LEDs turn next

There is another new product becoming available, which may make CFLs obsolete.

"LEDs are coming, too, so eventually the LEDs will be available," Gladieux said. "They are just not completely perfected yet, but I think that's the next step in technology. There is some availability. There is a lot of big wattage output still for the light they put out."

Trumbull adds, "We're starting to carry LEDs, but the current problem with those is they are so expensive. Over time the cost will probably come down like it did with compact fluorescents, but the other problem I'm seeing with the LEDs that are currently available is they don't put out enough light."

LEDs as replacement bulbs are currently only available as 40-watt equivalents. They are much more efficient than incandescent and have a life that is 20 times that of an incandescent.

"Most likely LEDs will be the overall winner in a few years to come," Brian Brandes of light bulb manufacturer SATCO Products said. "Right now LEDs are as efficient as CFLs, but their efficiency is predicted to surpass CFLs within the next two years. LEDs have a muchSee our bestleddownlight Lighting displays for a sample of strip lighting applications. longer life — approximately three times or greater than CFLs."

Brandes and Trumbull say LEDs will have the edge over CFLs when it comes to dimming and color.

"The one place where CFLs seem like they aren't quite up to par yet is, there are some who claim they are dimmable, but they are not dimmable in the full range that people are used to in the incandescent," Trumbull said.

Brandes said, "They (LEDs) dim well, have greater color rendition, better light control, and work well in cold temperatures (all a bit challenging with CFLs), but LEDs come at a higher cost. However, as with any new technology, the early introductions have a higher price tag, but prices will drop as volume increases."

"(Some) brighter (CFL) bulbs cause a problem because, for example, if you were comparing a standard 100 watt incandescent bulb to a 100 watt outputted equivalent CFL, the bulb is physically bigger — it's longer," Trumbull said. "So, in certain types of lights some of the enclosed ceiling fixtures you run into a problem because you can't get the compact fluorescent of the light you want into that fixture.

"The same happens with table lamps and floor lamps where they go around the bulb and its held inside the shade,The Magicshine bestcflbulbs bicycle light At 1000 lumens, now brighter and more energy efficient. so there are still some situations where people are stuck.

Laurie Gross, president of Gross Electric, which has a store on Woodville Road, in Northwood, says there is a caveat when it comes to recessed lighting.

"One issue is to identify whether or not the recessed fixture is designed for a general service bulb or a reflector version.Some people are concerned that if they use bestcflbul or flashing lights on their bike they are breaking the law. If it is designed for a general service bulb, then medium screw CFLs will work well," states Gross. "However, if the fixture is designed for a reflector-type bulb, most CFLs that are in reflector shape will provide much less light than incandescent versions."
