Guilt free household downlighting
The current fashion for peppering whole house interiors with low voltage downlights has a couple significant drawbacks, they are extremenly energy inefficient and have a very short lifespan. Most people wrongly presume that because the light fittings are low voltage, that means low energy use. This is not the case. Low voltage simply means that the voltage used at each light fitting has been reduced, this is then wasted as lost heat. Most of the standard downlight globes are 50 watt, only sligtly less than a normal 60 watt incandescent globe. So there is no energy saving there.
So what is the solution if you want guilt free downlighting?. Replace your standard downlight globes with compact fluorescent fittings from a company such as Megaman. Most compact fluroescent globes are only around 11 watts, 80% less than the standard downlight fittings and will have a life up to 10 times longer.
