Yea, they are neon, I just tossed in the sand and some DIY rocks I had made a year ago, so they have been outside soaking, ive got some more thats been in my sump for about 6 months and they are bleached out but are now bio rock, and should pick up and grow coraline quickly. The lights have a small ballast built inline in the cable, and for taking 12vt's the power consumption is nil I may just double them up if they are not enough, il get a pic as soon as the reef lights go out. A word of warning to anybody that might go pick some up and try this, read the package because one type and those are the longer ones, They are music activated and pulse outward from the center to the music
