Just fitted these the other day from
www.glowpatch.com and thought some of your might be interested.
Great for a bedroom and compared to fibre optic panels a lot more reasonable in cost. (Less work)
Just stick em on, took about 2 hrs for 800ish stars. Really looks good.
I put them into my home theatre, but they are better suited to a bedroom as the tv drowns them out. With all light off they really do look good.
I have the ceiling painted black and I think this helps too.
(I have no affiliation with glow patch,)
I bought the medium pack for $146 and it' had plenty for a 4x3.5m room.
