If you’re looking to save electricity and lower your electricity costs, start by considering that the adage “you get what you pay for” applies very much to the light bulbs and tubes you use in your home. Here’s an energy-saving tip: more efficient bulbs – like Verilux Energy Star compact fluorescent light bulbs (CFLs) – can cost more to buy than conventional incandescent ones, but they’re so much cheaper to operate that over the life of the bulb, you’ll easily make up that initial cash outlay in lower energy costs.
In fact, while they can cost as much as 10 times as much to buy, a CFL will last 13 times longer than an incandescent (10,000 hours vs. 750 hours), which means you’ll need to buy an additional 12 incandescents while you’re still burning the one CFL. With typical use of about 1,000 hours per year, an incandescent bulb will last nine months while a CFL bulb will last ten years.
And because they’re much less energy-efficient, you’ll spend $84.701 more on electricity to use incandescents than you will the CFL over its 10,000-hour life. Then add that the average household uses 40 light bulbs2. . . .In fact, switching to Verilux Energy Star CFLs could reduce your electricity bill from lighting as much as 75 percent.3 You can calculate for yourself the additional value of skipping the extra shopping trips, ladder climbs, etc., you’ll need to replace those incandescents.
Consider also the quality of the light that’s coming from the bulb. All Verilux productivity lighting products feature Natural Spectrum® illumination that simulates the best qualities of natural daylight to help you see better. This light better stimulates more of the eyes’ photoreceptors, so some of them aren’t working too hard while others have nothing to do – a scenario that causes glare and eyestrain and accelerates fatigue. Also, a relaxed eye has a smaller pupil that can better focus the light, so it’s in a much-improved environment, conducive to increased visual acuity and processing.
So, look beyond the initial price tag and consider what you’ll pay over the life of the bulb. Choose CFLs, and you’ll carry a happier pocketbook and live on a happier planet – because you’ll be saving money and using far less energy to light your world.
1Lifetime energy costs based on: (1) initial cost of $1.00 per 100W incandescent bulb with a lifetime of 750 hours; (2) initial cost of $10.00 per 23W Verilux Energy Star Natural Spectrum light bulb with a lifetime of 10,000 hours; and (3)energy cost of $0.11 per kWh.
