hmm we have actually used LED for many units in natura loft and park central dbss.. but we mostly specialise in LED downlights or LED strips.. seldom use LED tubes.. in fact most of our feature walls uses LED strips because it is much thinner and easier to conceal and takes up lesser space.. haha not mentioning more fun to switch around with the colours! to be honest, any spoilt item shouldnt it be 1 to 1 exchanged? http://www.wewiretheworld.blogspot.com/p/led.html
