so I turned on some lights.

    I was a bit chilly earlier, so I put the heating on. Only for half an hour though, I’m not made of money.

      Almost completely transitioned to LED at this point. Still have a handful of half-mirror incandescent bulbs. They probably have LED versions of those now, right?

          I have a handful of incandescent half mirror globe bulbs. I haven’t had to replace any do haven’t looked for LED versions

            I’m just asking because I’m LED only now, and sometimes the “framerate” irks me. So I’m interested in knowing if this is the case for the traditional lightbulbs too.

              Many lights flicker around mains frequency (can be half or double IIRC). Incadecent lights don’t respond very quickly and so the flickering is a lot less noticable.

              Cheap LED lights are mains powered and flicker similar to cheap fluorescent bulbs. With a good rectifier and transformer the flicker should be way above visible frequency. LED dimming on cheaper constructions works by phase cutting which creates an even harsher on/off cycle and doesn’t feel that great. I don’t know how to know it was produced well and “expensive” doesn’t do the trick it seems.

              Cheaper LED lights also don’t emit the full visible spectrum of light to produce white. The light itself looks correct but when it bounces off the wall (or other objects) the color of that object doesn’t look right. That’s why you may experience a tone shift when taking pictures under an LED light (ie: you could look more green).

              I don’t know how to buy this right but the color can be bettered by buying CR95 lamps or similar. This rating identifies the spectrum of color.

              For the flickering I don’t know of a rating but when you DIY led strips with a dimmer you can choose a good power source and a dimmer which acts at a high enough frequency such as 1khz to mitigate the flickering effect.
