If the lights you bought are 55 watts x 2 and you have a 37 gallon tank, I would say that those lights are not sufficient for most corals and especially not anemones. That equals out to less than 3 watts per gallon, which is really not enough light for much, except low light corals such as mushrooms, xenia and kenya trees. Most corals need at least 5 watts per gallon, and anemones need even more light, at least 8 watts per gallon. Now that's not a hard and fast rule or anything, but if I were you I'd really return those lights and get something stronger. If you are planning on keeping corals and anemones, those lights won't be sufficient. If you want to start with a few low light corals and then upgrade lights later on, that'd also work.
