Screw-in LED Floodlights
Anonymous Coward writes "This company claims to have the first LED flood lights that you simply screw in as a replacement for your old bulb. enluxled.com are also claiming it's cool enough to handle, more damage resistant, longer lasting (50,000 hours) and only uses 22w to produce twice the light of a 100w bulb." And hideously expensive, but you never have to change them.
Energy saving bulbs we have today?
:D
They only compare them against normal bulbs, and not energy bulbs, wonder why, not nearly as much good marketing maybe
No, I did the math, and it would have to be changed every 5-6 years. 50,000 hours is approximately 2083 days. 2083 days is about 5.7 years. So running one 24/7, and yes, some people seriously do that, I'd have to buy one every 6 years.
I realize how stupid this comment is, but just felt like pointing it out since the story did say, "but you never have to change them.".
You're comparing just the cost of the bulb itsself and the installation, ist your electricity free?
Over here, the LED bulb (assuming the 20W instead of 100W incandescant) would save 50000*(100-20) Wh = 4000kWh at more than 10c each - that's at least $400 saved over the lifespan of a single bulb.
There are such laws. Not everybody follows them. A lot of the halogen bulbs, though, are still under the max.
if you read closely, the claim that the lights put out twice the light output of a 100w flood only applies to the COLORED floodlights.
Which makes sense. A red LED floodlight will be made only with red LEDs, which emit nearly all their light in the red part of the spectrum. a 100w incandescent red floodlight is a regular incandescent with a red filter on the glass, which absorbs most of the light. The implication is that a 100w colored floodlight puts out about 150 lumens. I can believe that.

Also keep in mind that their calculator does not figure the time-value of money into the equation at all. If you plan on doing anything better with your cash than investing in LED lighting products, the break even will NEVER, EVER happen -- at least for a homeowner.
LED bulbs are making a bit more business sense in certain commercial installations where you actually have to pay a human being a minimum feee for an hour or so of labor to go replace a few lightbulbs. Especially in situations where the bulbs are so difficult to reach that it takes a few hours to actually change them and causes an inconveneince for other people while they are being changed -- the fee to change a bulb could easily outstretch the cost of LED lighting. Often in situations where 'expensive' bulb changes happen, they will change all the bulbs at the same time even if they don't need it simply because all the rigging and labor will be there and ready to go.
Awww....give me a break. Have you ever washed clothes by hand? I have. I lived in India, and when I lived in dorms during my engineering days, we had no laundry facilities. "Going home to do the laundry" acquires a totally new dimension then (My parents had a washing machine at home). Try wringing out a pair of jeans to dry on a cold morning at 40 F , and then we'll talk.
