Compact fluorescent lamps with integrated ballasts were designed as a more energy efficient product that replaced incandescent lamps. Although there was another competing technology in late 70s that could have prospects as energy saving lamps, the small metal hallide lamps, the flourescent lamp won in the end. Flicker, colour variations, slow start and especially long delays on the restart made low power metal hallide lamps as entirely unsuitable. Also, there was the issue of cost and tighter manufacturing tolerances that made metal hallide lamps very expensive compared with incandescent lamps. The research on compact fluorescent lamps was centered on miniaturization of the lamp and integrated ballast while keeping a reasonably moderate efficiency. Tubes could be made slimmer if the flourescent coating could operate at higher temperature and avoid absorbing mercury so development was not entirely straightforward. Development of more powerful green an blue phosphorus than the standard halophosphates was essential, while a good red phosphorusof Yttrium/Vanadium was already available from research on cathode ray tube high efficiency red emitting powders. In the end, cost was extremely important.

While this lamp generally follows the typical progress of flourescent light sources, there is one major feature that was specific to this range. In late 1980s, a compact flourescent lamp was designed, the venerable SL. It was the first product to use a magnetic ballast and starter that were integrated into a rather bulky base. The lamp had a noticeable hum and flicker but it brought major advantages in terms of energy efficiency in replacing typical incandescent lamps. In the 1990s, compact lamps received an improved electronic ballast that improved lamp's efficiency and lifetime, with no visible flicker. This development lead to later mass market popularity of compact fluorescent lamps, as they were more compact and slightly more pleasant to use. Of course, there was also a downside. Philips noticed that lamp replacements at the end of their useful life was not popular due to the typical user mindset so Philips did not bother to create, from that point further, lamps that had separate bases and lamps, reducing user mistakes upon replacement.
