    Hello all

    as some of you know I am doing a sunlit tank but still need to add some blue light to my water. I was going to go with MH lighting 2 x 250W 20K blue

    what LED lights could I use that don't take up the whole tank? that are 20K blue?

    I need to know prices of such units as well

    thanks

    Cant remember seeing just blue led fixtures

    Why not just DIY a row of royal blue LED's and if you use the meanwell D drivers you can dimm with your profilux

    You guys wont know of pendants since you are DIY junkies :)

    There are a few units that come out in the 20K range. Orphek DIF pendants (same ones Adee has over his tank) come in a range of kelvins including 20K and even 25K. Not sure on pricing, you will have to ask Adee.

    I know Kessil also make a blue one but I dont know much about it.

    You can always have a look here if you want to build your own DIY Pendant with a 50W LED.
    This one LED contains both blue and white and you can fix the ratios as needed to get the right colour.
