Unverified别为省电盲目选半导体：半导体因制冷效率低需长时间持续通电，实际长期耗电未必低于间歇启停的压缩机，且大温差工况下半导体功耗反而更高75% similarUnverified弱电箱内空间狭小散热差时不建议放大功率PoE或万兆交换机，长期高温会导致降速和寿命缩短，应选低功耗无风扇机型或加装散热75% similarUnverified最高亮度档位发热明显且续航短，长时间作业需切换到中低亮度维持稳定输出74% similarUnverified选购时注意驱动电源是否内置及散热，劣质恒流驱动是筒灯频闪和早坏的主因，独立外置驱动便于后期更换、寿命更长；深防眩配深杯散热更佳74% similarUnverified灯泡越亮不代表加热越好——部分廉价款用高瓦数灯泡强行提温，会导致机身外壳过热烫手，应关注是否标注表面温度控制或使用双层隔热结构74% similar
