FP flash bulbs/lights
 

There where some type of flashbulbs that allowed some cameras that have slow sync flash speed to use sync speeds up to 1/500 or 1/1000 seconds. How can you make the difference between an standard Magensium bulb and F.P. one.

The bulb packaging would have a type number including the letters FP, like "FP-26". I don't recall for sure if the bulbs would be marked individually, but I think they would.

Here's a place that lists some types of bulbs:

But can I put such bulbs in every flash unit that can fit them or do i need a special flash unit?

You can use them in any flash unit they fit into. The only important point is that to use them with a short duration focal plane shutter, the camera must have the correct sync timing (M sync). Two things cooperate in this action:
1) the shutter slit opens and starts to travel after a short delay to allow the bulb to reach full brightness
2) the FP bulb maintains full brightness for a longer time than a regular bulb, allowing time for the shutter slit to travel across the whole image

The GE brochure on this site shows the difference between regular and FP bulbs:

I will study more that site.
I have an "Minolta" SRT-101 with FP connector.
But it's strange that I've seen that "Sylvania" was saying for they bulbs that FP comes from something elese.

Sorry, I confused M and FP bulbs.

The Minolta manual shows the difference in shutter speed range on p.31:

If you download the manual, you should leave a small donation to support the site.

I know that site. That's where I found about the F.P. flash bulbs.
I'll make a donation when I will have an bank account or I will put money on my "Pay Pal" acount.
But is the "Philips" FP5B a normal F or M bulb or an F.P. bulb? http://www.flashbulbs.com/Philips_ph-1.htm
I found for sale the FP5 version... probably only for black and white films.

Look again at the Philips page. I think you made a mistake when reading. It says "PF5B", not "FP5B." I think "PF" stands for their trademark "Photo Flux," or "Photo Flash," not "Focal Plane."

The light curve for the PF bulbs is very peaked, not flat-topped like a focal plane bulb.

Also, the FP5 is probably a clear bulb? So it would not be for color film requiring daylight color.

Yes, my bad, it's PF.
So the light curve must be like the one from the 2 diagrams from the low right of this image: http://www.flashbulbs.com/CrPDwnlds/FlashInfoPdf2Sm.gif

That is correct.

But generally speaking, bigger bulbs (not as big as one with E27 screw mount) had more power then small one that didn't had theyr own socket, but in stad 2 wires getting outside (I have about 20 with that wires...).
