Need some advise on tcl/pll bulbs

I was wondering if theres a difference in light output or anywhere else I should be aware of. As far as I can tell they fit the same socket and are of same length.
Philips have the PL-L and Secret Jardin the TC-L. Any advise please?

Just google the model number of each bulb and look at the lumens and colour temp (k).

Agreed... google will be of major assistance to you.
