    So after a nice talk with Jake Adams and some long though I have decided my LED's need an upgrade so here it is.
    [​IMG]
    I will be adding an additional 4 x 39w t5's to my 144w of led lighting.
    The reason for this is simple I wanted the best from both world's t5's have plenty to offer reefers as do led lights.

    Progress pictures to follow....

    PS! Do not miss out on Jake Adman's talks at the expo! you will be missing out!!!!

    Once I got the light frame, I can clad it in some wood to match the cladding on my tank that I am making :thumbup:

    I haven't been looking at light threads for a while but there 3 guys tonight alone mentioning going back to T5's or at least adding T5's to their led units. Is there a bigger movement back to T5's in general?

    It's that LEDs are point source emitters whereas T5 allows better coverage


    Hmm nice reflector idea :p

    Interesting, I have much better spread now with my LED unit compared to my metal halide and T5 combo that I used to run.

    i see all the big light unit players are going hybrid, it makes sense, gone are the days where LED units use less energy..
    i think over smaller tanks, 5ft <, they are fine but as one moves to the 2M and greater a combo works out more effective.

    The common factor that I see in all the units the guys were using and who are either switching back to T5 or adding T5 is that they use optics on the LEDs. This would make sense as the LEDs are more focused and therefor sacrificing spread.

    I am going T5/LED mostly because I can. Like any Reefer I want the best for my corals. To me is seems logical to use 2 diffrent technologies rather than limiting myself one.

    I still love my LED's and wont run a tank with out them especially when it comes to the colors they produce.

    optics or not, LEDs are point source, so unless you have a huge array like the Lani Leds you will always get some shadow and PAR drop as you move out the focal point my experience is that LED units cover a square area and most of our tanks are rectangular so the additional T5 or MH will definitely improve the spread and efficiency per wattt. LED cluster units , eg radion, vertex, will have to much focus in areas and a sharp drop as one moves to the edge of the cone.

    adding T5 allows better colouring tuning and a global light source that will help blend in the lensed LEDs

    The T5's will compliment My LED's. I am not moving away from LED's.
    I got some inspiration froms @carlosdeandrade tank which runs Pacific sun light unit. They look similar to this

    I've opted to go with out optics for my diy led build and I'm happy thus far, I've got no dark corners. But adding t5 will only benefit your tank. Have you tried to run your leds with out optics and closer to your tank?

    i ran 40 x 3w leds with no optics on my tank, 1 cm above the water...
    the spread was good, but only covered 800 x 400

    This is my tank under LED's the only shadows are what the corals cast themselves and the rocks. I use optics, the Leds are spread out on a 6inch x 9 inch heat sink. (most bought led's have their led's clustered) I doubt going without any optics would improve the situation much.

    [​IMG]

    this is the issue I am concerend with, and i saw the same happening on Nemo's Janitor's cube at the last reef meeting[​IMG]

    Notice in the red circle how the coral has died off due to the directional light it recieves, the Coral looks amazing and grows really fast.

    You are always going to have that issue of corals dying off at the base. I dont think adding extra T5s will solve the problem. Reason for me saying that is because the light still comes from the top. Yes you will get some more fill light at the bases but I doubt it will be enough to keep the tissue at the bases alive. The only way to keep the base alive is to put lights low down ( below the coral ) and get it to illuminate upwards.

    I know it wont solve the problem, but I want to test if it makes it less noticable. The worse case I have 4t5's extra on my tank.
