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
Solid Investment By Corey on 11/9/2017Corey would recommend this product to a friendThis light has made an extreme and immediate improvement on my fuge. Cheato more than doubled in the first 20 days and my overnight Ph has gone from 7.95 to 8.13 after about 2 months of running the light. One of those rare products in this hobby that really did make a noticeable difference in the health and stability of my tank.
Great light but not always necessary By Nathan on 11/6/2017Nathan would recommend this product to a friendI have both a h380 and H80 on different tanks. I love the H80 and don't think you could go wrong with it. The H380 though is VERY strong. That's great if you have a huge fuge and room above to move the light around. The biggest issues are that there isn't a way to turn the power down which means you end up controlling the light either by height or by how long you run it. I am surprised there isn't an intensity setting and would like it even more if it had one.
My fuge is 24 x 24 x 24 but I still bleached my chaeto at first and had to shorten my light cycle down a lot. I definitely would go with the H80 over this if you have a small fuge.
Worth the investment By Matt on 10/27/2017Matt would recommend this product to a friendI have never had much luck with growing chaeto in my refugium until switching to this light, small compact and covers a large area with high intensity light. Operation is quiet and puts off a very minimal amount of heat. If you are considering using your refugium for your main nutrient export method then this light is what you need.
Awesome but loud By ricksastro on 10/18/2017ricksastro would recommend this product to a friendBought this a few months ago for a new Reefer 250 I'm starting up. My tank went through the cycle without any algae growth on the rocks (besides diatom dusting). My Chaeto grows in the sump like crazy. I started with a baseball sized clump and it's now filling my sump (about 12"x12"). I've harvested several softball sized clumps.
I will say though, when I first put in in the sump, it was quite loud, louder than anything else in my system. I could hear it with the doors closed. I even exchanged it for another one thinking it was an anomaly...they were identical. However over the last month, it has gotten a bit quieter and is no longer annoying.
Would have liked to see more features (dimming, controllability, better mounting options). I'm using the kessil gooseneck but had to ziptie the light to it...pretty janky.
It works By Tom on 10/16/2017Tom would recommend this product to a friendIf your looking to grow macroalgae this light is for you. I've had the light for about a month and my cheto has quadrupled in size. I run 12 on 12 off.
My only negative is that I can't adjust the intensity. But, I guess I wouldn't have the same kind of results if I could control this.
Unsure By Tanked out on 10/5/2017Tanked out wouldn't recommend this product to a friendI’ve been running this light for about a month. It worked great for the 1st week then my cheto started shrinking and green hair algae started growing in my fuge and green algae started growing in my display. I’ve been scraping the hair algae out of the my fuge. My nitrate and phosphate have also sky rocketed!
best of the best By PETRO on 10/5/2017PETRO would recommend this product to a friendlove it
expensive for what you get By spiraling on 9/17/2017spiraling would recommend this product to a friendI just got the light so I can't comment on how well it works. I have radions and am used to the features you get for about the same money. It is made well. I appreciate that the light disconnects form the cord so its easy to route the wires. You also get an extension cord piece. Looks great.
1 - this light is not at all programmable. Switching spectrums is manual, and you can't change the intensity at all. There is no timer.
2 - the fan on this light is pretty loud. Its louder than the 3 radions, or any of simmer or return pumps on my setup. If you are thinking of running it in bedroom or other quiet area it will be noticeable.
3 - hanging options are limited. There is an attachment in the center. That's it. It doesn't appear to be compatible with the kessil arms.
For the money, I would expect a bit more. Hopefully I'll have a refugium full of macro algae soon and will think it has better value
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
Ask a question
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!
