"PHOTOFLUX" FLASHBULBS  
  The modern camera-owner is making ever-increasing use of flashbulbs.

Philips "Photoflux" bulbs are the ideal light sources for exposures of fast-moving subjects or candid shots. They are indispensable for both indoor and outdoor photography - when there is little or no daylight or, in bright weather, to diminish the sharp contrast between the sun-lit areas and dark shadows. "Photoflux" bulbs make every camera-owner independent of time, place, and weather. With this never-failing aid he can be sure that every shot turns out a winner.
BASELESS TYPES

Technical developments have led to the manufacture of a series of small baseless flashbulbs of a high luminous intensity.
Type AG3B is available with a blue coating carefully matched to the colour characteristics of daylight-type colour films but it can be used equally well for black-and-white photography.
In case they are required for particular reasons, AG1 and AG1B are still available.

Other types of small baseless flashbulbs, the PF1B and PF5B, are specially designed for PF-type flashguns.
These blue "Photoflux" flashbulbs which possess the same excellent qualities as the bulb described above, are intended for use with both daylight colour and black-and-white materials.
