Today's Newsday had an article about a new public backlash re: the LED lighting in the M9's being too bright and glaring. I said to myself, just wait a few years 'til the lenses get dirty and then the lights won't seem as bright. LOL
Also said there are now three M9 trains in revenue service. Progress........
It is a bit of an eye opener (pun intended), I thought the same things when the M7s came into service. However, over time, fluorescent lamps lose output, especially in constant use like on the trains. On top of that, the acrylic lenses yellow a bit. You can tell which lamps were recently replaced as they're brighter than the rest.
I dont believe the M9 LED will loose output, we'll see about the lenses yellowing however.
