My first workbench used an incandescent bulb that turned-on quickly, but gave off minimal light. At 150watts, it was a nice feature on cold nights.
Switched to a dual-24" fluorescent tube light; much brighter. These were a bit annoying because it often took my workshop lights several retries to light-up. One starter was argon, the other neon. It was always a contest to see how many restarts were needed as they clicked-away.
Then came the electronic ballasts, and no more startup flicker and basically instant-on.
Now I have a repurposed dual-element LED floodlight, which is so bright it will hurt your eyes to look at it and consumes even less power.
....BUT......the LED driver module has a startup delay of almost 2 seconds, kinda like the fluorescent fixture from long ago.
No worries, though. The LED lamp will still be going strong years after I'm gone. And yes, that is a ridiculously-overdesigned light switch, complete with voltmeters for each LED.
