Very interesting. I've never seen these things Paul. How do you power the tubes and is there a wiring harness that's removable from the normal fixture like Kinos? The BM site is pretty weak: http://www.bmlighting.com/new/products/mac-tech-led/mac-tech-led-series-overview/Avoid mid day sun. That is when your ratios from interior light to exterior is at it's worst. Work early morning late afternoon. I have been using Bardwell McAllister LED tubes for awhile now. They are very bright and quite a bit cheaper that light panels. They are the size of Flo tubes and come in various lengths starting at 12 inches. Buy a cheap cig lighter inverter and a roll of velcro and stick them anywhere. They are light and unbreakable
