I wanna get some lights like these.

Question

  How easy would it be to attach some lights like these to the back of some speakers? I'm moving my decks to its own table and I will have speakers either side of my laptop that will be in the centre.I want the lights to attach to the back of the speakers and glow against my wall to give off an aura.  Also will prolonged use tint the paint on the wall?

Answer 1

Well as Pat states the affect will usually only work as seen here if the wall is able to reflect the maximum amount of emitted light.
LED tubes are good for this effect because the light they give off is of a high intensity but it doesn't travel far, hence the darkness being preserved away from source. Although this picture is obviously edited to exaggerate the contrast, a big screen TV like shown in that picture also helps because the light from that will drown out the light that leaks on to the walls the further away from the source. Think of a gas lighter beside a cars headlights, you won't see the flame from the gas lighter. Turn that TV off and the purple will appear to extend further up the walls.
It isn't particularly difficult to do, but you will probably go through some trial and error. And think about what colour light you will use... do you really want a purple wall?
