As an electrician, I can tell you that A is way too dim. You need that space well-lit for troubleshooting and maintenance.

Haha, I bet the person who wrote this question is a lighting enthusiast. 'Foot-candles' - who uses that unit these days?

Hmm, I'm torn between B and D. Both have high lux levels, but D might be overkill. I'll have to think this one through.

D is definitely the way to go. Symmetry between the horizontal and vertical planes is important for optimal lighting in these areas.

I'm not sure, but I think C) 500 lux in the horizontal plane and 200 lux in the vertical plane makes more sense.

Option A seems a bit too low for a telecommunications space. I'd go with something a little brighter to ensure good visibility.
