Q1: Will the top heat sink fins accumulate dust? Does excessive dust affect heat dissipation?
A: The fins are vertically designed; natural dust mainly accumulates on the top flat surface with limited dust in the fin gaps. Annual cleaning is recommended (synchronized with PV panel cleaning) using a brush for sweeping, which does not affect normal use.
Q2:Tianyi series 50W replace the 30W metal halide lamp in grid-powered street lights?
A: It can be used as a reference, but not a simple power-to-power comparison. Calculation based on actual road surface illuminance requirements is recommended. Tianyi series 50W At 6m installation height, the road surface illuminance can typically meet or exceed that of the 30W metal halide lamp.
Q3: Does the waterproof breathable valve require regular maintenance?
A: The breathable valve is a maintenance-free design requiring no special maintenance under normal use. If obvious moisture condensation is found inside the lamp body, check if the breathable valve is blocked; rinsing the outside of the valve with clean water will restore normal operation.
