Not sure how you feel about pendent LED's. Some people like them others don't but I like them because they make it ease to get in and out of my tank. But regardless I have 2 kessils A350W and they are 93 watt. My corals love them. Another think to consider is I just had one burn out after 11 months and the customer service was amazing. They send you the replacement first and also pay for shipping. And they have a 2 year warranty. I've heard of AI's burning out and people fighting with their customer service. And they only have a year warranty. If I'm gonna pay $400 on an LED I like the idea of having good customer support. Here's what they look like over my tank. Oh and the new models A360W are controllable like the AI's.
