You have a lot of options depending on budget and preferences. I would actually consider watching the BRS 52 weeks of reefing on YouTube, I think they have a few episodes there where they look at LEDs, T5s and metal halides. I know they are a business and in business to sell products but I think they do a great job with giving some solid info.
thanks, I did watch it. Was wondering if anyone with this style tank would have any experience on success with what lights. I know many work, gonna go with something with an arm mount. 3 wide should suffice.
Bowfronts can be a little funny to light. They are narrow on the ends and then wider in the middle, obviously. A real nice LED unit out there right now is the Reefi Duo Extreme. Its sharp looking, powerful, has all the features you could ask for and a few of them would look great over a 180.
