KessilA80 Tuna Sun LED Light

Lights are fanless and completely quiet (compared to the Kessil A160's fan, which is audible across the room). You do need to buy 3 of these, to replace 1 Kessil A160, so it's not very economical in that respect. But reducing room noise was a priority for me, so the extra money was well spent.

I almost didn't purchase it, because there aren't many reviews and the few that I've read are only fair. For my three gallon brackish bowl, I decided to take a chance on it. I am not the least bit disappointed. Based on reviews, I thought I would have to have it on something like 14 hours and at full intensity, but I was growing way more algae than I needed. I put it at the lowest intensity, and decided even then, that 12 hours was way too long to have it on. I currently have it on for 10 hours and may raise it higher than 4" above the water.My complains:At $129.00, the gooseneck (which has cheap plastic screws, that I'll probably replace with real ones from Home Depot) should've been included.There is no shimmer that I've noticed.Being that I keep it at the lowest intensity and the color set at yellow, I don't see a point to the Spectral Controller when a regular timer works just fine.

This is my first Kessil product so I really have nothing else to compare it to. I like the form factor. I really wish I didn't have to purchase the goose neck but honestly It was my only option for mounting this thing. I have a mounted to a 7.5 gallon rimless tank with C02. So far my plants are growing but I did notice that they tend not to pearl when I use the gooseneck so instead I mounted the gooseneck to the table and the light sits about 2 inches from the waterline. For my application the gooseneck was basically useless.

Great light with great shimmer. Quality product. You get what you pay for with this.

My Amazon Swords are finally growing. This light did the trick.

Nice

The media could not be loaded. This is my 8 gallon tank,but realistically has no more than five gallons water in it. It's been up for almost 1 year. My corals are doing amazing. I leave the light on for 9 hours a day. The light has 2 knobs and is on a regular timer. So easy it's unbelievable. One of the best lights and tanks I've ever had.

I decided to be an early adopter and it was too early. There are videos online of someone using 3 of the marine model to light a 120p tank at Macna. A few reviews mentioned this being "half" a 160. Having a single 160 over a tank at 50% intensity, I decided to take a chance.The form factor is great. Has the same ports and dials as the 160 and 320.Mounting is not. The 160 and 320 have screws on the top, allowing for it to be mounted a few different ways.Out of the box, the only way to mount the a80 is to a canopy. With no screws on top, you will have to diy a hanging kit through the heat sink slots. You can buy a gooseneck for this.Now for the light itself. It's not half a 160. I unfortunately do not have a par meter, but this light barely penetrates to 12 inches.This is a problem, as the pictures released of the light cone by kessil show it can light 24 by 24 inches and there is no way this light can adequately do that depth with even fish only with no plants.
