Which outcome dramatically shortens LED array lifespan when constant-current drivers fail to compensate for thermally-induced voltage changes?

💡 Explanation

Thermal mismatch leads to current hogging, meaning hotter LEDs draw more current exacerbating their heat; because positive feedback dominates, the Thermal runaway mechanism begins, resulting in extreme junction temperatures and degradation; therefore, lifespan decreases rather than efficacy or chromaticity changes.
