OSRAM金属卤化物灯HQI-TS70W/150W/NDL/WDLPOWERBALL/POWERSTAR,双端/单端金属卤化物灯的工作原理与白炽灯完全不同。放电灯两电极之间发生的弧光放电使得放电管内的填充物质发射光线，这种光线是直接由电弧放电产生。与填充物为气体的放电灯(如氙灯)比较，填充物为金属的放电灯需要一定的时间(***多2-3分钟)才能达到***大的光输出，这是由于填充材料完全蒸发需要一定的时间。型号功率Lm直径总长灯丝灯座包装数HQI-TS70/D75W500020114.257RX7s12HQI-TS70/NDL73W550020114.257RX7s12HQI-TS70/WDL75W500020114.257RX7s12HQI-TS150/D150W110002313266RX7s-2412HQI-TS150/NDL150W112502313266RX7s-2412HQI-TS150/WDL150W110002313266RX7s-2412HQI-T250/D250W200002516381.5Fc212HQI-TS250/NDL250W20002516381.5Fc212HQI-TS250/WDL250W220002516381.5Fc212HQI-TS400/NDL400W3500031206103Fc212HQI-TS400/D400W3700031206103Fc212HQI-T70/NDL75W550020114.257RX7s12HQI-T70/WDL75W500020114.257RX7s12HQI-T150/NDL150W112502313266RX7s-2412HQI-T150/WDL150W110002313266RX7s-2412HCI-T70/NDL72W500020114.257RX7s12HCI-TS70/NDL72W550020114.257RX7s12HCI-TS70/WDL72W500020114.257RX7s12HCI-T150/D150W110002313266RX7s-2412HCI-TS150/NDL150W112502313266RX7s-2412HCI-TS150/WDL150W110002313266RX7s-2412HCI-TS250/D250W200002516381.5Fc212HCI-TS250/NDL250W20002516381.5Fc212HCI-TS250/WDL250W220002516381.5Fc212PhilipsCDM-T70W/830CDM-T70W/942CDM-R150W/830CDM-R150W/942OsramHCIT70/WDLHCIT150/NDLHQIR150/WDLHQIR150/NDL===========================POWERSTARHQI-T,管形金属卤化物灯透明，带辅助极HQI-T250/N2502050047.5257137103E4012HQI-BT400/N40036000632811742E4012HQI-BT1000/N10001100001823952523E406透明，需触发器HQI-T250/D25020500472261501E4012HQI-BT400/D42032000632851752E4012HQI-T400/N44042000462731751E4012HQI-T1000/D100080000763402204E406HQI-T2000/D20001800001004302655E404HQI-T2000/N/ESUPER20002400001004302655E404HQI-T2000/N/SN/SUPER20002400001004302655E404HQI-T2000/N/230V2000190000100430265549E404透明，内触发HQI-T2000/D/I2000180000100430265500E404HQI-T2000/N20002000001004302655E404)
