Press Release Body: Date Announced: 31 Oct 2008

Yongsheng LED Lighting (http://www.ledlightsorient.com) announce the launch of high
power LED Street Lights Application Programs. Comparing to High Pressure Sodium
Lamp, it can save more than 70% energy. Besides, it's absolutely green and
environmental protection.
Some of us consider we are in economic crisis. Lower cost can make us stronger in
this economic crisis. 70% energy is not a small cost. I may appreciate to these
products.

Main features are as follow：

1. Revolutionary Photometric Design - The world's first dedicated optical system
(rectangular beam focusing lens). Reasonable control of the light distribution, spot
rectangular bean pattern, and ensure an ideal uniformity of brightness on the road
surface;
2. Unique Integrated Lens and Lampshade Design - Array Lens play a protective and
spot light role, avoid wasteful duplication of light and reduce the loss of light,
also reduce the weight of the product and enable simplified structure;
3. Creative Design of the Radiator and Lamp holder Integration - Fully protect LED
life and heat dissipation requirements, satisfied with the structure and design of
LED Lights fundamentally, with the most distinctive features of LED Lights(see
attached picture);
4. Standard E40, 360-degree Rotation Lamp Holder - It can still rotate after full
tightening the lamp holder arbitrarily, adjust to ensure the best direction face to
the ground;
5. Direct Replacement Light Source Design - Direct replace the existing
high-pressure mercury lamp, high pressure sodium lamp, metal halide lamps, no need
to change the original lamp shell;
6. Intelligent Current Control - Intelligent current control, whatever any deviant
situation, it is able to achieve the precision constant current, ensure the LED can
work under the secure current;
7. No Adverse Glare - Eliminate the glare caused by the adverse ordinary lights
glare and visual fatigue sight interference, improve driving safety, reduce the
incidence of traffic accidents, fully embodies the spirit of "People-oriented
Technology" in this product;
8. No Light Pollution - Light Distribution designed for road lighting, in addition
to illuminate the path and will not illuminate the road outside the region.
Eliminate the interference signal by the residents of the light into the rest room;
9. No High-voltage, No Dust Adsorption - Eliminate the high-voltage adsorb the dust
cause the lampshade become dark, reduce the brightness;
10. No High-temperature, No Aging Yellow Lampshade - Eliminate baking the
traditional lampshade which cause aging yellow, shortened life expectancy and
decrease the brightness;
11. Wide Working Voltage - The brightness and working life will be reduced if the
working voltage change more than 7% for the traditional streetlight, but it will not
influence our LED Streetlight at all;
12. Start Without Delay - Reach the normal brightness and do not have to wait when
switch on, eliminate a long process of starting of the traditional street lights;
13. No Strobe - Eliminate the visual fatigue which caused by the strobe lights of
the traditional street lamps;
14. Impact Resistance, Shock-proof, Without Ultraviolet (UV) and Infrared (IR)
Radiation - No filament and glass frames, avoid break of the traditional lamp,
without harm to the human body;
15. High Color Index, Nice Coloration - To show the true colors and more brighter;
16. Multiple Color Temperature Options - Color temperature to meet the needs of
different occasions, eliminated the low color temperature of the sodium lamp which
cause the hypnotic mood and high color temperature of the mercury lamp which cause
the depressed mood, observers will feel more comfortable;
17. Tremendous Energy Saving - Used the ultra high power, high brightness LED light
source, together with the high power efficiency power supply, which
18. can save energy 50%-80% than the conventional sodium and mercury lamps;
Long Life, Up To 50,000 Hours - (Working for 10 hours a day, can be used for more
than 13 years), is 5-10 times working life than a traditional sodium or mercury
lamp;
19. Green and Environmental Protection - no lead, no mercury, no environmental
pollution;
20. Universal Input Voltage - 85-264VAC full voltage range constant,
constant-current PWM technology, high efficiency, low-heat, high-precision constant
current;
21. No Pollution to Power Network - Power factor≥0.9 , THD≤20%, EMI
apply with the global universal index, reduce the power loss and transmission lines
22. to avoid contamination of the network of high frequency interference;
Work Under Low-voltage and Low-Heat, Safe and Reliable - LED junction temperature
can be controlled under an ideal temperature (TJ<70 ℃ Ta=25 C ambient
temperature);
23. Perfect Combination With Solar Energy - Fully exert the advantage of the LED
work under low voltage and environmental work, according to the local solar energy
resources, electricity and solar power can also be combined. To achieve the best
cost performance and high reliability customers;
24. High Luminous Efficiency - LED luminous efficiency of the existing conditions is
≥ 65lm/w, with the rapid increase LED brightness, when the luminous efficiency
reach 150lm/w, the 400W sodium lamp will be replace by the 100W LED lamp, the
luminous efficiency will reach 300lm/w eventually;
25. Have a number of patents for inventions and utility model patents.

Yongsheng high power LED Street Lights are reformation for the traditional LED
Street Lights. It's actually energy-saving and environmental protection lighting
solutions.
