My wife prefers conventional incandescent to full spectrum or even incandescent for her upstairs studio. The problem is that the wall lights are mounted at least 8-10 feet off the ground, so I have to lug a ladder up the spiral staircase at annoyingly frequent intervals to replace them. Due to the pandemic lockdown, she hasn't been gone long enough for me to replace the bulbs with long-lasting LEDs of the same spectrum. She claims she can tell the difference, but I'd like to see it. Either way, if you're looking for traditional, old-fashioned lightbulbs, this is it. And why is Revane asking about "transparency"?
