There are many different brands of LED
, that would work. Ranging in price from about $200-$600, per 20" unit. Many people have had good luck with the Taotronics dimmable 120w unit, bottom of the price point. Others, who can afford it, love the Radions by Ecotech, near top of the price point.
Besides those a 4 bulb 24" T5 unit (30" overall ), would work as well.
Both would light your tank quite well. The T5 might not do some higher light SPS
, but would definitely work with some lower light SPS
being the most light demanding of all.
