I have a Sunpod, and while I like it, it is a bit limiting --- just the MH, no additional bulbs.
I have 2 Fiji Purples over my 75 (( part of my Outer Orbit fixture )), and think they are great bulbs -- so I would try at least one of those bulbs in your fixture. Think you would be happier trying new bulbs first, as opposed to getting the Sunpod.
