Illumination depends on the Quality/grade of materials used in making the CFL's. Say within Philips 3 ranges are there for the same wattage and different brightness. if you look at the brightness of the high end Tornado series CFL's, its really awesome & unbeatable.
As per my knowledge in India, Only Philips and OSRAM (Siemens) have their own R&D and manufactures as per their specified standards. Rest of the brands like EverReady, Bajaj, Oreva...etc simply imports from Chinese third party manufacturers with their name labelled.
Also length of the tubes makes difference in spreading the light uniformly inside an area. Hence we shouldn't compare CFL tubes directly w.r.to a Tube light. These are meant for replacing the incandescent Bulbs. Lengthy tubes spreads brightness in more balanced way. if you want to compare CFL Tube Brightness w.r.t to the Tube light, within Philips brand, there is a series called Bonsai having around 1.75 ft length comes with 36W 4 Pin CFL Long tubes, Its brightness is too good compared to any conventional Tube light.
