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!
Have a great day!
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
Outstanding! By g5flier on 8/27/2017g5flier would recommend this product to a friendPricey but what isn't that works? One week after installing this on my 20 gallon refugium and my chaeto growth is amazing, double in size in under a week. Saw Ryan yesterday at MACNA and we talked about the need of a skimmer at all after running this. Watch his video series on refugiums. Results are simply amazing!
Wow! By Joseph on 8/18/2017Joseph would recommend this product to a friendI have had this light on my tank almost exactly a week and I am very impressed. My Cheato has literally about doubled in size, just this week. Before I almost couldn't even tell if it had grown on the day to day. Very impressed and happy with this purchase.
I would highly recommend this light, great quality, great results!
KING OF REFUGIUM LIGHTING! By Brandon on 8/11/2017Brandon would recommend this product to a friendThis light is amazing! It's only been over my refugium for a week. During that time my baseball sized chaeto has grown to around the size of a soccer ball. Definitely get this light!
Awesome light By Jeffrey on 7/31/2017Jeffrey would recommend this product to a friendBought this from BRS 2 weeks ago and no joke my chaeto was about the size of a baseball had it under the H80 tuna flora and it wasn't growing now that it's under the 380 it has tripled in size in the past two weeks. Run 24hrs
Worth every Penny By David on 7/31/2017David would recommend this product to a friendI must say this light is performing better than expected. I just Installed it last week and have seen a noticeable increase in Chaeto growth. Also I wish I could upload a screen shot to show you my PH graph off my apex. From day one my PH now is a straight line, varying only a tenth from 8.4. Before this I was using a horticulture Par 38 pendent that claimed to be about the same wattage. Chaeto growth very slow and my PH varied from 8.0 at night to 8.4 at about 2pm. Time will tell what effect is on nutrient level but PH stability alone is worth it!
Very Effective By Tbone on 7/20/2017Tbone would recommend this product to a friendThis light has a noticeable effect on growing and blooming different plants while using little energy and producing very little heat. Spectral switches are user friendly and science/data driven for max effect.
Great light By Adam on 5/22/2017Adam would recommend this product to a friendI've tried several different bulbs over my refugium to grow chaeto and all worked so to speak but nothing has made it grow anywhere close to the rate it does with this light. Worth the price!
Works great! By Jan on 4/18/2017Jan would recommend this product to a friendI've had this lamp glowing purple over my cheato since 4/1/17 (2 weeks) and the growth has really been great. I would estimate that it has grown at least 2 times the size over this period.
Tremendously better than the $7 HD compact fluorescent I had been using. What really convinced me to drop all of that money on this light (which is expensive) was something Randy on BRS TV said. There was no way that my cheap HD light was able to compete with the 3x250 watt MH bulbs over my display tank. All of the algae was growing in my display and not in the refugium. Now my tumbling ball of cheato is growing beautifully!
Very happy with my purchase!
Expensive but worth it By Robert on 4/18/2017Robert would recommend this product to a friendVery expensive at $300 but i would highly recommend. This thing grows chaeto extremely fast and im always bringing a 5 gallon bucket full of chaeto to my LFS because there is so much. This light grows a nice soft chaeto as opposed to the other light i had.
Unbelievable Light By Alex on 4/10/2017Alex would recommend this product to a friendYes the price is expensive for a fuge light, but it pays off! My chaeto has absolutely exploded with growth under this light. It almost quadrupled in size in two weeks!
AMAZING-And Worth It By Michael on 3/30/2017Michael would recommend this product to a friendI know what you're thinking: $300 for a fuge light? I know. I know. I hemmed and hawed before I finally caved, and I'm so glad I did. This is incredible and does everything it claims (and then some). Trust me, if you have chaeto in your fuge, you want this light.
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.
