Returned that 13W "No Frills" spiral, 3000K CFL this arvo.
Staffer grumpy - "oh, you've opened the packet ..... "
Got replacement and tried it out.
Works better than any CFL previously owned by me.
Light output exceeds that of a standard 60 watt pearl lamp, as measured with DSE lux meter.
Colour quality is very similar to pearl lamp.
Lights up immediately it is energised.
So far - so good.
