I have tried Philips ambiance 15W R80 CFL from bunnings, which is pathetic in terms of warming up, it would look like a 15W incandescent bulb for a good few minutes before finally lights up, and it's horrible to wait the lounge to light up when you have visitors. The tornado series are better but they don't produce R80, I use them in light fittings?wherever?I can.
I have also tried GE 15W R80 CFL from mitre 10, they lights up quicker than Philips, but the GE extends too much out of the well, some of the light are wasted on the ceiling, and amplifies any imperfections there.
What's your experience? Do you have any recommendations? P.S. both model cost me about $12 each.
