Good service to the UK from these guys.





I agree that LEDs are the future rather than CFL. Look at where=20
LEDs have come in such a short space of time.=20

Even now you can get a MR16 GX5.3 LED bulb that consumes just 4.5W=20
produces 375 Lumen across a 120degree beam in warm white. It is=20
also fully dimmable, the downside is it is cutting edge technology=20
and costs =A322.50.

lumen-p-1577.html

In a years time I guess this will be around =A310 and two-years=20
around <=A35.00.

I also think that lighting will change, instead of a single high=20
wattage bulb in the centre of the room we will have many low-
wattage LEDs around the room lighting for tasks.

Just my thoughts,

Paul
