Hi just to share with you guys. Recently i bought 30nos of LED downlight for a total price of 1575.00( 7W LED downlight Taiwan ) for my new renovated house. Understand from my elecronic engineer friend is that you got to compare the lux level, LED driver, and which brand of LED they use. In the market, there are brand as follow Cree , Nichia , Osram , edison and philips. We cannot base on the spec to buy the LED lighting. My house LED spec as following Dimension size: diameter 100mm x depth 25mm tilable 0~45 degree Beaming Angle : 60 degrees color : Netural White 4000K White Finishes Hope this info help when you guys are sourcing for good LED lighting.
