An important LED lighting fixture information is the Ta rating. Ta, or ‘rated ambient operating temperature’, is the temperature at which a luminaire can be operated while still maintaining all safety-relevant parameters.
This specification is relevant in critical or harsh environments. If a luminaire with Ta 25° is going to be installed where average temperature is 45° C, the 20°C difference will have a significant negative impact on the estimated life of the product.
We have a specific high temperature chamber in our UL certified laboratories to test our luminaires at high temperatures. Every new luminaire gets tested and certified to illuminated and beautify even the most unforgiving regions in the world.
