Normal Arc Voltages and Other Figures for Specific Lamps
Now for these figures - arc voltage in normal operation, arc voltage minimum during warmup, and starting voltage. Note that with the exception of d2 type automotive headlight lamps, the only lamps covered below are the usual general lighting purpose HID lamps.
ARC VOLTAGE IN NORMAL OPERATION:
Mercury and metal halide, 50 watt: 95 volts.
Mercury and metal halide, 100 watt: 115 volts.
Mercury and metal halide, 175-400 watt: 135-140 volts.
Mercury 1000 watt H34: 135-140 volts.
1000W mercury H36 and 1000W metal halide: around 220 volts.
Note that 175 to 400 watt mercury lamps will work in metal halide ballasts, but the reverse is often not true. Metal halide ballasts under 175 watts will operate mercury lamps OK except the high starting voltage might be hard on mercury lamps if attempting to restart them hot less than 2 minutes after a shutdown.
35 watt automotive headlight xenon metal halide: approx. 80-90 volts.
High pressure sodium, most models 35 to 100 watts: Nominally 55 volts but varies with age and condition from 45 to 85 volts.
High pressure sodium, most models 150, 200, 250, and 400 watts other than mercury retrofit: Nominally 100 volts but varies with age and condition from 80 to 170, sometimes 180 volts.
High pressure sodium, mercury retrofit 150-360 watts: Nominally 130 volts but varies with age and condition from 100 to 175, sometimes 180 volts.
Note that mercury retrofit sodium lamps will be overpowered when their voltage is high if the ballast is a CW or CWA type or other type with a capacitor in series with the lamp, or with almost any metal halide ballast.
MINIMUM VOLTAGE ACROSS THE LAMP IN EARLY WARMUP:
Mercury and metal halide 70 watts or less: 11 volts.
Mercury and metal halide 100-125 watts: 12 volts.
Mercury and metal halide 175-400 watts: 13 volts.
Mercury and metal halide over 400 watts: 14 volts, maybe 16 for the higher voltage (not H34) mercury lamp.
High pressure sodium 100 watts or less: 11-13 volts.
High pressure sodium 150-400 watts, most models: 12-15 volts.
High pressure sodium 1000 watts: 15-18 volts.
35 watt automotive headlight xenon-metal halide: Typically in the 20's of volts, but I heard allow for 16 volts.
PEAK VOLTAGE NECESSARY FOR STARTING:
Mercury 400 watts or less and the H34 1000 watt mercury: 250 volts, and 220 usually works.
Metal halide 175-400 watts: 500 volts, 450 usually works.
Metal halide 1000 watts or more: 600 volts?
Metal halide under 175 watts and other pulse start models: At least 1500, possibly as much as 2500 volts.
High pressure sodium 35-100 watts: 2500 volts!
High pressure sodium 150-1000 watts: 4000 volts!
High pressure sodium mercury retrofit 150-360 watts: 300 volts.
Automotive 35W xenon metal halide: 7-10 kilovolts, 12-15 kilovolts for hot restrike, 18 to maybe even 20 kilovolts for truly reliable in all cases hot restrike.
OPEN CIRCUIT OUTPUT VOLTAGE of ballast, besides peak of starting pulses:
Mercury 400 watts or less as well as H34 1000W mercury: 180, preferably 200 volts RMS, maybe 220 sustained at least a couple milliseconds with substantial current.
Metal halide 35/39 to 400 watts: May need to be as high as 280 volts RMS with peaks possibly 450-500 volts sustained at least a millisecond or two with substantial current. Maybe a little less for lamps 100 watts or less.
1000W or higher metal halide: probably about 400 volts RMS AC with 525 volts sustained a couple milliseconds with substantial current.
High pressure sodium 35-100 watts, most models: 110 volts RMS AC.
High pressure sodium 150-400 watts, most models: 220 volts RMS AC.
High pressure sodium 1000 watts: 400 volts AC.
35 watt automotive xenon metal halide: over 300 volts with substantial current for cold start, 400 maybe 450 volts with substantial current for hot restart.
