Silicon Transistor are solid-state semiconductor devices with functions such as detection, rectification, amplification, switching, voltage regulation, and signal modulation. The transistor acts as a variable current switch and can control the output current based on the input voltage. Unlike ordinary mechanical switches (such as Relay and switch), transistors use electrical signals to control their opening and closing, and the switching speed can be very fast. The switching speed in the lab can reach more than 100GHz.

Cree said that LM-79 is already an indispensable test for manufacturers in the semiconductor lighting market. TEMPO 24 not only covers the fully certified LM-79 test, but also exceeds all existing test standards including the LM-79. TEMPO 24 helps ensure the production of high-quality, energy-efficient semiconductor lighting products while providing customers with the information they need.
TEMPO 24 offers a more comprehensive LED luminaire test than all current third-party testing organizations. In addition to the LM-79 tests that have been approved for electrical and photometric measurements, the TEMPO 24 test also includes color discrimination and color point evaluation, chemical compatibility, and TM-21 life prediction. TEMPO 24 provides comprehensive testing of LED designs and provides customers with realistic luminaire performance assessments to help customers promote and highlight their products. Each TEMPO service provides customers with an accurate and easy-to-understand TEMPO report that includes all test results and related performance data.
TEMPO24's certification with the National Laboratory NVLAP marks the operation of the laboratory in compliance with US National Laboratory NVLAP regulatory requirements and technical requirements, including quality systems, personnel, residential and environmental, test and calibration methods, equipment, measurement tracking, sampling , testing and calibration of items, testing and calibration reports. Cree Lab also meets the requirements of the American National Standards Institute (ANSI) and the National Institute of Standards and Technology (NIST). 
Cree launches the world's most comprehensive LED lighting test service
Cree announced the addition of TEMPO 24 to expand its comprehensive testing of LED luminaires. The new TEMPO (thermal, electrical, mechanical, photometric, optical) 24 service combines the IES LM-79-08 photometric test with industry-leading omnidirectional LED performance testing to ensure the overall system design of LED luminaires And quality. The Corer Durham Technology Center has passed the NVLAP certification of the National Laboratory, which will enable Cree to further help LED lighting manufacturers solve design difficulties and accelerate the launch of high-quality products.
