Hey Ying they are the same as the VHO's I have two 36" on my tank and there are the same color but look alittle bit brigther then when I had the VHO's.
Do they really suck up less power though? I have 2x110 46.5 inch VHOs right now. Can i get away with just 2x54 watt t5s instead? Sorry for hijacking ur thread steve
