Aircraft Landing Light - A narrow beam PAR lamp (28 volt) that is used on aircraft and often adopted for PAR64 and PAR46 lamps. They are most commonly 4 lamps wired in series to attain the required voltage of the circuit as . Used . close to 120 volts. ACL lamps have a higher intensity, brightness and color temperature than the standard PAR lamp.
ACL lamps are more expensive than standard PARs and have a sho. Used . rter life.

Fresnel - Fresnels are typically 8-, 6- or 4-inch, referring to the diameter of the lens. This light is named after Augustin-Jean Fresnel who invented the distinctive Fresnel lens which has a 'stepped' appearan. Used . ce instead of the 'full' or 'smooth' appearance of other lenses. The stepped nature of the lens causes a corresponding pattern of circles of light, so Fresnel lenses are usually 'stippled' on. Used . the flat side. This pattern of small bumps helps to break up the light passing into the lens to smooth out its eventual pattern.
Fresnels use a spherical reflector, with the filament of the bulb ...
