Actually it's here, and has been for a while, as far as ballast and endcaps. I still like the VHO better on my 29g so I went back to it. I have pics comparing the 2(look back 1 page in this forum). Workhorse ballasts support T5 lights, and there are now a couple places in the states that sell the bulbs. Best advantage, they are pretty cheap. I might giv them a try again over my 90g.
