Brightgreen D900 Curve LED Lights

Apparently there are new building requirements limiting the power consumption for lighting to 5 watt per sqm, so for your average 50 watt downlight this equates to 10 sqm of roof area or spaced every 3.3 m. I don't know how this will look or what your typical spacing is, but I've been looking into energy efficient downlights & it seems the only viable option is the Brightgreen D900 curve. link

They're priced ~ $120 each, so it could be a costly upgrade from normal downlights, but they may be a better alternative than having to change lighting designs (i.e. downlight configuration) to comply with regulations.
