text: -The cost of OLEDs is still high and each unit produces less lumens than a normal LED
text: The cost per watt of output power of an LED for illumination is relatively high, but dropping rapidly with further advances of the technology – mainly by increasing the output power of the LED chips.
text: As the cost per watt is still relatively high, and the output power is limited, such applications started in areas such as traffic lights and stop lights for cars, where moderate optical powers are sufficient, the long lifetime is particularly important, and the efficiency advantage over a filtered incandescent lamp is very large.
