4.4W Candelabra warm white 21 SMD LED bulb replace 40W

$15.95

Latest product on the market. This Candelabra shape light bulb uses 21 pieces of high efficiency SMD (Surface Mount Device) LEDs to produce as much light as 100 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 bulb produces a 2800K warm white color similar to the light produced by common household incandescent light bulbs

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) total: $526	$15 in replacement bulbs (5 bulbs) $105 in electricity (0.2/KWh) total: $120	$0 in replacement bulb (still working) $51 in electricity (0.2/KWh) Total: $51
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.
