Flourescent lamps were an evolution of clear mercury vapour lamps. Development followed two avenues to increase efficiency, low pressure mercury vapour discharge and high pressure mercury discharge. High pressure mercury discharge created more useful light but the same deficit of no red and orange light was present so the light was still unsatisfactory. Low pressure mercury discharge is very efficient but not in outputting visible light, it is on UV-light emission. This UV-light is useless if it cannot be converted to visible light. | |||
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. | |||
As all compact fluorescent lamps were ultimately an economy prospect to replace consumer's incandescent lamps, price was the most the important factor. This lamp's design was slightly changed over the years as tubes having a lower diameter were used and this brought a modest improvement in light maintenance, useful life and efficiency. | |||
The compact fluorescent lamp market was increasing up until the early 2000s, when most incandescent fixtures were replaced, and it slowly declined with the transition towards led lighting. The worldwide incandescent bulb ban had a major impact in increasing sales but in a slightly different way: users simply purchased lower quality bulbs or cheaper integrated compact flourescent lamps, meaning that there was little incentive in the design improvement except manufacturing cost savings. | |||
