Bulbs in a New Light

You can stop putting off buying fluorescent bulbs—they look better than ever.

Once upon a time, fluorescent lighting was reserved for basements and garages. Over the years, technology has improved the lights, making them brighter, whiter and less conspicuous.

This painting (right) by Michigan artist Jan Upp, hanging in Country Lines’ offices, was illuminated by a 50-watt halogen flood lamp (bottom) until it was replaced with a 16-watt Sylvania fluorescent flood lamp (top).

Halogen flood light The halogen lamp is more focused, but the fluorescent light does a much better job of brightening the corner where the picture hangs. We got these bulbs at Lowe’s. You can find similar bulbs at Meijer’s, Home Depot, Target, Menard’s, and ACE and Tru-Value hardware stores. For best results, look for lamps that are classed as “bright white” or “daylight.” Fluorescent flood lamps encase the familiar twisty bulb in a flood lamp shell.

Sure, they cost more, but they also save a ton of money over their useful lifetime. A 16-watt fluorescent bulb that replaces a 65-watt incandescent light will save up to $39 in electricity costs over the course of its 8,000-hour life – that’s four times longer than the old bulb would last. So, over the lifespan of the fluorescent bulb, you would have bought four $1 incandescent bulbs, meaning the extra investment of $3 for the fluorescent light returned $36 in savings. Not a bad investment. If you burn your light for 5.5 hours a day for four years, you’ll save $9 a year until the lamp burns out. And that’s just one light. Multiply your savings by 10 or 20 lights and you can see the savings add up.

Of course, if you are using less electricity, that means less electricity has to be generated to meet your demands. If every house in the state converts most of their lighting to fluorescents, the demand on Michigan utilities will drop dramatically, delaying the need to build new power plants. And that’s one of the goals of the state’s 21st Century Electric Energy Plan.

And here’s a bonus: Since fluorescent lights generate less heat than incandescent bulbs, switching to fluorescents will reduce the amount of air conditioning needed in summer. (Don’t argue that incandescent bulbs will help with heat in the winter; there are much cheaper ways to heat your home.)

  1. A question for one of your electrical engineers regarding compact fluorescent bulbs.

    I connected a 23W bulb through a .1 ohm resistor and hooked up an oscilloscope across the resistor to measure the current the bulb is drawing. As advertised, the RMS current X 122V RMS came out to about 23 Watts. However, the current waveform was highly non-proportional to the voltage. The bulb drew current during only 1/4 of each half cycle with very steep on/off slopes and other ripple. I also looked at a 4 foot, double 40W bulb fluorescent fixture, and it was not nearly as bad.

    If everyone converts over to these compact fluorescent bulbs, will there be harmonic noise or power factor problems? Or is the total effect small compared to other polluters like computer power supplies, induction motors, etc.

    Thanks,
    Just curious.
