After finding two luminaires that take PAR36 lamps, and finding a 24V and a 36V lamps to fit, it got me interested in the different PAR-type lamps that might be useful for MVs. I ended up digging through a large pile of surplus lamps and found a pair of 150 watt 28V PAR46 lamps as well as a 60W and a few 36V 50W PAR36 forklift lamps.
"GE 4572, PAR46 (5.75" dia), Auto Flood Military, 28V, 150W, 4500CP, 300HR, H=55 deg. V=55 deg., screw terminals" I think I can have some fun with them if I can find luminaires.
After digging through all those lamps, many appearing similar yet having very different beamwidths and wattages, it occurred to me that a chart of PAR-type lamps might be handy when finding the odd lamps at a swap meet. - -to see if they are suitable for one's own needs.
So attached is a file with 53 of these lamps in it of which nineteen are 28V and as many are 12V. I hope the chart covers the most useful types from 5.5 to 75V and from smallish PAR36 spotlamps andlheadlamps to large deuce-headlamp-sized lamps, including some halogen types. There a few odd voltages in there as well. For instance, a 36V lamp makes a great work light, and will never burn out (or burn your hand) at 28V. In any case, a good reference for the box of lamps at the swap meet.
BTW - NAPA 4863 - -as listed in the x-reference on this site, is the deuce headlamp. -but it could not be found on the NAPA site. Maybe I did not look hard enough.
