L14 - Energy Saving Light Globe
Implementing this symbol means the business/company is gradually retrofitting the CFL energy-efficient light globes with the latest eco light globes.
The trend back to the old way of lighting follows the discovery that the CFL compact fluorescent lamp is an environmental failure. Some countries are fazing them out and placing bans on their sale largely due to the high energy required for the manufacturing process and mainly due to the high Led content. These bulbs are non-recyclable and produce more Co2 emissions in their manufacturing process than what the light globe is able to save, even more, wastage occurs when their promised five-year life expectancy is not reached. The CF lamp requires plastics and lead in its manufacturing process, all of which is harmful in landfill and incineration plants if not disposed of correctly.
The old incandescent light bulb is a simple construction of glass, a small amount of thin sheet metal, and thin filament, all 100% safe and recyclable and not generating toxins. The new generation bulb is more efficient, lasts a lot longer than the old type. It has also been improved with the use of a man-made alloy that has a better material temperature resistance than tungsten, resulting in increased brightness. A 42w new type bulb can replace a conventional 60w light globe and provide the same brightness. Basically, any light bulb wattage you purchase with this new technology bulb will allow you to save 30% in energy. The bulb is quite cheap, it can be dimmed and has a two-year life expectancy, which is calculated over a 24-hour use. So, if it is used eight hours a day, it could be expected to last around six years. Since new technologies are offering us many options to save energy we can afford to give the CFL a miss for the good of our ecosystem. The new incandescent eco globe costs less, is less prone to breakage, and lasts for a long period of time. LED (low emission diode) is an even better energy-saving option. It offers 95% energy savings compared to the old incandescent light globe (go to symbol No. M14 to read more). And for fluorescent tube lighting, go to symbol No. M10 - an extra 5% savings can be made from the conventional fluorescent tube lights.
Example: One new energy-saving light globe causes much less pollution due to no content of lead and plastic and electronic components inside the energy-saving CFL (compact fluorescent lamp) E.g. With 60 W equivalent replacement with the fragile CFL 11 W to the more robust new dimmable Eco energy saver globe recently released which does not produce or use highly toxic substances when manufactured or when disposed of. Slightly more costly to run with greater long-term benefits, environmentally.
