http://brs.li/ledkessil Kessil LEDs produce an amazing shimmer, have a compact design and the color and intensity can be easily adjusted with just a turn of a dial. Today on BRStv, we are going to take an in-depth look at Kessil LEDs including external appeal, internal appeal, control, cost per led, build quality, warranty support and finally finish with a few details on how many you would need for your tank and which model to get from the A360 Narrow and Wide, the A350 Narrow and Wide or the A150 in Deep Ocean Blue, Ocean Blue, Sky Blue or Amazon Sun.
Most people will be best served with the wide version which spreads light out 140 degrees and covers a two foot area down to 30″. The wider angle also allows you to place them closer to the water in tight environments like a lower profile hood.
The A360N or narrow version has a reflector on the pendant which focuses the light to a much sharper 60 degrees spread and covers a 18″ area. The focused light increases the PAR and ideal for tanks over 30″ deep. If you are looking to have a SPS dominant tank you may also appreciate the higher overall PAR numbers by selecting the narrow version and spacing them 18 inches apart.
Kessil LEDs are produced by Dicon Industries located in the San Francisco area. They have been experts in lighting and optics for years and this shows in the design of the Kessil LEDs.
Kessil LEDs are compact and best of all they are easily hung above the tank or you can use the Kessil A Series Gooseneck to attach it to a rimmed or rimless tank. The natural shimmer lines produced by the Kessil is rivals metal halides but with the controllability of LEDs.
The color blending is amazing. With many LED’s you end up seeing red and green specs of light floating all over or the back of the tank that looks like it is on fire. With the Kessil A360 you don’t see that because all of the LEDs are packed so tightly together under a single lens. The Kessil A360 can be controlled with your Apex from Neptune Systems or ReefKeeper from Digital Aquatics.
Kessils come in a really compact form factor with a fan and heat sink mounted directly to the LEDs. Each light has a large volume of thin fins on the heat sink which do get warm to the touch but not hot. The base plate does get warm up a bit if left on long enough. The fan is silent and while it doesn’t move an enormous amount of air it does seem well optimized for the heat sink because the fins are only warm even after being left on for a long period of time.
Overall the cooling system and overall build quality for such a small form factor present an excellent value, especially at this price point – plus they come with a 1 year warranty
