Flashlight and Lighting Gadgets


When it comes to lighting, this does not seem to be an area that most people tend to give a lot of thought to. Whether it is installing a lighting system for their home, or using a flashlight device, most people are rather content with the first arbitrary model item that comes to hand, and don't really give much consideration to their options.

Studies have shown that if people were to turn off their lights when not using them, and/or switch their current light bulbs to energy saving light bulbs then the could save up to 20% on their annual electricity bill. Energy saving light bulbs are truly remarkable examples of efficiency, they produce the exact same amount of light, but require 80% less of the energy, which has huge implications for cost, as well the effect on the environment. The advantages for the climate chiefly derive from the huge reduction in carbon dioxide that is produced and emitted by light bulbs as they heat up.

Your typical light bulb tends to have a lifespan of 5,000 hours in total; this figure is 8,000 for energy saving light bulbs. I cannot emphasise this enough, when you consider that 80% less of energy is required for an energy saving light bulb and given that it lasts almost double the time as an ordinary light bulb, changing light bulbs does not seem quite a trivial priority anymore.

People are often put off by the higher cost of an energy saving light bulb, whilst saving the world and preventing damage to the climate is all very well, most people are concerned with their budget, and practical day-to-day issues. Energy saving light bulbs is a worthy investment, that will provide massive long-term savings, and of course, as they become more prevalent in the market, the cost of production can be steadily reduced.

The innovative design of the bulbs is truly remarkable; the latest design to hit the market is solar powered lamps. Now that may sound a contradiction in terms, surely lights are used when it is dark, and if it is solar powered, it needs ready access to the sun?

Absolutely! Researchers have designed such lamps to mimic a plant, whilst a plant will gather the sun's rays in the biological process of photosynthesis and then use that as food during the course of the night, so does the solar powered lamp, gather up the sun's rays, and utilises an LED light to emit the light. Simply leave the lamp close to a window so that it has ready access to the sun, and this will allow the solar cell to store the energy.

These lamps are also waterproof, meaning that they can be safely kept outside for maximum sun exposure and have an on/off switch that will toggle not only the LED lighting (thereby conserving the energy of the solar cell) but also the solar cell itself. A truly remarkable engineering design, and don't worry, with a frosted glass design with such lamps, your lamp wont be spoiled by ugly, clunky batteries and the like.
