- H380 Halo II LED Algae Grow Light - Kessil
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.
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)

Very Disappointing By Pete on 6/28/2018Pete would recommend this product to a friendI purchased this light from BRS 14 months ago. It was easy to install and I was hopeful that it would do everything people (BRS included) claimed. It grew macro algae well, but not much better than my previous refugium LEDs which were around 1/6th the price of this light. Moreover, It has only been 14 months and the fan in the light has stopped working which essentially means the light overheats very quickly and shuts off after less than one minute. I realize the death of my light is from the saltwater environment, but I was very cautious when I got it and mounted it to avoid and problems For over $300, I would expect the light to function extremely well and to last more than 14 months. Essentially I wasted a huge amount of money thinking this light would be great, but it only performed slightly better than my previous cheap LEDs and it died after just over one year of use! Save your money and get something else.
Simply the Best By Kevin R on 3/29/2018Kevin R would recommend this product to a friendGreat product. As soon as the light went above my refugium, it made a huge difference. My Chaeto just about doubled in the first couple of weeks. I've seen a vast improvement in the efficiency of the refugium with this light. I would recommend it to anyone looking to increase the growth rate of their Chaeto in their refugium.
Disappointed By Whiskeyboy84 on 3/27/2018Whiskeyboy84 would recommend this product to a friendI will start out by saying I am a new reefer and am building a 250g system with a custom built sump to leverage the Triton Method that said I have a 35g fuge that is 30” long so I ordered two H380’s and an H series spectral controller that one would assume is compatible with the lights similar to the A360 and the A series controller and to my surprise they aren’t so if you need multiple lights for your fuge know an Apex or timers are in your future!
under powered By Tran on 3/26/2018Tran wouldn't recommend this product to a friendpower supply gets very hot, to hot
Great product By Psustein on 3/10/2018Psustein would recommend this product to a friendThis light packs a lot of punch, and very quiet while running. The spread is nice and more then sufficient for any sump.
Game Changer By David T. on 3/8/2018David T. would recommend this product to a friendThis was a game changer for me. I use it on my Reefer Peninsula 500; Nitrates and Phosphates are consistently at 0 and less than 0.3 respectively. It does add some heat to the tank given the light is in the closed cabinet, but the addition of a small DC fan to keep air flowing in/out of the sump are fixed the issue completely. I recommend this light every chance I get.
So far so good By richard on 2/24/2018richard would recommend this product to a friendI've used clip ons for years so I wanted to try this because brs TV only thing I wish is if the could make it adjustable to acclimate everything or make a diffuser the will just snap on that will dim it down a bit to help with the acclimation it does produce a little heat but no more then my clip on and mounting it was a breeze quality is second to none only time will tell if it was worth the investment
WOW! By Colin on 1/29/2018Colin would recommend this product to a friendBecause I have never had the best luck with growing macro in a fuge I was a little hesitant to spend $300 on a light. All I can say is wow, this thing grows chaeto like no other. I have been battling a little algae since getting lazy and needed to fight back before it got worse. I added this light along with a very small baggie of chaeto, and within a week the chaeto is almost he size of a volleyball. I have been running it 24/7 and my algae has stopped growing and will hopefully begin to go away soon. The only thing I don't like about the H380 is that it lacks the ability to turn it down. Although I wanted to have some overkill power I wish that once my chaeto is fully established I could maybe put it down to half power to reduce the heat put into the tank. Besides that the light has exceeded my expectations! if you are in need of growing some macro quick, quit thinking and buy this thing!!
Seems to shrink my Chaeto By Salty on 1/26/2018Salty wouldn't recommend this product to a friendI bought this light after watching the BRS TV episodes testing the fuge lighting. The light is extremely bright and very hot. I also purchased the arm and 90 degree attachment hoping that it would be the perfect set up for my new trigger emerald sump. However it seems to shrink my Chaeto and increase the water temp. I spent a lot on this light and had better results with a clip on light and a light bulb. Bummer
Pricey but worth it By Chris on 1/5/2018Chris would recommend this product to a friendI am in the process of converting my main display tank to the Triton method. My sump is a little over 60 gallons and the lighting i had in there I thought was good enough, I was wrong. Prior to adding the H380, the Apex would report a peak pH of about 8.15@6:15PM every day and low of 7.90@5:00am. I had the previous fuge light set to run opposite of the main DT lights. The day I added H380 the low pH stabilized to low 8.0 with no other changes. The chaeto is growing like crazy as well, easily doubled in two weeks. After three weeks the pH is stabiled to a high 8.28 and low of 8.2.
Mounting was easy with the flex neck, ample cable length, and it's simple on/off setting makes it easy to just configure a outlet on the apex to turn on and off. I cannot recommend this fuge light enough.
Incredible Refugium Grow Light By Kyle on 12/21/2017Kyle would recommend this product to a friendThis is an extremely effective, yet dead simple and hassle free refugium grow light. I bought and installed it on my new Red Sea Reefer Peninsula 650 system that I recently set up and have been running for almost 4 months now. I have 33 fish of various types in the system, ranging from a couple Tangs, a few wrasses, to a school of 20 chromis and anthias, plus a decent amount of various types of coral, and I have always had zero nitrates (using API test kit), and nearly zero phosphates. I couldn't be happier with this light. This has been by far the most stable and consistent system I have run, and I attribute this to the grow light. My chaeto has grown shockingly fast, and though I harvest it bi-weekly I could harvest weekly. Many people complain of the lack of features, but I personally appreciate that it is dead simple. You simply turn it on and select from one of 2 pre calibrated modes: grow or bloom. Kessil did the hard work and found the very best spectrum blend for each mode, and I love that. No calibrating to do, settings to adjust, or spectrums to tune. Simply plugged it into my Apex, set the on/off times, and I had a truly amazing fuge light set up perfectly. It's perfect, and I couldn't recommend it more! GET THIS LIGHT, YOU WILL NOT REGRET IT!
Best ever By Joe on 12/13/2017Joe would recommend this product to a friendI've been running my refugium for 3+ years using an led grow light. My Chaeto growth, I thought was ok but I continuously had nitrate readings of 5+ and phosphate of .02. After replacing the light with the H380, I get a months growth in about 5 days and my nitrates and phosphate are nonexistent. I really recommend this light
HI, I would like to buy one, but can you tell me more about noise level, thanks Nick.
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?
Do you recommend running light 24/7 (if used for refugium)? If not, I will need a separate timer? Thanks.
Is this available in white by chance?
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?
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!
Can this light be controlled with the Apex Neptune controller?
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.
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!
My H380 came with an ac adapter that differs slightly from the manual specs.
Specs: Input 100-240 VAC 47-63 Hz 1.5 A MAX Output 19 VDC, 4.74 A
Actual: Input 100-240 V 50-60 Hz ~1.6 A Output 19.5 V 4.62 A Max. 90 W
Can someone confirm this is the correct ac adapter?
Thank you for reaching out with your question.
The power supply that was provided with your light is the correct AC adapter. Manufacturers sometimes make small changes to the product and accessories after the manuals are printed. That adapter will work with that light with out any issues.
Let us know if you have any questions!
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!
Have a great day!
