Yay!
It's from Rasha, model RD-F015. 500mW RGB.
I had to take the face off to rescue a loose nut, so I snapped a couple of photos.
(There's no warranty stickers [good thing or bad?] so if anyone wants I can take the thing to bits and get some better shots)
Photos of it in action pending (as soon as I get home :-D)
