Hi Mo, it may be that someone here will know the answer but it may help if you tell us what piece of equipment uses these short peak lamps

I haven't heard of these and I have been doing darkroom work for nearly 10 years.

As far as I know short peak is a term used to describe a type of flashbulb meaning that the maximum light output of the bulb occurs for a shorter length of time than a long peak, long peak flashbulbs have a higher output given that the shutter is open long enough to utilise it, follow links below for more info.

Hi Mike ,how ar u? When I read the leica M5 instruction book they said that "X synchro contact for electronic- flash and short-peak lamps" I am confused with this , I don't know what is the meaning of short-peak lamp here.

Can I consider that short-peak is a flash bulb?

Yes, X synchro is generally used for electronic flash but can be used with short peak flash bulbs, it is explained better than I can here :-

Good, it looks like Vannanan has answered the question for you, Mo. I must admit I never think of flash bulbs these days but there were quite common until probably the mid to late 1970s which is quite recently at my age.
