The induction in the Tunnel I must say is doing good....only 2 or 3 didn't work when I went through it and there must be over hundreds of them in that tunnel alone....And they are STILL bright....that's better than.....LEDs for sure....also there were less icetrons being out than the F96T12s found in the other tunnel which had more of them out!
im Sure General Electric isn't Infringing a Copyrighted Design...there had to be some sort of Agreement between the Two Companies for it to be going on as long as it has been.....the M400R3 Aint Bad Either...Better that than a Durastar.
