I have the older version of the 12 gal jbl nano cube. The ballast needs to be replaced - (we have a 4 pin double bulb with a blue & white light) - any suggestions where I can find a cheap replacement ballast?
This happened to me not too long ago on my 12g jbj dx. I had to order a similar brand and model from another company which specialized in lighting, I believe the ballast brand is PONY. I'll try to find that site for you.
The dx uses 4-pin linear configuration PC bulbs. It holds 2 24-watt bulbs right now.
