I'm in favour of lighting. I don't want Vancouver to become Las Vegas by any means but I see lighting as an architectural design element and if done well it can add a lot to a building.
I'm not a fan of light pollution or wasting energy but LED technology requires very little energy and throws off very little ambient light so it's really the best of both worlds in this regard. And if nice lighting makes people happy (it makes me happy) then it's worth it in my mind. Also, in a city as grey and rainy for half the year as Vancouver it really helps combat the depressing dreariness.
I don't need to see lighting on every other new building but it would be nice to have some sort of (tasteful) lighting on the Shangri-La to add some interest to what is now a tall and iconic tower for Vancouver.
Anyways, it's not the end of the world if it gets some sort of lighting element or not. I'll still like the Shangri-La and I'll still have other buildings to look forward to like the Hotel Georgia and West Pender Place that will add some more lighting to the city.
