All compact fluorescent lamps require a slight warm-up time for the electrical current to fully heat the cathodes and reach their full lumen output. When a bare spiral CFL is first switched on, it lights up with approximately 80% of its rated lumens, but it will heat up to its full brightness in about one minute.
Do fluorescent bulbs go bad?

Why do my light bulbs slowly get brighter?
Lamps that get brighter over a timescale of minutes are usually discharge lamps of some sort; fluorescent, CFL, sodium, Mercury, SON etc. They all rely on a discharge through an ionised gas, and it can take time for the temperature and pressure of the gas to build up to the correct working values.
How long do ballasts last?
