QDo LED lights really have 50,000 hours lifespan?
A 50,000 or longer lifespan is a theory based on laboratory tests. However, because actual working environments differ from lab conditions, the practical lifespan is typically around 30,000 hours. It can reach 50,000 hours if high-quality materials are used.
QWhy do different suppliers have different brightness for the same power?
Different chips or different brightness versions of the same chip will result in different light outputs. Even with the same chip, there may be slight differences. Please distinguish between the brightness of individual LEDs and the final lamp fixture.
QWhat is Colour Temperature?
Kelvin (K) is used to measure light "temperature". For example, warmer light (lower Kelvin) is often used in public areas to promote relaxation, while cooler light (higher Kelvin) is used to enhance concentration in offices.
QWhat is CRI?
CRI (Color Rendering Index) is a figure that indicates how accurately a light source reveals the colors of objects. Higher CRI values generally result in higher costs.
QWhat is PF and Efficiency?
PF (Power Factor) and Efficiency measure the electrical performance of the driver. Higher PF and efficiency ratings indicate better performance and usually come with a higher cost.
QCan these lights be used in extreme weather?
Yes, with an IP66 rating, these lights are designed to withstand dust and powerful water jets, making them suitable for outdoor applications like stadiums and squares.
