I picked up a Used Odeyssea 4XPC fixture a while back. It never worked right and I was contemplating getting new ballast or tossing it. Ran across a few DIY LED threads and decided what the heck.
Started by gutting out the original... it was different than I thought as it had a separate compartment for the Ballasts. In one way nice but limited size for LED Drivers. Note the cutoff setions to reduce from 24" fixture to 20".
Basically I salvaged encaps and housing. Fans were replaced by 10DB units I found.
heatsink is 5 X 17. Purchased a diablo metal blade to cut heatsink for clearances. Cut back a few fins and later cut out the rear three for wire runs.
Soldered layout on board matched to heatsink 12 cool whites and 12 royal blues
Lights attached using thermal epoxy. Heatsink attached to housing using original T-tracs. Modified a few #8 screws to work in trac. You can see here where last three fins were removed
Power housing attached. Used Sunpark 120-27000 Divers that use 120V eliminating need for additional power supply. Will use meanwell in future to allow dimming feature.
Leads attached and endcaps on.... Lights on... WOW! this is one bright fixture now...
Just need to fix legs where previous owner cut tabs off. then will mount on tank.. Tired for now... tank test later
