Toshiba, Panasonic, Sharp, Philips, Lemnis Pharox LED
Bulbs and other comparative tests Comparative Testing LED
bulb
Company development and production of LED bulbs (LED bulb
lamp), as a reference on hand several international brands
LED bulbs, specifically brand is Philips, Panasonic,
Toshiba, Sharp, Lemnis Pharox so. Then compare their test,
specific test LED bulbs luminous flux and luminous
efficiency, temperature rise. Here are some personal sense
of values and test data, only for reference!
Appearance
and production process
The following are sections of the LED light bulb picture,
brand and model
Pharox lemnis LED Bulbs appearance and good craftsmanship,
with glass shade.
PHILIPS LED Bulbs good appearance and production technology,
can not see obvious defects, glass lamp shade.
XQ-lite LED Bulbs rough exterior, glass lamp shade.
TOSHIBA ECORE LED Bulbs appearance and good craftsmanship,
using PC plastic lampshade, this is the test of LED bulbs
only use plastic lampshade.
SHARP LED Bulbs good appearance and production technology,
glass lamp shade, but I personally do not like appearance.
Panasonic LED Bulbs good appearance and production
technology, glass lamp shade, maybe it is too simple
packaging, I got the sample, the glass shade has a small
fracture.
Two LED Bulbs foreign officials and the production process
is rather poor, with glass shade.
Packaging:
Pharox lemnis with paper tube packaging, good protection
against light bulb.
PHILIPS use blister packaging
XQ-lite with box packaging, a protective pad frame.
TOSHIBA ECORE carton packaging with no protection mat frame,
use only plastic bags to package LED bulb lights, the use of
plastic shade, it dares to do so.
SHARP using carton packaging, protective cushion frame. I
think the Sharp LED bulb lamp packaging is the most
reliable, of course, Pharox lemnis is also very good.
Panasonic used carton packaging, corrugated boxes inside the
protection ring to do is probably get the samples are
cracked, personally think that the packaging of Panasonic
LED bulb is not reliable.
More than personal opinion, do not do reference! Or take a
look at the actual facts and figures.
Test data:
The following table shows our measured luminous flux and
luminous efficiency, test time for each LED light bulb in
the integrating sphere in an hour, the concrete into the
initial luminous flux and power consumption, light up
one-third of Zhong Shiguang flux and power, light and a half
hours of luminous flux and power consumption, light up one
hour luminous flux and power consumption. All tests are
completed, the initial 24 hours after the cooling effect of
light intensity matching tests.

Can see that the big brands luminous efficiency is relatively high,
usually in the 60-80LM / W, the Japanese brand of light-efficient,
LED bulbs Philips low only 47LM / W, puzzling. Deficiency of small
brands flux serious, not as ordinary luminous efficiency
energy-saving lamps. Need to be reminded that the Panasonic LDA8D-A1
/ D of PF0.93, which is why we test PF value of the trigger point,
we were not the test, the chance to see this light bulb in the PF
more than 0.9, so the other PF value of LED light bulbs, also made
marked.

We can see from the table, the measured efficiency incandescent
light 8-10LM / W. Energy-saving lamp 44-60LM / W. Comparison of
energy-saving lamps, a good energy-saving LED Bulbs can be 25%,
taking into account the perspective and point LED lighting and
better, the actual energy savings would be greater than 30%. But the
worse of the LED bulb type fluorescent lamp is simply not as good as
saving energy-saving lamps.
I know RC Buck, do not use lamp, LED bulb emitting efficiency can be
more than 100LM / W, but the light quality will be reduced, there
will be strobe. The reliability of its safety will be greatly
reduced, life is not high, hard to meet safety regulations, large
power capacitor with no alternative. Therefore, the power LED Bulbs
mainstream or the use of isolation constant current power supply,
safe and reliable.

The long term, using the LED light bulb is
more economical. For example Spiral Energy Saving Lamp
PHILIPS 5W unit USD3.10, the same XineLam XEL-A40 4W Price
USD14.50, which is 6 times the life of the former. 5W energy
saving lamp is equivalent to 6. Price USD18.60, at least
save USD4.10, this does not include the power of 25%, about
RMB6.20. The question is, who would buy an expensive LED
Bulbs do? Who knows after 10 years what the world is like.
LED Bulbs still have a chance, in the kitchen, walked,
toilet, corridor and other venues frequent switching light
bulbs, especially the use of sound and light control switch
automatically corridor. LED bulb lamp is the latest
opportunity. In these places, looking to replace the near
energy-saving lamps, incandescent you really intend to go
back to it?
LED Backlight advertising system - more than
the world's most efficient energy-saving fluorescent tubes more than
50%, Including the LED drive power consumption, luminous efficiency
of more than 88LM / W.
