Quick Overview

Growing macro algae in your refugium or sump can help reduce nitrate and phosphate levels in your saltwater tank while providing a safe harbor for micro-fauna to thrive.


The Halo II H380 has been specifically designed to emit a spectrum that will allow algae and other plants to grow to their fullest potential by targeting the wavelengths and spectrum required. The H380 does have the ability to change spectrum, that will allow you to fine tune the lighting for the best growth of your specific type of algae. Allowing faster growth will, therefore, allow the algae to remove more nutrients from the water column.


With the different types of Kessil mounting options, like the gooseneck, mounting the H380 is super easy and can mount on almost any sump or in any location.


 


Note: Mounting options sold separately.

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.

 

Switchable Spectrum

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.

  • Solid Investment By Corey on 11/9/2017

    This 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 11/6/2017

    I 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 10/27/2017

    I 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 10/18/2017

    Bought 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 10/16/2017

    If 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 10/5/2017

    I’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 10/5/2017

    love it
  • expensive for what you get By spiraling on 9/17/2017

    I 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 8/27/2017

    Pricey 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 8/18/2017

    I 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 8/11/2017

    This 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 7/31/2017

    Bought 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

Product Questions

I have a small separate refugium area with this light over it. I was considering adding a clam, but i was unsure if this type of light would support a clam. Any ideas?
Question by: Daniel on Jan 24, 2017 9:31:00 AM
Hey there! This light is primarily used for algae growth and not for life support for inhabitants like clams. The biggest concern, besides proper life support spectrum, is that the ever growing algae will eventually take over the clam and starve/over crowd it until it dies. I wouldn't advise it. :-)
Answer by: Admin (Admin) on Jan 28, 2017 7:29:00 AM
Do you recommend running light 24/7 (if used for refugium)? If not, I will need a separate timer? Thanks.
Question by: Floyd Fortuin on Jul 1, 2016 12:05:00 PM
We recommend 18 hours of maximum refugium lighting per day. A timer will be a perfect option for this!
Answer by: Connor (Admin) on Jul 1, 2016 12:46:00 PM
Is this available in white by chance?
Question by: Joe on Jul 1, 2016 8:04:00 PM
Right now, Kessil is only offering the black for this model.
Answer by: Valerie W (Admin) on Jul 5, 2016 11:59:00 AM
Does this light provide the spectrum of light needed to help maintain pH stability in the system when the Display tank lights are turned off? Looking for a light that can provide maximum algae growth and pH stability in the system, any suggestions?
Question by: Hunter on Jul 2, 2016 6:45:00 PM
Great question and tough to answer!
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!
Answer by: Connor (Admin) on Jul 6, 2016 12:23:00 PM
Can this light be controlled with the Apex Neptune controller?
Question by: John Bays on Dec 30, 2016 11:25:00 AM
Great question! You will only be able to control the ON/OFF functionality of this light with the Neptune Apex. This does not work with the 0-10V variable speed ports.
Answer by: Randy (Admin) on Jan 9, 2017 8:59:00 PM
How is the intensity/spectrum controlled on this light? I plan to use it as a refugium light as suggested on BRS series but concerned about how close it will be hung (given stand height restriction) vs shallow refugium height.
Question by: Elisabeth Duarte on Apr 17, 2016 2:05:00 AM
Great question!
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!
Answer by: Connor (Admin) on Apr 20, 2016 3:19:00 PM
I'm a bit new to the refugium setup within a sump. How would you typically mount a light like this to a refugium within an acrylic sump? Does it come with some kind of mount? Also, do you need to have dark panels separating the refugium from other sections of the sump so algae doesn't grow in the Protein Skimmer and Return sections of the pump? Thanks!
Question by: Mike Sharp on May 23, 2017 1:06:00 PM
The easiest way to mount this light in most setups will be to use the gooseneck mount and clamp to the side of the sump.

Have a great day!
Answer by: Zack (Admin) on May 30, 2017 2:23:00 PM
Controllable (Apex?).
Question by: Luke on Jan 1, 2017 11:54:00 PM
Great question! It is not controllable with the Apex nor the Kessil Spectral Controller.
