ADVANTAGES of coursertech

Coursertech
Others
Solar Panel
Poly, conversion efficiency can be up to 17%
Lower than 16%
Battery
Lead-acid battery of free maintenance
Usually not
LED light
LED chip
American Bridgelux120~130 lm/w,
100,000 hrs life
80~90 lm/w
Heat-radiator
stretch formed aluminum alloy 38°C
die-casting aluminum over
60°C
Reflector
3 times reflection,Light angel:140°

Light angel:110°
Power Driver
Full power and half power energy-saving mode

No
Light power dimmable
Fixed
It’s dusk to dawn working mode
Not that
PWM mode to charge the battery: 20~30% higher
conversion efficiency,
4~5% conversion efficiency in cloudy days

Can not work
in cloudy days
Constant current and power driver are integrated,
put it in the pole,
decreases the maintenance fee

Don’t have this function
High maintenance fee
Result

60W light can replace 250W High-Sodium street lamp;
366 days normal lighting

at least 110W to replace
250W HPS




How to choose one better led street light?
Don’t believe you eyes, but
temeprature

. The lights of different core-tech can cause different Luminous Decay. Our CORE-TECH is the key to solve the problem on optical loss of white light emitting diode (LED).
As is known to all, alluminum alloy is the best choice of heat dissipation.
If use die-casting alluminum, light body temperature will keep more than 60°C.
But,
our light body which is also the heat radiator made of stretch formed alluminum alloy will keep the
temeprature
only

38°C
, which will directly lower light decay, and prolong the lifespan of LEDs.

When using other led lights ,after 300~500 hours of operation the luminous flux of LEDs is 70% of initial levels.But
after 10 years of operation the luminous flux of our LEDs is about 90% of initial levels.

That is to say, after 3~5 hrs of operation ,which lamp body is 60°C is bad lamp.
