Well done Brendan
You have certainly got their attention & you have opened up a useful Dialog. That will be by far the most effective way of dealing with the issue.
I would be interested to see a picture of the lights they are using ?
It may well be, that if they chose an "Architectural Light" rather than an "Industrial Light" they would get a much better result. Using less Energy, with a much lower "Upward waste light Ratio" these thing can be calculated by the supplier of the lights, a computer program is used to do this.
I will be very interested to see the lighting Engineers responce.
The usual way light fittings are chosen on large industrial sites is "what do we have in the warehouse", "are they the biggest ones", "yep, install them"
I know this from first hand experience
