Retrofitting 2 x 4 Fluorescent Troffers from T12 to T8 components, it is suggested to maintain the Factory lead length and new shunted sockets to get the most out of the ballast and bulb lifespan.
I came across Fixtures that were T12 with the two leads on every socket with an T8 ballast. The original leads were full length from being cut off the old T12 Ballast and the Factory Length of wire from the T8 ballast were spliced without shortening anything. I am assuming it reduces the lifespan of ballast and tubes and wondering by how much? ...does this reduce light output? ..reduce ballast life by a percentage? ... burn out the tubes more quickly? ...potential for overworked ballast to cause a fire?
Thanks for any feedback!
