How can one get energy efficient? Is it by just reducing our daily energy consumption? No, in that way we are compromising with the service. One can grow energy efficient if we make use of improved technology that can give us the same output but with less power input. We can grow energy efficient by choosing the right kind of lamps. An energy efficient lamp can cut down the utility bills drastically. The advanced and sophisticated technology used in manufacturing these lamps will render it bright at a lower power consumption rate.
The standard bulbs and CFLs (compact fluorescent lamps) are found in the market within a range of 20 Watts to 125 Watts. Higher the wattage consumption, brighter would be the bulb. So if you are thinking of replacing your present bulbs with energy efficient lamps, first you need to check their wattage consumption and the brightness produced by it. Lumen intensity or lux can give you the measure of the brightness of your bulb. Energy efficiency is best achieved when you can bring down the wattage consumption to 20% of your present consumption. But apart from that 50% and 70% consumption rate of your present consumption can also be termed as energy efficient. So when you are looking for the right lamp then calculate the amount of energy reduction you desire and then find the lamp with the same intensity as you are using now.
EU (European Union), Hong Kong and many other regions have framed effective energy efficiency policies. Voluntary and mandatory Energy Efficiency Label standard has been introduced as a result of these policies. This standard would help consumers understand the energy consumption and efficiency concepts better and help them take right decisions. The energy efficient appliances are labeled on the basis of grades. Energy efficiency policies under EU have divided energy efficient appliances into 2 categories starting from A to G. The grade A is given to the appliance which is most energy efficient while grade G is received by the least efficient appliance. Under these policies you can also find directions on the lumen intensity of the lamp. So, you should try to go with branded companies that have received labels from trusted authorities, to be sure of your selection of energy efficient lamps.
You should check the life expectancy of the energy efficient lamps (in years) before purchasing it. Calculate your utility bill that will be generated at the end of those years and add it to the price of the lamp. Now sum up the cost of your standard lamp and the utility bill generated by the standard lamp at the end of those years. The former figure should be less than the latter. If you do not find so, then the amount of money you are paying to buy an energy efficient lamp is not worth the life expectancy it has to offer.
For any good energy efficient lamp the color temperatures are given as follows. At a temperature of 2700K warm white color, at 400K cool white color and at 6500K temperature day white color will be produced. You can compare the temperature with these figures while selecting the lamp. So by checking the above mentioned factors, one can definitely make a good choice of buying energy efficient lamps.
