Is it correct to add Lumens for adjacent bulbs?
Would it be correct to say that three 330 bulbs arranged in triangular formation in one light fitting yield 990 Lumens?

I have osteoarthritis in my hands so I speak my messages into a microphone using Dragon. Some people make "typos" but I often make "speakos".

I think you may be correct is if they are physically next to each other, but it is like putting a 1k heater in each of three rooms, then saying you have a 3k heater.
Lux though would be different. For it to really add ups as lumen, all the light has to come from one source (or point)0 -

Thank you, bluesnake, that's about what I presumed. Regards, Sterling.I have osteoarthritis in my hands so I speak my messages into a microphone using Dragon. Some people make "typos" but I often make "speakos".0 -
Yes, you can add them together. But one 660Lm bulb will be more efficient than 2 330Lm ones.0
