Australia will be recalling all LED Tube light fittings in the next couple of months for all government buildings due to eletrocution and or shock. It may be an Idea to keep both active and neutral at the same end but be interchanging so it does not matter at which end of the tube is fitted to the fixture. Also so if the fitter puts their hands on the other end they don't get electrocuted.
One company is currently designing tubes with a 50% faster conversion rate with the safety modifications. If you do not want your suppliers in Australia to loose out better snap to it.
