Yo yo, 2 words of caution. Don't say someone didn't warn you. That 15'' sound activated 'light' has a great tendancy to burn out extremely fast. Infact what happens more often as well is if it is used vertically.. while in sound mode half of the tube will completely stop working. Very common issue i've heard it over and over. But not really a big loss if it does happen.
Warning two is if youre trying to illuminate your case with blacklight, your white light will indeed drown it out.
BUT, most important.. that model 15'' has an EXTREMELY short cord from the mount to the p/s. Everyone seems to hate that.. can't imagine why.
