Regarding LEDs, you can get good quality LEDs that are dimmable but not programmable for about $120-160 per unit (1 is good for every 2 ft of tank) on eBay. Look for the 120W (Taotrinics) units. They are the go to unit for many of our experienced reefers (doug included). Pricier units will do ramp up in intensity and lightning storms for only 4 times the price. Most have about a 1:1 White:blue LED ratio
