At first I thought you meant the ballasts. I was going to type in this whole thing about how you save a few bucks by going to an electrical wholesaler and looking up part#'s off the Advance Transformer website and blah blah blah.
But lamps? Oh ... yeah, OK, that's different.
Hate to say it but the local supply for lamps is ... well .. In 10 years with halides over tanks now I have yet to buy any lamps locally.
Not really a slight against the local stores, but it's just that the bigger mail-order vendors are in a better position to stockhold larger supply and more models and do it cost-effectively.
Thing to do there is go to a page like J&L, or OA, or premiumaquatics, find the bulb you want to go with (look at a couple different options), these places will tell you what ballast you need to run the lamps best on the info pages.
Anyhow there's my $0.02. Guess I just broke my own rule about cross-chatter in the buy/sell forum.
Please don't report me
