A report from the UK government shows that LED lighting, and dedicated LED luminaires in particular, will have the lowest life-cycle impact of all ultra-efficient lighting technologies. The UK governments Department for Environment, Food and Rural Affairs (DEFRA) has published An evidence study assessing the life-cycle sustainability impacts of residential lighting products based on ultra-efficient technologies.
The study can be accessed from the DEFRA website - see under the heading Impacts.
The study is the first to clearly show the life cycle environmental benefits of a shift towards LED lighting, and particularly dedicated LED luminaires. The report assumes that various performance improvements will be achieved by 2014, at which time LED-based products will have less of an Impact across all stages of their life-cycle, including manufacturing, transportation, usage and in the waste stream.
The report analyzes four different ultra-efficient lighting (UEL) technologies: LED lamps with integral ballast (aka replacement lamps) Dedicated LED luminaires Ceramic metal halide lamps T5 linear fluorescent These are compared with established technologies such as compact fluorescent lamps (CFLs) and incandescent Lamps.
The study assumes that the rate of improvement in efficacy and light quality from LEDs seen over recent years will continue over the next five years, taking the efficacy of lamps to over 100 lumens per watt - though improvements beyond this may also be envisaged.
It concludes that efforts to stimulate the developments of acceptable LED lighting solutions would further reduce the impacts from residential lighting, which has already begun with the phase-out of incandescent lamps. In particular, dedicated LED luminaires, because of their design, proven to have The least impact of all lamps.
The research also demonstrates that although the market is not currently ready for domestic application, LED lighting has potential for significant benefits over CFLs, which contain mercury, and have a relatively short lifetime.
