1865 watts at peak... (with the extra 440 watts of VHO added!!) but as I said...Peak....That is simulated as in nature....the lights go on in sequence....& peak @ 12:00-2:00
I have alot of equipment...most r dialed in to b the most effecient...Except for my skimmer....It uses 165 watts!!! that is why the bigger tanks have gone by the wayside!! (for the most part) If the hood didn't cost me 1800.00 in materials to build (without any bulbs sockets or ballasts) I may have considered going smaller....But...I probably wouldn't b happy.....
