- its all about passing along information I never could find anywhere else.
I will report how well these Asian LED bulbs hold up, its all under test now and only time will tell what works well.
About 85% of a my lights used on 1st floor of my home are LED lights.
I put prices on everything so I can remember what I paid.

LEDs under and above cabinets
I have been using these 12vdc LED lights here since October 2009,
these have worked out very well- uses 19.8 watts for all 11 strips - 1.8 watt per strip
I used a 12vdc 1 amp transformer to power this. Yes, it burnt up because it uses 1.6 amps.
I now have a 12vdc 2 amp adapter, this works well, its instant on with no delay
I bought 11 of these 50cm or 20in long with 30 LEDs per strips, they use only 1.8 watts per strip.
thats only 19.8 watts to light the whole kitchen, top and bottom of cabinets - uses 19.8 watts
50cm aluminum light bar with 30pcs
SMD3528,warm white color - DC12V .PDF file
50cm aluminum light bar with 30pcs - price for 11 of above - $8.95 each w/shipping
This was my first project using LED lighting, back in 2007
This is the older system before my kitchen upgrade, I no longer use this lighting system.
I found that the white light looked too white. It didn't work out, the warm lights were the way to go.
Since 01-17-2009 I like the effect these have, very mood setting, a nice warm look - uses .96 watts 80MA @ 12vac/vdc per LED
Works very well under the narrow cabinets in kitchen where the light bars are too long - G4 White LED 12V AC DC
I replaced all my halogen 10 watt bulbs under the cabinets with these
The LED lights are turned on and off by touching a 1/2 metal
bar (seen in picture above) mounted around the edge under of all cabinets.
G4-xHP6 White LED lamp
G4 base bulb with 6 High Power White LEDs
12 Volt AC or DC, again great for a 12vdc PV solar system
77 lumen cool white 7000K
55 lumen at warm white 3100K
120 degree beam pattern
0.9 inch diameter
An electronic touch switch is used to accomplish this. The only way
this touch switch would work properly was by using 12vdc, it got rid
of the ac flicker in the lights and made touch switch work well from long distance.
The draw back with this is it will need 110 vac to make it work, and would not work with a 12vdc PV solar system.
Replaces 50 watt bulb - I bought from e-bay $27.99 ------- EarthLED ZetaLux
I mounted this on my gargage door unit on 05/03/2010,
it comes on every time the gargage has been opened. Works wonderful! - uses 7 watts one bulb
I use two of these LED bulbs below in my ceiling fan, I started using them on 05/30/10 so far they have worked wonderful
they LED lights are not an exact match to the incandescent bulb, they are a little on the cool white side - uses 9 watts one bulb
The new DEFINITY LED bulb in the familiar A19 shape is dimmable and a direct replacement for the most common incandescent bulb
Unlike compact fluorescent lamps (CFLs), the DEFINITY LED bulb contains no mercury, is completely recyclable,
and offers outstanding light quality. In most home applications,
Americans are expected to save $255 in energy cost over the life of the product and the
bulb will pay for itself in less than two years from energy savings.
Home Depots $20 EcoSmart LED light: This is whats inside?
This can be bought at Home Depot
This has been under test since 01/15/2009 every night for 8 hours 12VDC compact 4200k CFL fluorescent light bulb 9W = 80W
Would be a perfect match for a 12vdc PV solar system
Bulb rating: .82A x 12V = 9.4w actual consumption = 80 watts light output or (1120 Lumens)
Bulb will stay lit when power drops down to 6 Volts.
Bulb can be only started at 10-12V DC
Average bulb life: 8,000 run-time hours
I use this 12vdc CFL and with a 12vdc supply/charger battery as a power back-up
this comes on every night from sundown to 12 midnight
This would work extremely well with a PV solar system - uses 8 watts
Since 01-17-2009
I was using this LED in the front bay window it was on 24 hours a day
This is another light that will work well with a 12VDC PV solar system

One 3x1 watt led light to light up the tree and one 1x3 watt led light for front door, that's all
I have been using this since September 15th 2008
The light on the tree is as bright as a 30w haligen,
it shines to the top of the tree, you can't see it in the picture
The LED bulb being used on door is a 4.6 watt LED to give you 45 degree spot illumination
that is comparable to a 35 watt halogen bulb. Its a warm white that
I'm using to light the front door

One of the 3 * 1 bulbs got water into the fixture, bulb was replaced on 06/23/10
One of the 3 * 1 watt led lights quit working it now has a 4 * 1 cool white below on 10/10/10
I'm using 14 MR-16 LED bulbs at 3 watts each, 1 MR-16 LED bulb at 4 watts and 19 wedge leds at .36 watts for a total usage of 55.84 watts.
I was using 526 watts for my yard lights, now I'm only using 55.84 watts.
My cost for electric is about .075 per kilo watt I was paying .31 cents per night for 8 hours and $9.30 per
month I now pay .04 cents per night for 8 hours, only $1.20 per month. I'm saving $8.00 per month
LED's are coming into their own. LED's are over 33% better and power consumption then CFL's( CFL's = 13 watts for 60 watt equivalent,
LED = 8 watts for 60 watt equivalent) I think this is higher, its all about how many Lumens. The life span is also 500% better.
10,000 hour life span for CFL, 50,000 hours for LED or almost 18 years if used for eight hours a day. ... Plus LED's come in different colors
What makes LED's green?
LEDs contain no lead or mercury, which makes them very environmentally friendly.
They also last around ten times longer than halogen lamps and 50 times longer
than incandescent lamps,thereby helping to significantly reduce maintenance costs.
Don't buy the cluster type LED's that is a waste of money, buy the 3 watt LED chip or the
LED light with 3 one watt led chips made by CREE they work well
Since September 15th 2008 - these are working great
The mailbox uses two .36 watt LEDs wedge lights for total power used .72 watts
both are wedge LED lights the top led is a cool white & bottom address is a warm white - uses .36 watts each wedge
Don't be so concerned with lights that are on for 5 to 10 mins a day.
Only change the ones out that are on alot like the living room, kitchen and yard lights.
Since 01-17-2009
These LED bulbs work perfect for the two lights in China Cabinet
total 4 watts being used and they come on every night for 6 + hours.
I'm impressed with these little LED bulbs, they work extremely well - uses 2 watts each

LEDs in cabinets
I removed the wood panels and installed glass in each door
There are 6 blue festoon led bulbs behind each glass door.
Cost is $.01 per to light 24 hours a day for a whole month, I'm using 12 festoon bulbs
My total cost is only $.12 per month
Be careful buying the cheaper festoon bulbs, after only 1 year they burnt out . The replacement
festoon bulbs I now have are 9 leds type instead of 6 led, these are a much better bulb.
There is also a small shade being used to keep the light directed inside the cabinet

The Array LED R30 is a LED high output R30 lamp.
The Array R30 is equivalent up to a 65 watt incandescent bulb but uses up to 80% less energy
and lasts up to 25 times longer.
Each Array bulb will cost much more than its glass and filament 60W incandescent ancestor, but a lifespan of
some 50,000 hours (three years permanently lit, or about 10 years or so of "normal" use) combined
with the electricity savings you'll make, will compensate for the price.
In most cases, the pay back is less than 3 years
Here are case studies of money saved using the Array Led Bulb.
Many Governments have already passed measures to prohibit the sale of incandescent light bulbs.
The aim is to encourage use of more energy efficient lighting alternatives, such as compact fluorescent lamp (CFLs) and LED lamps.
Brazil and Venezuela started to phase incandescent light bulbs out in 2005 and other nations are planning
scheduled phase-outs Australia, Ireland and Switzerland in 2009
Argentina, Italy, Russia and the United Kingdom by 2011
Canada in 2012 the European Union by September 2009 and the U.S. between 2012 and 2014
425 million 60 watt incandescent bulbs are sold in the U.S. every year this makes up 50% of the bulb sales.
Lighting accounts for approximately 30% of the total energy consumption in the US.
Until everyone personally buys their first LED bulb, don't worry about the LED craze being over any time soon, not hardly.
We also have our government mandate that eliminates incandescent bulbs between 2012 to 2014
It isn't until you're in Starbucks and over hear some people talking about LED stocks, that you should be fearful that the
LED craze is coming to an end.
At Lazard Capital, analyst Daniel Amir asserts that the demand for LED-based general lighting products
will grow at better than 30% a year compounded now through 2014.
Daniel has been recognized by Zacks research as - Best on the street - in 2006,
but its not hard to do good in a good market like that of 2006.
