Flourescent lighting
(OP)
I have a problem with a batch of flouresecnt lights with LG3 Diffusers installed on a steel clad insulated ceiling.
On inspection the wiring around the choke/ballasts tends to be brittle and cracked. The terminals on the choke are brown in colour. Quite strange is how the red phase wiring is also cracked and brittle and the blck neutral cable is unaffected. The installation is about 3 years old the starter is also becoming brown.
As the risk of fire is greatly increased has anyone else had simiar problems please advise ???

The rule of thumb is that for every 10 degrees higher, the speed of a chemical reaction doubles. So if something is heating the other wires say, a measly ten degrees higher, then essentially(chemically) the black wire is only half as old! It may end up looking the same in twice the time.
Also black is the best radiator of heat. Substantially better than any and all other colors. This means you could actually expect the black to be a little cooler.
And lastly the black formulation may just happen to be a more durable color.
Summation: I wouldn't read too much into the fact that the black wires don't look as bad as the rest.

Which is due to slighting "open" design of surface mounted 6ft LG3 luminaire.

For general interest, in the 8-14 micron infrared range, (<100 degC) the emissivity of PVC is 0.91 - 0.93 and matte black lacquer paint is 0.97 while white lacquer is 0.92, only 5% different. The pigment and surface in most other paints fall around these values too.
