These lights are probably on the border between mid level pricing and the Elite lighting systems, coming in at around $400 each, but I couldn’t do an LED lighting write-up without them. The new E-series LEDs from Kessil are great lights and will really make your tank pop. Most people are used to longer strip lighting systems that cover the whole tank, but these lights are just pendants. This means you will need at least 1 to 2 feet of clearance above your aquarium for them to hang in order to get the maximum suggested coverage (24″ for the W model and 18″ for the N model)
Kessil also gives you a few different ways to control these lights which a lot of companies tend to overlook. You can control them manually with the two dials on the light (one for color and the other for intensity.) You can also use a number of different external controllers to control them, including Neptune’s Apex system or Kessil’s Spectral Controller.
If you like the Kessil A360 but won’t be keeping a lot of stony corals, or are planning on more of a softie/mixed reef tank, I would suggest looking at the Kessil A160WE Light. It offers great color and similar coverage to the A360, but you will save a few hundred bucks on lighting.
Keep in mind that with a 24″ max coverage radius you will need to purchase multiple units for larger tanks and the distance between the lights will sometimes create a shadow effect between them if you do not have the lights high enough or if you hang them too far apart. The one caveat I need to mention about hanging lights very high off the tank (any lighting system) is that you will be wasting a lot of light on the front and back walls of the aquarium, and this will create excess algae. You need to find the sweet spot that will allow you to get good side to side coverage without too much direct light on the front glass. This is especially hard in some of the more narrow tanks.
