People who do not ventilate their homes properly expose themselves to harmful levels of pollutants, according to experts from the Glasgow School of Art. Specialists at the school’s Mackintosh Environmental Research Unit (MEARU) said modern homes were being built to be airtight. This causes a build-up of harmful chemicals and moisture if householders do not open windows or vents.

LED technology creates a more efficient, less wasteful way of producing light output than lightbulbs of the past though, due to ever-changing technology, some consumers can find it difficult to stay up to date with what LED lighting means for them. For example, many people relate the amount of light being produced from a bulb to the wattage being used, yet the wattage of a light bulb is becoming a redundant measure since a 5w LED bulb can produce the same amount of light as a 50w halogen bulb. We must now re-train ourselves to use lumens as the measure of how much light a bulb is producing. More lumens mean it’s a brighter light; fewer mean it’s a d immer light. For example, to achieve the same light output of a 60w conventional bulb, you will need an LED lamp with around 800-850 lumens. Switching on to LED can offer customers cost savings. LED bulbs are highly efficient and last longer than the average traditional incandescent bulb. That means they create the same amount of light using less electricity and save on replacement costs.
