My tank is set up too close to my heat vent and I cant keep the temp down so I bought an external LED light. I bought these maybe 3-4 months ago. I got the retro with dimmable ballasts (0 to 10V) and after fighting with my RK-ALC for too long I bought non-dimmable ballasts too. This kit needs a few of the LEDs replaced, which is pretty easy with a retro. Asking $120 with both dimmable and non-dimmable ballasts. Pick up in or near Ventura only.
