Sorry for the basic question I'm still getting my head around the basics of ELV, MLV etc. I have a light with the following help for dimmable lights. Because it says "Dimmable with mains voltage dimmer" I presume it can use a regular switch. But I'm not sure based on the rest of the spec. The full text is: ---------- Dimmable with mains voltage dimmer (dimmer for incandescent, halogen) Please make sure to use a dimmer rated for a low power luminaire. Input voltage of 110-127V~60Hz AC Voltage on lamp < 5V DC (actual lamp surface functions as conductor!) Then lower down it says this (but I'm not sure if this is only for the CE version): Transformer type: Electronic Low Voltage (ELV) Load type: Capacitive load (C-Type) Dimmer type: Trailing edge / Reverse phase, 1-10V dimmable (please make sure the right provisions are made for 0-10V/1-10V dimming) And the full spec is available here: https://www.moooi.com/node/104/pdf2 --------- Thanks for your help!
