I see many downlights have a normal 3 prong plug on them. My understanding is this makes it easier to install new lights (plug and play) and don;t need an electrician. However, how common are they - I notice plenty for sale that are wired in without a plug. I'm looking to standardise mine at home (got a mix of 3 different kids, including halogen), and suspect it might be best to have the electrician add plugs instead of hard-wiring.
Also, if I go plug-in, are there any recommended brands/types? I've got quite a few Hue lights, but not sure if the downlights are a good idea.
I switched a bunch of my downlights to plugs a while back, when switching from halogens. was about $15 per light i think? maybe less. Cant see any reason not to, given that it means i can now change them to my hearts content
