    hey hoppy. love your work, the led guru. i would like to upgrade my led fixture. i have done a DIY one before and thanks for your help on that one. at the moment i am i am running 12 cree XML-t6 at 700ma. what i was thinking of is buying 2 of these http://www.rapidled.com/mean-well-lp...urrent-driver/ and running 9 of the cree xml-t6's of each of these and building the heatsink myself. this is going over a 4 foot med planted 60g tank, dosing dry ferts and co2 injected.

    what i wanted to ask your help on is
    1. is there a better driver out there that i just cant seem to find that will save me from having to wire up 2 sets of 9 at 1750ma
    2. is this going to be overkill on the lights?
    3. what would be the best way to arrange them. i was thinking two 4inch wide heatsinks running the length of the tank. if the tank is 18inchs wide then one running say 6inchs from the front and the other 12 inchs from the front.

    thanks man for any help you can offer

    I have never grown HC, and my experience with glosso was limited to trying out the dry start method. So, I can't comment on use of T5NOs for growing HC/glosso. I also have never used NO lighting, so I can't comment based on my experience with them for growing any plants.

    In your experience, can T5NOs grow HC/glosso carpets or ludwigia?

    Hm, here's a link to his site:

    You probably don't know him, or you would've recognized his name instantly. :P

    Hey, do you know Ned of Uncle Ned's in MA? Your avatar really reminds me of the one from his website homepage.

    treelimbjim, that other post was done back when I was still trying to make sense out of designing a LED light. I wouldn't recommend following that method now. The calculator is based on more data and more varied data. If you have taken some PAR measurements with other configurations I would appreciate receiving the data so I can see how it fits in with the other data I have.

    This is still an evolving design process, but I haven't seen a better process.

    Thank you for your contributions.

    Trying to answer "How many (and type) LEDs to use my 70 gal?" or simply, "Is 24 XPG enough? 36?"

    I've been estimating with spreadsheet V.3.

    Tank: 48wx18dx20h, 3" substrate

    Frame: 1.5" aluminum extrusions, 3 x 48" rails on 5.25" centers.

    Mod/add:
    Table for PAR est. for L,M,H light (see below)
    LED height: Tank_height + LED_Height_above_water - Substrate_depth
    Conditional format: 1) PAR background is blue, green, orange for L,M,H light. 2) current background is red when >rating.
    Table for Spread with LED_Height and Cone_Angle

    I'm not clear about how the "rows" work. I'm trying the geometric mean of LED_spacing and my LED_row_spacing.
    Trying to validate the calculations, I ran across 84212-designing-building-led-fixture-22.html#post1102937
    ... and the spreadsheet isn't coming close to real world observations.

    Where to go from here?

    Mark,
    The number and spacing of LEDs for any size tank can be calculated with reasonable accuracy using a Excel Spreadsheet "calculator" shown here: http://www.plantedtank.net/forums/di...ml#post1803323 I doubt that you will want to use Cree XP-G LEDs for that small a tank. Perhaps XR-E would be a better choice.

    Hello Hoppy,

    I understand you are the aquarium lighting mentor. I was sent over here from Nano Reef by Evilc66. I am looking for some help with the lighting for my Aquarium.


    I am new to the aquarium/lighting arena. I have a Fluval 12 gallon tank with fresh water. I am wanting to grow some high light plants and carpet plants.

    I am considering a DIY modification to the lighting. I am looking into getting the CREE XP-G LED's. What do you think is the appropriate amount of cool white led's and the total amount of watts/lumens for the 12 gallon?

    Your input is appreciated!

    Cheers.

    Mark
