    MOD 420 is a universal frame for assembling a COB lamp with hundreds of different configurations.
    Developed by @Bobby from Mi and myself.

    The original prototype was Mod 8 for 8 cobs.

    We redesigned it to accommodate 4 cobs

    Assembly is quick and easy. No drilling, no tapping, no soldering, and no hassle.
    [​IMG]
    Start by bolting on the driver and junction box.

    [​IMG]
    The driver can be connected to the potentiometer (dimmer) and the AC power cord at this time using the Wago connectors that are supplied with the junction box.

    [​IMG]
    Next you can install the heatsinks on the frame.

    [​IMG]
    All wired up.

    With the exception of mounting the COBs to the heatsinks and installing optics thats the whole assembly. Takes about an hour. I left out the COB install do to there being so many options. We can get into that later on.

    Compatibility List

    Heatsinks
    Mod 4 is compatible with SST 105, SST 120, SST 140 and SST X
    SST 105 - is suitable for under driving cobs to 35 Watts or lower
    SST 120 - is suitable for driving cobs to 50 Watts or lower
    SST 140 - is suitable for driving cobs to 80 Watts or lower
    SST X - To be released in 5 weeks. Suitable for driving cobs to 120 Watts or lower

    Theses recommendations are on the conservative side and no air movement. You can dissipate more power as most grow spaces have a good airflow.

    It is a good idea to ground the frame. Yellow wire in the photo below.

    I have alot of people ask for a similar design. I have started to play around with the idea as far as where the driver, junction box would go. Thats as far as I've gotten do to ☝.

    Let me ask you this, what kind of COB spacing would you like to see in a design like this?
