So, looking for opinions. I've got Icecap 660 ballast with (3) 46.5 VHO lights currently. Ready to order pack of (6) bulbs, but wondering if I should take this opportunity to cheaply and easily upgrade to T5. I've not read anything about T5's, but I've noticed VHO's are pretty much old school now.
So the question is:
1. Stick with (3) VHO lights
2. Change to (4) T5 48" bulbs and wire up into existing Icecap ballast.
