Light Emitting Diodes (LEDs) are well documented for their energy
efficiency and usage diversity, but their poor colour rendering and
colour temperature has slowed their adoption for domestic use. Expensive
per unit in comparison to traditional light sources, they nonetheless
dominate the research and development labs of some of the world's
leading lighting manufacturers. This research project explores what it
is that has got the lighting industry so excited about this technology
that was discovered almost 90 years ago, whether consumers will share
their enthusiasm and aims to establish the extent to which LEDs have
revolutionised the lighting industry. The author sourced reliable data
from LED manufacturers and energy efficiency regulators, using
lighting-specific magazine articles to ensure that all data used is
current at the time of writing. Once a statistical comparative is
formed, the opinions of lighting industry experts are considered and
compared, and drawn on to form a conclusion.
