Paying for electronics
Nevertheless, there is no escaping it: Energy-efficient bulbs can cost up to ten times more than traditional filament bulbs. While the initial cost of energy-efficient bulbs is much higher than conventional bulbs, according to the Energy Saving Trust, energy-saving bulbs endure up to 10 times more than a regular bulb and can provide savings between £3 and £6 yearly in energy costs (for a 100W bulb) - a total maximum saving of £60 over the life span of the bulb in decreased power bills and alternative costs.
Understandably, the much higher bulb price is not just because the manufacturer has padded an exorbitant profit margin for the sake of it. The bulbs themselves include a very complex range of components in the base which converts the power from the light socket into the low-wattage light without blowing the bulb or producing heat.
Phased household roll-out
If you own a big property, installing it with low-energy bulbs all at once will definitely dent your wallet. The most practical and economical way to do it is to wait for a filament bulb to expire and then replace with a low-power bulb.
Although many homeowners begin as skeptical users of low-power bulbs, many soon discover that their bills decrease and the bulbs work longer than filament bulbs.
Speaking from my own experience, five years ago, I replaced four 60W filament bulbs in a fixture of wall lights with four 11W compact fluorescents which cost £5 each. Not only did I reduce the power consumption from a collective 240W to 44W (an 81% reduction), but the original compact fluorescents still function well and have not been replaced so far, whereas the old tungsten bulbs blew each month on the average for the price of £1 a bulb.
Multiplying £12 of replacement filament bulbs yearly by 5 years, gives £60. Subtracting the £20 price of energy-saving bulbs amounts to a saving of £40 over 5 years in bulbs alone, not taking considering yet the money saved through lesser power use.
So, power-saving bulbs really work and are not a scam. Yes, they cost more to purchase than conventional filament bulbs; but they do endure longer and lessen power usage.
