This morning I saw an operating Crompton LED light at Haymans, and several from LEDlux at Beacon Lighting. The Crompton light was on display next to other downlights in a room in which the other lights could be turned off, so I could see its colour and brightness. At Beacon, the LEDlux was tucked away amongst many other downlights in a bright room, so it was hard to determine its colour and brightness.
The prices were significantly different too. The Crompton light is over $175ea, and the LEDlux is normally about $100ea. The Crompton light comes with a lifetime guarantee.
The Brightgreen downlight, which I haven't seen in operation, is $125-$130 from Hotbeam Direct, an online supplier.
At present I am thinking that we should put LED lights in our main living area, and compact fluorescent ones in the rear verandah.
Matt has arranged for me to see one of his other projects tomorrow evening, which has LED lighting, so I can judge the brightness and colour.
