Indeed. Believing this garbage is a real black mark on
The incandescent bulb is a balancing act between efficiency (from high temperature) and longevity. By standardizing on one temperature, they ensured not only that their bulbs wouldn't produce odd color casts, but also no surprises on the electric bill, or surprise blown fuses, or surprise house/workshop fires while trying to get enough lumens for good illumination.
'Techies' have a very tenuous grasp of physics these days.
