Lamp Comparison and Construction
Lamps for Ellipsoidal Spotlights
A problem is encountered with some ellipsoidal spotlight luminaires due to the fact that a portion of
the reflected beam of light is directed onto the cap of the lamp designed for Fresnel fittings. This
leads to overheating of the cap and seal which may result in premature lamp failure.
GE have therefore designed lamps intended for use in ellipsoidal spotlights where the size of the cap
has been reduced and the neck length correspondingly increased, thus removing the critical seal
area from the reflected radiation and ensuring that optimum lamp life is obtained.
Linear and ‘U’ Lamps - for Studio Lighting 3200K
Whilst a comprehensive selection of lamps for spotlight fittings is important to the lighting director,
of almost equal importance is a range suitable for the many different fittings now on the market
which use tungsten halogen lamps of tubular construction. GE believe their range gives a wide
choice and is unmatched in performance and reliability.
