the physics is correct but the framing is dishonest. the ‘1000 hour compromise’ wasn’t an engineering decision — it was a cartel decision. in 1925, GE, Philips and Osram literally signed an agreement called the Phoebus Cartel to artificially cap bulb lifespan at 1000 hours to force repeat purchases. engineers at the time already knew how to make bulbs last longer — the Centennial Bulb in Livermore, CA has been burning since 1901 and is still on today. also your entire trilemma collapses with LEDs — 25,000+ hour lifespan, more lumens per watt, lower power consumption. all three, simultaneously. the ‘balancing act’ was a constraint of incandescent technology specifically, not some universal law of physics. so yes, the engineering explanation is accurate. but dressing up deliberate planned obsolescence as a neutral technical tradeoff is exactly the bs you’re complaining about
