Led lighting for a 180 gallon tank.

It doesnt say what the light actually runs for watts. 130 .5 leds would be 65w max but likely closer to 35w to be safe. Thats going to be pretty low light and im not sure you will get the front to back coverage but I dont have any experience with this particular light. Most popular right now seems to be the current satellite which has some cool features. Honestly leds dont usually do too well with plants unless you buy a plant specific led and then they are pretty expensive. May be better off just going with t5 setup but its up to you. Atleast those leds arent too expensive if you find you need to add more

Looks great. If they make a 4 bulb it would probably save a bit of money because you will probably only want to run 2 or 4 bulbs at once unless you are going for demanding plants and co2. Keep in mind you may need 3 different spectrum bulbs as the actinics are useless but the timer is nice. Also because t5 lights have a nice even spread you can get away with a shorter one if you wanted(maybe 4'?). That light is good though because if you decide to try more difficult plants you shouldnt have any issues with lighting except for the most demanding of plants
