Lighting

Can someone recommend a good moon light for a 4ft tank. I had some R2 Extremes on my tank and the power adapter fell apart and cannot get in contact with them about a replacement.

I am in the process of building a canopy for my tank and wanted to know what the total length of a t5 with stand off will be for a 75gal rr tank. I am currently running a Icecap vho setup and want to change to t5. I am currently running a 46.5 inch setup on the vho's and total length fit in my temp canopy of 48 inches.

thanks
