No go for me.the light equivalent to a 20-watt incandescent
60W+ equivalent, or what's the point?
Besides, years ago when I went CFL, I went to daylight color. I believe they are 5700K spectrum.
I was at Lowes the other day and was taken taken aback at how many options I had to choose between light bulbs. There are now a ton of LED options and the prices have significantly dropped.
I haven't looked for any in a while. That LED bulb I bought some time back is still working fantastic. What are they down to in price? Ar they at $5 or less yet?
The LED's I bet stay pretty cool. It's the electronics that drives them that gets hot. Your stage lighting LED's will have these controls at the dimmer controls. Probably in a decent size box with a fan.
LED's are Light Emitting DIODES. A diode has a constant breakdown voltage. If your voltage is less, it will not light. If it is more, it will burn out instantly. No room for error, therefore a current control of some sort is necessary for them to maintain their voltage under changing conditions. I'm sure the circuitry will get better as compe ion increases. I am frankly surprised they get as hot as they do. I understand it though. Maybe I should say disappointed they didn't use a better circuitry design.
The link I previously posted has this picture:
Those cooling fins do get hot.
Very nice.
Data Sheet: SWITCH100
I wonder if they will make them in ~5700K color?
I've had LED bulbs on my front entrance and drive way for 5 years, same bulbs. They do just fine. I don't need to be able to tan under them.
LOL...
I just prefer a daylight color instead of cool white.
If it goes for the rumored price (~25.00) I will try one out and may end up with a house full. Imagine you can run two in a fixture that's rated for the power dissipation of only 2 60W incandescent bulbs. Even just one, 1600 Lumens in an otherwise rated for 40 (think bench grinder or lathe lighting) would be sweet.
Time to check out Lowes, Home depot, etc. At that price, I will pick some up too.
Cree Reaches LED Industry Milestone with 200 Lumen-Per-Watt LED
http://www.cree.com/news-and-events/...mber/mkr-intro
At only 185 degrees.
" enable the next generation of performance in our indoor directional luminaires.”
luminaires? really, ing luminaires?
Hahawwwgh...Hahawwwgh! *French Laugh*
Shazbot...
You mean Illuminatis?
well, people have winter tires that they change out, why can't they have winter light bulbs that they change out.
They would be super efficient, save you electricity and heating.
Actually, 185f is less than what an incandescent bulb operates at.
Smarty McSmarty pants!
yeah, but incandescents aren't efficiently producing that heat.
Intelligent McIntelligenty pants!
Ok, I didn't know that was the case, so I guess this is bigger news than I thought!
Stupid McPoopy head.
FYI.
For some years now, he have hundreds of these in our equipment. Not to save electricity, but because when automation equipment indicator lamps burn out, it is difficult on the operators at times. It can also be a daily routine to replace the incandescents when you use so many lamps prone to burning out.
Future dims for incandescent bulb, despite Texas’ unique law
By David Barer
One Texas lawmaker looked up and saw beauty in the array of glowing incandescent bulbs hanging from the state House of Representatives' chandelier. Another lawmaker flipped on the lights in a University of Texas bathroom and couldn’t tell if the compact fluorescent bulbs were broken or if he was going blind.
Those experiences, and a helping of small-government philosophy (), spurred the creation of a state law counteracting federal legislation to phase out inefficient bulbs. The law allows Texans to manufacture incandescent bulbs, create jobs and keep traditional incandescent bulbs on store shelves.
To date, not a single in-state bulb manufacturer has materialized, incandescent bulb selection in hardware stores is dwindling, and the sweeping federal law on light bulb efficiency continues to cause confusion among retailers while skipping regulation of some widely used energy-sucking bulbs.
“The most disappointing thing to me is that we haven’t found anyone willing to put in a plant and make them,” said state Rep. George Lavender, R-Texarkana, an author of the bill, which took effect Jan. 1, 2012.
Other states have written similar legislation, but Texas has been the only state to pass it into law.
The light bulb hubbub began in 2007 when Congress passed the Energy Independence and Security Act, a 300-plus-page law that, among other things, set tougher energy-efficiency standards that traditional incandescent bulbs don’t meet. Standards that went into effect a year ago, for instance, require manufacturers to produce bulbs that provide as much light as the traditional 100-watt bulb but use only 72 watts of electricity. Compact fluorescent bulbs and LED light bulbs easily meet the new standards.
That federal legislation spurred Lavender, Reps. Marva Beck, R-Centerville, Bryan Hughes, R-Mineola, Cindy Burkett, R-Mesquite, and more than two dozen others to kick back at federal meddling and the stretching of the interstate commerce clause, Hughes said.
“It was about more than light bulbs,” Hughes said. “I also don’t like compact fluorescent bulbs,” he added.
The federal legislation succeeded in exposing customers to the benefits of higher-efficiency bulbs, but the phase-out process has been confusing, said Kelly McGary, manager of The Light Bulb Shop in North Austin.
McGary sells just about every type of light bulb used in Austin through her small shop on Burnet Road, from new LED Christmas lights to old-school sodium bulbs and 1,500-watt, high-intensity bulbs that look like glass footballs.
She’s not sure how much longer the remaining incandescent bulbs in her shop will be available — maybe a year, she speculated. The conversion process has been muddy, she said.
Manufacture and importation of traditional 100-watt incandescent bulbs ceased on Jan. 1, 2012, but retailers can still sell them as long as the bulbs were made or imported prior to that date. The new standards began to be applied to 75-watt bulbs on Monday and will be extended to 60- and 40-watt bulbs on Dec. 31, 2013, said Anne Guertin, spokeswoman for light bulb manufacturer Osram Sylvania, in an email.
While residential customers are changing their light bulbs, many streets in Texas are still illuminated by large, energy-guzzling bulbs not regulated by the federal act.
Parking lots and street lamps use high-wattage bulbs that can burn 10 or 12 hours straight, but residential customers burning 100-watt bulbs for maybe eight hours a day were targeted, McGary said.
“I don’t think those are the big energy suckers,” McGary said.
Austin Energy is slowly replacing the city’s 70,000 streetlights with more efficient LED lights. The utility is also updating the remote timing system and improving fixture covers so light shines down, not out. None of the changes were required by legislation, Austin Energy spokesman Ed Clark said.
“We are doing it through attrition,” Clark said.
At a Home Depot near Interstate 35 and Ben White Boulevard, store manager Sean McMullen has watched the once marginal LED and compact fluorescent bulbs become the majority of bulbs on display. Prices have dropped, and manufacturers have tweaked the bulbs to make the light quality more pleasing. Customers are getting into the mindset of conservation, McMullen said.
“When I introduced the bill, the LEDs were $50 a piece; that’s just not affordable,” Lavender said. “They are coming down. I bought some LEDs the other day for $15. They will probably be worth it.”

TX Repug legislators are ing stupid, as are the Texans who elect them, repeatedly.
