What sort of outside lights would you call this? (feddit.uk)

I'm replacing the light at my front door, and I dont seem to be able to find what I want.

My current light is solar powered, light and motion sensitive so it only comes on at night and dims when there is no movement. However during winter there isn't enough light during the day to charge it so that it lasts longer than a couple of hours.

I would like to replace it with a mains powered one, but keeping the only on at night, and dims when there is no movement so that it illuminates the house number. Everything I see appears to only have one or the other (unless they actually have both but the listing details are terrible), does anyone know the terminology I need to use?

If you trust your wiring skills you could theoretically just alter it to have a low-amp constant power source then higher-amp power source by adding the signals when the sensor trips... I think the issue is a lot to do with the fact LEDs are way less dimmable than older lights though, as dimmer switches cut off parts to the waveform so have lower rms voltage and flicker, whereas you'd want to supply the same voltage, just fewer amps... if you're keeping it constant I think it's very possible?
