1. What's a low power LED? How to distinguish between a low power LED and a high power LED?
If the power of each chip is > 0.5W and its working current is > 100mA,
the light-emitting diode is called a high power LED. Vice versa, if the
power of each chip is < 0.5W(usually ≤0.5W) and its working current is
≦ 100mA, the light-emitting diode is called a low power LED. The chip
power of Sunyeah LED lights is only 0.06W, and its working current is
just 20mA.
2. What's a high power LED bulb and a low power LED bulb?
A high power LED bulb refers to a light which is made from high power
LEDs (the power of each LED is > 0.5W). Vice versa, a low power LED
light is a light which is made from low power LEDs (the power of each
LED is < 0.5W).
3. Does the lifetime of a LED Light Bulb shorten by frequent on/off switches?
Unlike the fluorescent bulbs, lifespan of LED Lamps is NOT influenced
by frequent switching.
4. What is the lifetime of a LED bulb?
When properly installed and well ventilated, LED bulbs will very
rarely burnout. However, the brightness of the LED light fades over time, so
LED bulb's life is measured by 2 characteristics - how much will it fade
after 1,000 hours of exploitation, and when will the brightness will reach 70% of the initial value.
Quality LED bulbs are rated at less than 3% light output decrease for
the first 1,000 hours, and 30,000 to 50,000 hours for the 70% decrease,
which is the standard for commercial lighting applications.
Again, compared to traditional light sources, LED bulbs are superior
regarding lifetime.
5. Does the housing color of LED bulb can be changed?
Now, the housing color of LED bulb is available with blue and grey. We
do can change the housing color as the customers’ wish with a quantity
base.
6. Are input voltage of LED lights are limited to AC 100V-240V?
No, The range of input voltage depend on the LED driver we use. So we
can apply various LED drivers to change the input voltage. We
will try our best to satisfy our customers'demand.
7. Do I have to replace LED diodes?
An LED does not burn out like a standard light, so individual diodes do not need to be replaced. Instead, the diodes gradually produce lower output levels over a very long period of time. If one LED fails, it does not produce a complete fixture outage.
