wtb--48" se mh/vho combo fixture

[henrystyle]

Looking for a 48" se mh/vho fixture for my new tank....
Must be in excellent condition...

Found one. $100 clean. Anyone know about hamilton mh/vho fixtures?
The fixture didn't come with the ballast. There is a black ballast cord and a grey cord that looks like a computer connection cord. Anyone know what that grey cord is for?
Will post some pics later...
