Just to finish off about my episode with the faulty light bar. I remedied the situation by buying an electronic ballast that ran the same number of tubes and wattage as the juwel bar.
This is a picture of the kit!
When I got the kit I stripped off the tube holders, all the wiring for the tubes and power, the protective black casing, and the on/off twitch.
First I had to complete the circuit where I removed the on/off switch and then I added all the original wiring from the light bar into the ballast with the help of my trusty soldering iron. When this was finished, it worked perfectly. Next, I siliconed the crap out of all the possible openings and put the bar back together. It still worked perfectly! and only cost me the bones of €30 to have the ballast delivered to my door.
Hope this is may help someone else as it costs a lot less then then buying a brand new bar. Plus there is no visible sign of the bar ever being opened apart from the bead of silicone on the underside.
