What are the sources of high temperatures in outdoor server racks
One of the most significant issues is uneven airflow, where certain areas of the room—often referred to as “hotspots”—experience higher temperatures due to poor ventilation or improper equipment placement. Outdoor server rack cooling requires selecting the right system to manage heat while maintaining enclosure protection. What Are the Cooling Options for Outdoor Server Racks?Modern servers generate substantial heat during normal operation, and this thermal output only increases as you add more equipment to your racks. Without proper cooling management, even the most robust server hardware will eventually succumb to heat-related failures. Higher temperatures can impact equipment reliability. Industry standards, such as ASHRAE guidelines, recommend maintaining temperatures between 18°C–27°C (64°F–81°F) to balance performance and energy efficiency.

What is the normal value for light decay in a light module
The acceptable light decay range for LED lighting products before reaching the end of life is between 50% – 60%. LED light decay refers to the gradual reduction in luminous flux (brightness) of an LED over time, which is the primary factor determining its effective lifespan. Unlike traditional bulbs that fail suddenly, LEDs typically "die" by dimming until their light output becomes unusable. Lumen Depreciation – the steady decline in total lumen output. For instance, we often hear about LED street lights with L70>100000hrs, indicating that after 100,000 hours of use, the. Thank you for your attention!Light decay refers to the light source due to a long working temperature exceeding the limit value and the light intensity to restore the initial value of irreversible damage phenomenon called light decay.
