Help to ID lamp « on: January 16, 2020, 02:20:11 PM » Author: Edmund Ironside
???Greetings sirs and madams! I need some help to ID a lamp that i do not yet own. I have been promised it but i cant figure out what type of lamp it is based on the pictures ive been shown. The person handling it does not know anything of lamps and can not help me to ID it. Id like to know what typ it is so i can make preparations before i get it and start to read up on it. Im posting two pictures hoping anyone know what type of lamp it is.

Could it be some form of photo flash lamp?

Where would a flash bulb this size would have been used, it is a huge bulb. What kind of gear does these run on? Some kind of capacitor discharge or HV pulse?

If it is, it’ll be for commercial photography studio’s, or it could also be a strobe used in tv or film making?

UPDATE! It is a stroboscope lamp, and it is now safe in my colletion. It is a Philip's made lamp. 1953 vintage, so quite old. Made in Holland. It is a Philips Type 57900 P/06, cant find any references to it in the Philips catalouges on Lamptech. Anyone have any ideas or info? It is quite large, with a big arc-tube. How would one test this bulb without highly specialised equipment? A big capacitor?

Works on normal discharge lamps, don't know about this one though.

Take my advice be very careful trying to light certain lamps unless you really know the gear is correct, better off just keep the lamp in collection be a pity to blow it.BTW the value of lamps is going up the whole time and as I have said better then money in the bank.

Ill follow your advise Migette. Do you know anything about the lamp? Do you have any good sources for vintage Philips catalouges?
