I have used this brand for some years now, and find them very good.
This one is pearl, has a boyonet fitting, and is equivalent to the old 42W.
It is also dimmable which many of my lights are.
I bought this at Coles, in Inglewood, WA, for $3.87.
Summary
This brand seems to last for ages and is 100% Australian owned.
