Latest product on the market. This MR11 light lamp uses
10 pieces of high efficiency SMD (Surface Mount Device) LEDs to produce as much light as
50 pieces of common top view LEDs. Due to it's surface mount design, the heat dissipation is more efficient and that translate into more power output and longer life. At its peak efficiency, it produces over 70 lumens per watt, which is about 10X more efficient as incandescent bulbs and 2~3x more efficient than a compact fluorescent bulb! This is the ultimate power saving light bulb! It also lasts over 50,000 hours. If you keep it on 8 hours a day, 365 days a year, it won't burn out in 17 years! Please refer to the household lighting technology comparison table for the benefit of switching to LED lighting
*This LED lamp produces a RED light. Unlike
incandescent/halogen/fluorescent colored lamps, which use colored glass to
filter the light, LEDs can be made to emit light in a particular wavelength
band, thus are more efficient.
*Colored LED products are all custom order. It
may take up to 30 days to ship. If you need a large quantity(over 50), we can
offer a deep discount.
*This is currently our brightest MR11 LED lamp.
We will get some 4W high power MR11 lamp soon but the price will be around
$20~25 each. The light output is 280 lumens for warm white and 310 lumens for
cool white. The ETA is March 2011. If you are interested in the 4W high power
MR11 LED lamp, please email
firstname.lastname@example.org for details
and pre-order information.
Comparison of common household lighting technology:
| ||Incandescent light bulbs||Fluorescent tubes and compact fluorescent light bulbs||LED light bulbs|
|light emission principle||high temperature tungsten filament emits visible light along with infrared(heat) lightwaves||electron excited mercury vapor emits UV, which is absorbed by phosphor and re-emit as visible light||Electrolumninescence|
|Efficiency||Very low, only 3%~8% energy converted to light. most wasted as heat||higher, between 10%~20% energy converted to light. The rest wasted as heat||Highest, 20%~45% energy converted to light|
|Lifespan||short, 1000~2000 hours||10000 hours||50000~100000 hours|
|Cost to acquire||around $1 (for a 40W bulb)||around $3 (for a 9W CFL bulb that's equivalent to 40W incandescent)||around $17 (for a 4.4W SMD LED bulb equivalent to 40W incandescent)|
|Cost to maintain over 20 year period (8 hrs/day)||$59 in replacement bulbs (59 bulbs)|
$467 in electricity (0.2/KWh)
|$15 in replacement bulbs (5 bulbs)|
$105 in electricity (0.2/KWh)
|$0 in replacement bulb (still working)|
$51 in electricity (0.2/KWh)
|Total carbon emission over 20 years* (8 hrs/day)||3130 pounds of Carbon Dioxide for a single light bulb||704 pounds of Carbon Dioxide||344 pounds of Carbon Dioxide|
|Safety||danger of burning skin when hot and may cause fire in household||highly toxic mercury vapor!||None, completely safe. won't burn fingers when touched. Nontoxic|
|Environmental impact||lots of burnt out bulbs become garbage, difficult to recycle. Lots of wasted electricity= more carbon emmision||Mercury leak. Special handling and recycle required||Very little. You only need to replace it twice or 3 times in your lifetime. Nontoxic. Highest efficiency means less wasted energy and less carbon emmissions|
|Sturdiness||Fragile, sensitive to water and uneven temperature||Fragile, sensitive to voltage fluctuations and frequent on/off||rugged and robust. Suited for use under extreme conditions.|
|Instant on & Flicker||Instant on, flicker free||takes 5 to 10 minutes to reach peak output, may flicker nad cause eye strain and headache||Instant on, flicker free|
|Easy to find?||Everywhere||Everywhere||Hard to find in your local stores, but you can always order from us. We offer best price and quality, as well as fast and even free shipping(when you order $50 or more)|
*It's estimated currently in the US there's 1.34lb of CO2 released into atmosphere per every KWh electricity generated. This figure might drop as we switch to renewable energy.
|Socket:||G4 bi-pin 12V DC (most common MR-11 type socket)|
|Equivalent Incandescent bulb wattage||
10 pieces of SMD, Red light|
|Usage:||Down light, spot light|
|Size:||1.0" H x 1.37" Dia.|
****Please be aware that many stores sell LED light bulbs that claim to replace 40W or even 60W light bulbs. You need to look into detailed specs and see what's the total lumen output because that's the only thing matters. Don't be fooled by the number of LEDs in the light bulb. Some cheaper LED bulb uses 60 or even 80 LEDs yet only put out less than 200 lumens, while other professional LED bulbs use only a few high power LEDs and put out 500 or even 1000 lumens. The wattage of the LED bulbs are misleading as well. We once found a big chain store selling a 4W LED light bulb made by GE, yet in the fine print it can only product 100 lumens. At 25 lumens/Watt, it's not even as efficient as a compact fluorescent light bulb that costs 5 times less. So please find out what's the total lumen output of the LED product before you buy!
