From the chart, it show that LED-G1-400-180W and LED-G1-400-160W equipped with 4 and 2 x 30W respectively.
My concern is coral placed below 10" on top of water line being burnt/melt/brown off due to the 30W LED ?
I like most is the control box that equipped with Lamp temperature display real-time detection, timer, separate lite control, over-temperature alarm and also the slim design ...!
Thump up for the product !
btw, It's a really good deal and option if you can't Diy and you still can help to save the EARTH !
