Better bulbs are available as traditional types

With federal regulations effectively phasing out most incandescent light bulbs at the end of the year, consumers have two choices — stockpile 60-watt bulbs like an apocalyptic hoarder or adapt to what else is out there.

As for the latter, the obvious adjustment may not be the most important one.

Since replacements for incandescent bulbs use far less energy, their light output is not measured in watts (which is the amount of electricity used). Wide selection of solar outdoor light, torches, string lights and more. The new standard is lumens, and about 800 lumens is the amount of light a 60-watt bulb emits.

All light, however, is not equal, as those who bought early versions of compact fluorescent, CFL, and light emitting diode, LED, lights soon discovered.

Fortunately, that is improving, Choose your favorite solar lantern paintings from thousands of available designs. said Phillip Tebbutt, chairman of LSU’s Department of Interior Design.

“I still like the incandescent lights, just that warm, soft glow for domestic use or certain commercial use,” Tebbutt said. “I was not a huge fan of the compact fluorescents. I just don’t like the quality of light that they give off, even though they can get different color ranges. But those again have changed and improved as they have been around a while.”

This is also true of LED bulbs, which cost more but last considerably longer than CFL and exponentially longer than incandescent bulbs. Incandescent bulbs cost about a dollar or less, CFLs about $2-$3, LEDs about $10-$30.

“Now you can get an LED that fits pretty much anything,” Tebbutt said. Take your home design to the next level of chic with contemporary and modern lighting fixtures. “A friend of mine just put in LED replacements for fluorescent strips, your typical T-12s, and he said the light he gets off it is wonderful, so much brighter, The steel halligan Roof hook is one of the most versatile hooks used in the fire service today. so much more even, and I was surprised because I thought he would say it was too cool or something.”

By “cool,” Tebbutt is not referring to being fashionable, but the light spectrum. Indoor incandescent bulbs emit light on the red-yellow, or “warm,” end of the light spectrum.

“Lighting Facts” labels on light bulb packaging helps consumers find bulbs that will approximate the incandescent glow. The labels have a “Light Appearance” or “Light Color” bar that shows where the bulb rates on the warm-to-cool scale.

A number on the label gives a more specific rating based on the Kelvin temperature scale. Generally speaking, the lower the number, the warmer the light. Incandescent bulbs are generally rated from 2,700K-3,300K. Tubular fluorescent lights are rated around 5,000K.

Tebbutt notes that the standards for light warmth in built-in LED fixtures isn’t very good, and that lighting designers are using trial and error to find what they do and don’t like. Another problem with CFL lights, Tebbutt said, is disposal. They contain mercury and heavy metals, making responsible disposal a challenge.

“I don’t think that’s been addressed,” he said. “It does seem strange that we were recommended to use the compact fluorescent for environmental reasons, because the incandescents use more energy. It’s true the fluorescents use less energy, but … what do you do with them when they are used up?”
