Two Vion Z6 10000K 175 watt metal halide bulbs for sale. Used from June 1st through August 16, approx. 5 hours a day. Like new condition. $100.00 for the pair, firm.
I think they are in the yellow/white part of the spectrum. I just replaced these two with new Ushio 10000K bulbs and they are about as crisp white as you can get. The Ushios also appear to be brighter, even running off the same ballast as the Vions.
If someone has a calcium reactor that they would like to part with I would be willing to trade the bulbs and some cash to square up the deal. Any takers?
