Jesco Lighting

You’re selling a shelve? How nice! Funny how the plural of “shelve” is “shelfs”. English, what a language!

Do the lights in these tilt/swivel at all?

Can the 2 or 3 light linkables be hard wired for over a kitchen sink light? How bright are these ?

Not quite correct…
It is ‘a shelf’, the plural being ‘shelves’.
‘Shelve’ means to put something on a shelf… or to cancel/postpone something.

Can more than 3 of the puck lights be linked together or will I have to plug in each set of 3?

OK, you win, pedantry is superior to humor when dealing with trivial matters.
