Thanks guys ,that did help to clear things up. I was worried that certain brands put safety guards on the bulbs,so that they would only work with their ballast, thats what this guy was telling me anyways. I did want to pay for a set up and find out that aquarium bulbs didn't work in it, and this guy wasn't the type that would take something back after he sold it, if you know what i mean. He runs his operation out of a shack that is out in the boon docks. Anyways i have another question for you. What is the difference between a M57 and a M137 and how do I go about specifing that to a light guy? Is that common light terminalogy or is that aquarium talk?
thanks again, Greg
