TLDR
A simple adjuster based on the sensor reading was developed and tested to one small room with two Light Emitting Diode (LED) and can provide optimized light intensity for the surrounding and reduces the electrical power consumption during daytime.Abstract:
High demand of electrical power receives challenging feedback due to the lack of natural resources and high impact of the global warming. This paper describes one applicable method to optimize the electrical power consumption using Light Dependent Resistor (LDR) sensor. A simple adjuster based on the sensor reading was developed and tested to one small room with two Light Emitting Diode (LED). Two LDR sensors to measure and analyze the surroundings light intensity were allocated for one LED bulb. The LDR sensors interface with each other, and the necessary intensity required by the bulb will be calculated and the bulbs will provide the required lumen for the surrounding/workspace. This system is tested during the day time. The output would affected by surroundings light sources. Hence, the LED bulbs light intensity will be reduced causing a directly proportional effect to the power consumption. This system can provide optimized light intensity for the surrounding and reduces the electrical power consumption during daytime.read more

Light's labour's lost
TL;DR: A broad range of policy measures to stimulate efficient lighting are described in this article, which suggests new ways these could be strengthened to prevent light's labour from being lost, and suggests that the same amount of light from electric lamps now costs only £2! But today's low-cost illumination still has a dark side.
