A little over a year ago I purchased a couple of new Lumatek ballasts, Lumenarec Reflectors, bulbs and other odds and ends from Pacific Garden Supply (PGS), sure I could have gotten it elsewhere for a lower price, but I've always liked Tom and Dan and I've learned a ton about lighting from them, I thought it would be nice to return the favor and put my money where my mouth is. Yesterday I received my new Ushio 20k+ bulbs from another local business, coralreefecosystems.com, Steve is another stand up guy who you can trust to get good info from. Anyway, one of my ballasts will not fire either Ushio bulb, yet will fire any other bulb try. I placed a call to Dan at PGS this morning and much to my surprise he said, "lets just swap the ballast out", it's been over a year and it won't fire one silly little bulb yet he didn't even hesitate to do the swap, he even offered to ship a loaner down until I can get up there to do the exchange. Now I know why made the purchase that I did, in just about any other situation I'd be hosed. Thanks PGS!!!
