ok i have some older nano's like 12 and 28 gallon with the pc's for lighting built in the attached canopies and the need to be upgraded to led retro type setup . Who makes them and what do they usually run would like to just gut what i have and install the leds to fit using the same canopy. If you have done this can you post some pics and share some intel on what it took to get this done tech wise and cost..thanks for any intel regarding this upgrade . also are you happy you did it?
