    I have 5 300 VA units, 2x cheap brand, 2x CyberPower, 1x Eaton.
    I think 2 of them don’t have a transformer.

    Does it matter? All have a 9 Ah 12 V battery.
    It will last few to 20 minutes maybe.
    No issues so far (battery capacity loss excluded).

    Recently, as someone recommends, all batteries are outside of UPS enclosure,
    lower temperature. Which could affect battery lifetime.

    More power, more money 👀

    If anything, LEDs having MUCH better lifespans than bulbs is saving people.

    There are 2 (4 if high beams are separated) incandescent light bulbs in a car without LEDs.
    There is at least 1 extra point of redundancy.
    Also car light bulbs are made to last longer in automotive environment.

    LEDs having better lifespan in a paper. But In real world your mileage may vary.

    I’m not against LEDs, but current execution is bad: too bright, too easy to blind other people.
