I was just through Onion a couple of hours ago and little time to catch my train to Nirvana, but took a close look at the lights in the VIA concourse (And I would have had more time if it had been indicated that I could walk right through to Platform 25 instead of going back, up ramp, through the GO York concourse and down again to get to what turns out to be the other end of the horrific VIA tunnel of visual torture). God help the poor tourist when even seasoned users of Onion don't know which way to peel it.
And here's the 'Tunnel of Torture": ("Glare Centrale" en français)

I had very little time to test the light characteristics, but the actual 'bulbs' are of 'fluorescent *SlimLine* configuration', button end:
Apparently DC fed, absolutely no sign of 'strobing' that I could find (didn't have time to use my tuning meter to 'beat' against the light, I have a Peterson tuner) and the 'tubes' are sleeved in a strange way with an open slit on the bottom side of most of the length of the sleeve.
My immediate question is: "Is there adequate UV protection?" below that slit. Ostensibly the plastic sleeve that encases most of the tube is a UV filter.
But before getting too deep into the physics and electronics at play, just look at the end product: I've seen welding shops lit up with better distributed light than this!
Do you wear glasses? Good freakin' luck not squinting to see through the reflections on your glasses. I wear wire rim glasses, and even though the lense edges are partially encased, each time I walked under one of those lights, it flashed through the entire lens edgewise. Blinding!
Really made me relax and want to shop. Not.
"Heritage" You betcha...just like Ford's Model T factories with raw light bulbs hanging from the ceiling. This looks just fffing awful!
Example, except this has fascinating machines to toy with, but the same blinding raw light:

Now the good news: The supply and fixtures are all in place to add *baffles* and "diffusers"...and with a slight loss of overall brightness, but a huge improvement in *visibility*: Fibre optic distribution for the light sources, or even edge lit panels that work the same way, moulded to deliver the light in gentle ways can be added. Is this meant to be a Soviet Tractor Factory basement, or a place of positive interchange and commerce?
All my cynical concerns of how Onion was going to botch the lighting were with merit it seems. I would have posted pics taken directly of the lights to show mechanical detail save that they were all saturated from the highly concentrated light source...
