With Great help from you guys, Light rack plan was finalized.

And after minor modification Light rack was finally done.

90 Degree crners used to fix the Lumenbrights in position



And a side by side comparison of the old Vs new reflectors



Should be back home in a week to suspend it and work on a pulley system to raise and lower the rack (Still not sure if I should automate or just keep it manual...) The good thing with Lumenbrights is that lights are already high from water level and allow you to work in the tank without needing to move them up each time unless you're doing extensive maintenance.

    Will use Rubber coated steel cables for support and this rope and Pulley rollers for the Pulley system.Rollers are rated for 50 KG (around 100 pounds each) so much more than the weight I have.






    When in normal operating height (Bulbs at 21" from water level for Lumenbrights) the pendants will be held by individual Steel cable from ceiling, and rack will be held by 6 Steel cables so no stress on the pully system. When/if I need more space for major maintenance or maybe when light acclimating the Pulley attached to 4 points on the rack will be of course supporting the complete weight. I'm notticing some beding in the rack du to missing support for the internal beam holding the MH so this will be corrected next week by adding additional supports so weight is better distributed.

    The Additional opening on top of the wood cabinets makes it really easy to work with lighting from above, lift up a pendant for cleaning or bulb maintenance instead of reaching from below.

    All pendants, Rack are attached to the cables and pulley rope by steel quick release attachement so the complete rack can be taken out in 5 min for maintenance. Just release the steel cables quick release, drop the rack with the pulley till its held on the tank bracing, disconnect Pulley quick release and then 2 persons can easily take it out.
    Will be adding a couple of roll bolts in the wall with quick release attachement which will make raising the rack to a specific height much easier, thinking 2 fixed points one at mid height and one at max height, which should be more than enough for added accessibility if I need to go in the tank and well as for 3 step light acclimation...
    And some pics from above


    Still need to take out the rack and reinforce it for the slight bending I'm seeing, as well as add support for T5 supplemental lighting.
