GREAT CONSERVATIONISTS,
PLEASE SHOW ME THE LED LAMPS WITH SOCKETS TO PLUG INTO MY STANDARD TABLE LAMP OR CEILING LAMP AND I'LL BUY SOME.
I HAVEN'T SEEN ONE IN USA YET. OUR CRAZE LATELY HAS BEEN TO TRANSITION TO MINIATURE FLUOROSCENTS.
IF SOME INDIAN HAS THE LEDS IN A SCREW IN SOCKET FOR 110V 60HZ FOR THE STANDARD USA MARKET, AND CAN MARKET IT FOR $2.00 PER LAMP, THERE IS A HUGE MARKET. LET ME HEAR FROM THE WATERWALLAHS.

And suppose you do this way:
Wake up just before dawn and busy yourselves at work/school/whatever-- in 30 minutes.
Have standardized fast-health-snacks while at work.Labour communes organize this Catering
Continue and finish work 2 hours before sunset;
Eat simple health food by romantic bamboo-fuelled kitchen fire. Take the name of God and retire.
Repeat!
You don't need Mallya's Yacht,Tubelights,CFL's,LED's ,Super-thermal-power -Stations, Iraq/Afghanistan---.
Scared?
Don't!
That's the only way forward for India.
Or you collapse.
Bye the way ,how much or what % of Sun's free energy do you use on an average day?
Best

Subject: [WaterWatch] Fw: LEDs can help light up the Indian lifestyle
Dear Colleagues,
Interesting info and comparison between different lighting
gadgets. We wish such info reaches people so that they
can go for energy conservation a the same time reducing
their own electricity bills.
By replacing ulra violet tubelights with CFLs, I could bring down
my monthly electriciy bill from Rs 800 o Rs 275 in three months.
There should be mass movement for promoting lower
consumption gadgets to reduce dependence on grid electricity.
Maharashtra is suffering from a shortage of 4500/5500 MW
power yet the government does not act. To ensure uninterrupted electric supply to Mumbai, it is starving and denyng basic supply
to entire Maharashtra. It has increased minimum power shedding timing from three hours in many Maharashtra regions to four and
half hours while it does not supply electricty in other region to
fourteen hours. Unemployment due to power shedding is
increasing in the smaller towns and in rural areas creating
serious distress and discomfort.
As the government is now busy only on promoting power game,
ciitzens can take up this campaign on a serious basis. Akshay
Prakash was started as many of you are aware on an individual
basis. It has resulted in 1100 Maharashtra villages adopting
power discipline resulting in savingh of 400 MW. Friends
interested in taking up this campaign are welcome.
Best wishes

LEDs can help light up the Indian lifestyle
Jacob Cherian MUMBAI
To achieve 504 lumens
Incandescent : 40 Watts needed(@12.6L/watt)
CFLs : 8.4 watts needed @ 60 L/watt
LEDs : 9.16 watts needed (@55L/Watt)
No. of Lamps needed for 50,000 hours
Incandescent :16.6 Lamps (@3,000 hour life)
CFLs :7.14 lamps (@7,000hour life)
LEDs :1 cluster of LEDs (@50,000 hour life)
A) Cost of Lamps needed for 50,000 hours
Incandescent :Rs 182.60 (@Rs11/bulb)
CFLs :Rs 1071 (@Rs 150/bulb)
LEDs :Rs 916 (@Rs 100 Watt)
Electricity cosnsumed for 50,000 hours
Incandescent :2,000 Kilowatt
CFLs :420 kilowatt
LEDs :458 kilowatt
B) Cost of 50,000 hours needed of electricity
Incandescent :Rs 7,200 (@Rs 3.60/unit)
CFLs :Rs 1,512 (@Rs3.60/unit)
LEDs :Rs 1,648 (@ Rs 3.60/unit)
Total
Incandescent : Rs 7,382.60
CFLs :Rs 2,583
LEDs :Rs 2,564
They are on Mallya's yacht. They may already be in your puja room. They line Subroto Roy's staircase. They're all over the Amby Valley discotheque. We're talking about light-emitting diodes, better known as LEDs. The LED is
slowly, but surely, winging its way into the commercial lighting market on fringes of specialty applications. In a country struggling to come to terms with a power crisis, LEDs' efficiency and durability is gaining recognition
in niche markets. They are now found in architectural highlighting, rural lighting projects, in the average flashlight and home lighting for the energy conservationist who can afford it.
Shyam Sujan, president, Electric Light and Component Manufacturers of India (Elcoma) says the market for mainstream LED lighting is barely a million units a year and growing. This is negligible, compared to the CFL
market at 100m units, which grew at 40% in 2006. He says, "CFL got attention because the government took it up. This is not the case with LEDs. The ministry of power has now decided to contribute to bringing in an MNC to put up a plant in India." While the mass market in India is moving towards compact fluorescent lamps (CFL) from incandescent lamps some enthusiasts are
moving away from CFL to LEDs.
CV Rao, an engineer and a software consultant in Hyderabad, has his entire 4,000 sq ft apartment lit up by LED lamps. His apartment, which otherwise would have consumed 1,000 watts of electricity, now consumes
approximately 200 watts. While he saves on a monthly basis, he does have a huge initial investment. Fitting his apartment with LEDs, five months ago, cost him ten times more than what it would cost him to light it the traditional way. Yet he says, "In a trade off between the cost of
installing LEDs and the damage to environment from using CFL or filament bulbs, I'd much rather go for LEDs as I can afford it."
The return on investing in LED lighting is visible within 3-4 years in a commercial establishment, while it is 5-6 years for a residential setup. For instance, architect and designer, Jimmy Mistry has been using LEDs as
highlights in projects like Vijay Mallya's yacht and the Amby Valley disco.
He replaced halogens with LEDs for this purpose. The illumination, he points out, achieved by a 1 watt LED that equals a 20 watt halogen. And therefore for those who can afford to take a long-view of the situation a switch can
make sense.
Among the first to sniff out these benefits are the auto-components, torchlight and NGO sectors. In the auto-industry, headlights are slowly moving over to LEDs, while tail lamps already have. In the rural-development sector, groups like the Environment Conservation Mission, Green Power India and the Indian Army electrical and mechanical engineers Corps are taking solarpowered and hand-cranked LED lamps to villages that are out of the
reach of a stable electric grid.
These lamps cost anywhere between Rs 800-1,600 and are distributed free of cost. A key factor driving people to LEDs is its expected longevity. The life of these 'bulbs' ranges anywhere between 20,000 hours 100,000 hours the life of traditional bulbs. Comparing power consumption, LEDs consume less than a tenth of what incandescent light bulbs do. Though international
attention is increasingly turning to environmental issues, those little lights, which were mostly used in toys and decorative lighting, are not gaining the attention they deserve.
