Kessil is showing off their new matrix LED powered lights that utilize the DiCon Dense Matrix LED array.  These 90W lights combine Sky Blue and Deep Ocean Blue colored LEDs and allow you to dial in the level of blue you want.  The 350 has a 31˚ optic which is designed to punch into tanks that are deeper than 24″, whereas the 350W (or Wide) sports a 70˚ lens for covering a large swath of tank but with limited depth.  The low power consumption makes the 350W ideal for lighting shallow frag tanks.  These new lights should be available in the next two weeks from Kessil and most retailers.
