These are great value LED gooseneck lamps. We use them for our Avolites lighting desks, which requires a small amount of soldering at the XLR end to get the 12V on the correct pins (Avolites are Pin 1 = +12V, Pin 2 = 0V).
The lamp dims nicely when required, and has sufficient light output for most consoles.
The only negative is that the 'beam' is very narrow, so you won't get the same spread of light that you would from a traditional incandescent gooseneck lamp.
