Our brightest PAR38 LED lamp!
Latest product on the market. This PAR38 light bulb uses 42 pieces of
high efficiency 0.3W SMD (Surface Mount Device) LEDs to produce as much light as
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 65 lumens per watt, which is
about 8X more efficient as incandescent bulbs and 1.5x 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
LED bulb produces a 2800K warm white color similar to incandescent light bulbs.
It's also available in other light colors. Red, Blue, Green and Yellow are
custom order only. It will take about 2 weeks to make these special colors.
This PAR38 light bulb can be installed by
anyone into any common E26 medium screw socket(the most common socket in the US
and Canada). Due to the aluminum heat sink, this lamp is rather heavy (about 2.8
lbs.). Please check the size of your fixture to see if this PAR38 can fit before
you order. The height of this lamp is 5.31" and the max diameter is 4.57". Please switch off the power when you install!
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
||electron excited mercury vapor emits UV, which is absorbed by
phosphor and re-emit as visible light
||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
||short, 1000~2000 hours
|Cost to acquire
||around $1 (for a 40W bulb)
||around $3 (for a 9W CFL bulb that's equivalent to
||around $17 (for a 4.4W SMD LED bulb equivalent to 40W
|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
$51 in electricity (0.2/KWh)
|Total carbon emission over 20 years* (8 hrs/day)
||3130 pounds of Carbon Dioxide for a single
||704 pounds of Carbon Dioxide
||344 pounds of Carbon Dioxide
||danger of burning skin when hot and may cause fire in
||highly toxic mercury vapor!
||None, completely safe. won't burn fingers when
||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
||Fragile, sensitive to water and uneven temperature
||Fragile, sensitive to voltage fluctuations and
||rugged and robust. Suited for use under extreme
|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?
||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)

released into atmosphere per every KWh electricity generated. This figure might
drop as we switch to renewable energy.

****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!
