energy saving lamp price in bangladesh – Unique DIY Colorful Cup Figure Energy Saving Pro
Now here’s a shining ideaa lamp that saves you maintenance and helps the environment! It lasts 10 period longer than a suitable electric lamp and uses 80 percent less energy. If you care just about tackling global warming, lamps in the same way as this are a good area to start. During its lifetime, a typical energy-saving lamp will stop virtually one ton of carbon dioxide from entering the declare and pay for itself many period over. in view of that it’s fine for your pocket and nice to the Earth as well. There are two quite rotate kinds: CFLs (compact fluorescent lamps) and LED (light-emitting-diode) lamps. What’s the difference together with them, how attain they work, and which is best? Let’s acknowledge a closer look!
You often hear people tell that lamps in imitation of this pay for themselves quite quickly, but is that really true? Let’s crunch the numbers and locate out!
Suppose you buy an warm lamp rated at 100 watts and it lasts for 1000 hours. In its lifetime, it will use 0.1 kilowatts (100 watts) 1000 hours = 100 kilowatt hours, which is equivalent to 100 units of electricity or 360 megajoules. If you’re in the USA, electricity might cost you 1520 cents per kilowatt hour, making the sum lifetime electricity cost in the region of $1520. (If you’re in the UK, electricity would cost you probably 1520p per unit, making the total lifetime cost of electricity 1520.) A quick look in relation to online reveals that you could purchase a packet of 10 energy-saving lamps for that price. consequently it would acknowledge single-handedly 100 hours’ worth of electricity to purchase one equivalent, energy-saving lamp. For the sake of easy math, let’s tell an energy-saving lamp equivalent to an old-style 100 watt lamp uses 20 watts and lasts for 10,000 hours (so it will use five become old less electricity and cost deserted a fifth as much to run). For every 1000 hours that it runs, it will keep you 80 units of electricity. Ten lamps executive for 1000 hours will keep you 800 units of electricity or on the order of $120160. In further words, switching to low-energy lamps is unquestionably a no-brainer: they easily pay for themselves.
Should you wait till your shining lamps end practicing before varying over? No, amend them straight away: there is no benefit at every to keeping them. What roughly switching from CFLs to LEDs? That’s a slightly oscillate case. Although LEDs are more efficient than CFLs, the difference is smaller and it’s probably bigger to allow your CFLs wear out naturally back replacing them (unless you particularly favor the instant brightness of LEDs).
