    Hello,

    I see all sorts of configurations with the Kessil H380 in so far as the height above the water and thus the area it would illuminate. I want to build a sump to ideally suit this light.

    Here is my current design concept:
    https://drive.google.com/open?id=19yWKqF77hbBL9T9PpBwks1LUByFuvusm

    - As in my diagram, I currently have an 18" diameter area under the light, but I don't know at what height the H380 will ideally work at, have not seen any info on the angle of the spread.
    - I see these used at anywhere between 7" and 24"
    - I chose 18" diameter chamber because that is about the biggest I can fit under my stand area, but if I could get away with 12" - 15" that would give me more room for other things.
    - If 18" is too small and I need to go larger, I will have to change the design.

    - Not sure about water height, seems somewhere around 12" is good, I am sure more does not hurt anything. I will maximize volume as much as I can.

    Any suggestions from BRS based on their extensive tests of this light would be appreciated.

    Elite Aquatics is building my custom Triton style method sump. Try them I’m sure they’ll come up with a great design for you.

    Also @jcl123 once you add all the elements together I think you’ll get a better visual as to what works for your setup.. may I ask more questions on your tank setup?
    Size of tank volume?
    Why the 2 refugiums?
    What are you goals?

    @jcl123 I'm going to see if I can get some of the numbers on PAR distribution for you. What I will say is that my observations have been that the massive power from the H380 tends to cause photosaturation/photoinhibition when they are mounted much closer than about 10" or so, but really only for the topmost later of algae. If you have the light mounted 10-12" off the water, you'll likely be fine, and get plenty of PAR/PUR, but the spread of the optics will likely give you greater than 18" of coverage. Do you plan to have smoked/blacked out panels for the fuge areas? If not, you'll likely see a lot of algae growth spilling into other compartments.

    I'm going to speak with some of the other guys here who've looked at the numbers we collected and get you a little more detailed answer in the next day or so.
