I have some old incandescent R80 downlights in my kitchen. I'd like to replace them with LEDs. Are there LEDs that work off 240 volts without a transformer/driver so that I can simply disconnect the old fitting and replace it with the new one? This is the easiest option for me because I believe I can get LEDs which fit the existing R80 cut out? I'm also looking for a bathroom equivalent with a rating of IP65
