In short the light has been used on several of our tanks including the BRS 160 with success in keeping the algae growth constant without major pH swings between day and night. It certainly has worked on our systems but there are several other variable which can impact pH. Feel free to let us know if you have any further questions!
This light has a single knob to adjust the intensity of the fixture. There is only 2 spectrums included the grow(recommended for algae) and bloom which is strictly used in hydroponics or plant flowering. Feel free to let us know if you have any further questions!
Dense Matrix LED Technology
Kessil is a leader when it comes to LED lighting technology. With their Dense Matrix LED's producing a concentrated source of light, and switchable spectrum every wavelength within the spectrum is mixed perfectly allowing even and full growth. The H380 now has 30% more power than its predecessors allowing for deeper penetration and greater efficiency. The one fixture contains two unique full color spectrum blends with enhanced UV light.
Extreme Purple - Ideal for the growth phase of algae or plants. This spectrum will produce rapid growth while producing a lush, healthier algae. We suggest tuning the H380 closer to this spectrum to allow faster growth and uptake of nutrients.
Extreme Magenta - Targets the bloom stage, driving plants to increase quality and quantity of yield.
Dimensions - 4.5" x 4" (Length x Diameter)
Coverage - 24" surface diameter by 3' penetration (on average)
Power Supply - 100-240V AC (input) 19 VDC,4.74A (output)
Power Consumption - 90w max
Note: Not compatible with Spectral Controller
Wow what a light! By RobertP on 3/13/2017RobertP would recommend this product to a friendYeah it is expensive but it is worth it. I had the clip on light wirh a led grow bulb and my chaeto was growing a little but slow. Had this kessil in a week on the same 12 hr schedule and the chaeto doubled. I left it in another week and the chaeto is a thick mat. Great way to export nitrates and phos.
Excellent By Johnny H on 3/4/2017Johnny H would recommend this product to a friendAlgae isn't the only thing it grows
Wow By Jon on 2/10/2017Jon would recommend this product to a friendLet's just say it works and by that i mean the results are amazing algae growth. You won't be disappointed with this purchase.
Grows Like wildfire! By Mark on 1/29/2017Mark would recommend this product to a friendI installed this light over my sump refugium about one month ago and could not be happier with the results. My chaeto has grown into a thick mat and I just have the light coming on periodically throughout the day for maybe an hour or so or less. I am growing enough chaeto to add to my main display tank so no more buying chaeto for me at this point, it seems. It is working out so well that I am about to buy another one for my main display.
Of course there are cheaper options here but I like my whole reef tank setup to look like a beautiful well-built setup and not some sort of Frankenstein laboratory contraption. I c ould buy a cheap light from home depot to grow chaeto but ain't nothing like opening my sump cabinet and seeing that nice, sleek looking Kessil H380 hanging there.
Nice light By Daniel on 12/31/2016Daniel would recommend this product to a friendI purchased this light in hopes of growing my chaeto in my refugium more aggressively. I have a 135 gallon tank with a sump and a separate 15 gallon refugium. I have been running the light for 16 hour periods for a little over 2 weeks now. My chaeto has probably doubled in size during that period, but I started with only a small softball size clump. Previously, though, my chaeto had pretty much stalled in growth but I was only running 12 watts of white LED's on it. Other reviews I've read talk about having much greater growth than I have experienced, but I suspect that is more a result of my ultra low nutrient system (nitrate is typically 1 ppm - 2 ppm, and my phosphate levels are less than 0.01 ppm).
Great Light By Newt on 12/10/2016Newt would recommend this product to a friendI struggled for years getting cheato to grow. I have tried many different bulbs and setups with limited to no success. I put this light over my sump and instantly my cheato started to grow like crazy. In fact it doubled within a week. I was very impressed. It's price was at a premium, but for the results well worth it.
GROWS CHAETO 1000 PAR By SNOTDOC on 12/9/2016SNOTDOC would recommend this product to a friendThis thing is insane. It puts out over 1000 PAR about 10" below the light as measured with the Apex meter. It grows so much chaeto I need a larger fuge.
great light By medtoad on 9/16/2016medtoad would recommend this product to a friendI love this light. Not only does it produce this cool glow out of my maintainence room, but my Cheoto grows like wildfire. Grows so fast that it actually accumulates oxygen bubbles on it. I called kessil and they stated the "a series" gooseneck also worked with this light. Well, sort of. It comes with some quick ties you can attach to the piece that screws onto the end of the gooseneck that worked well to hang the light. Additionally, I had to modify the rim of my sump to make the gooseneck attachment fit. Prior to this light, I had some problems with cyanobacteria growing on my Cheato, but that has gone away as the wavelengths Cyano needs are not present. Overall, I'd have to say this light was worth the investment.
Ridiculous Growth With This Light By Barrett on 6/15/2016Barrett would recommend this product to a friendSo, 1.5 weeks ago I put this on my new 180 gallon setup with the sump below. I had a large softball size ball of chaeto, I put this on when starting the tank and 1.5 weeks later, the entire refugium area is covered in chaeto. I sold it to my LFS for $26 bucks only after 1.5 weeks... this light will pay itself off. I had an LED light on my old 90 that would take MONTHS to do what this light did in 1.5 weeks. Highly recommend and if you want extremely rapid growth for your chaeto. I don't normally buy into a product this pricey just to grow algae but this is amazing.
Great light By Jmc on 5/23/2016Jmc would recommend this product to a friendThis light grows my micro algae like wildfire. Pricey but performed on price point
