English

Subject field(s)
  • Lamps
  • Photography
DEF

An incandescent filament lamp designed to burn at an appreciably higher temperature (by making the filament carry an appropriately higher current density) than general purpose filament lamps of smaller voltage.

OBS

This increases the light output and colour temperature, but shortens the burning life of the lamp to a few hours.

Domaine(s)
  • Lampes
  • Photographie
DEF

Lampe incandescente à filament conçue pour éclairer à une température nettement supérieure aux lampes à filament courantes dotées d'un faible voltage.

OBS

Une telle puissance a pour effet cependant d'en écourter la vie utile.

OBS

On rencontre aussi le vocable «lampe survoltée» comme équivalent de «photoflood lamp», laquelle est plus spécifiquement une lampe d'un éclairage moyen de 36 lumens par watt employée surtout en photographie.
