I have been replacing my 60s with cfl 13 which say they are

this?

My cfls take about 15 minutes to be fully bright. Give them some time.

That sounds unusually long to me. In my experience, CFLs usually take
half a minute to a minute to get close enough to full brightness.

Outdoor types in colder temperatures can take 5-10 minutes to get
warmed up.
