the EM plant, I was pretty certain that Lamps would be too and was surprised they are not. I presume I was not alone in this expectation, in which case this change would benefit the game by fixing this mismatch of expectations.

If I am essentially alone in this expectation, then of course, the suggestion shouldn't be implemented.

I would also find it "thematically" correct to make lamps in the EM plant , +1

It never occurred to me but yeah. +1 for theme
