Standard Miniature Lamps
Miniature Lamps have advantages and should be considered by the design engineer for those applications requiring higher light output or higher temperature operation than is available from Light Emitting Diodes (LEDs). Another advantage is their broad band spectral emission, which extends from the visible to the infrared.
General Information
These lamps are specified for current, brightness and life at their design voltage. The lamp may be operated at voltages other than design voltage. This variation is called operating voltage. An operating voltage higher than design voltage will result in increased brightness with a decrease in rated life. Rated life may be increased with a decrease in design voltage.
Design current, measured in amps, is the current flowing through the lamp filament when operated at the design voltage. Normal tolerance for design current is (+/-)10%.
Total luminous flux of miniature lamps is measured using an integrating sphere and other instruments and standards with calibration traceable to NIST. Mean Spherical Candle Power (M.S.C.P.) are lumens per steradian and Lumens are units of total luminous flux into the full 4p steradians of solid angle for a sphere.
Standard Miniature Lamps in this section have been aged and selected to a brightness tolerance of (+/-)25%. When required, these lamps may be selected to a closer brightness tolerance of (+/-)15% or (+/-)10%. This selection requires adding AS15 or AS10 to the standard lamp number.

More Information
Rated life as specified in the Standard Miniature Lamp section of this catalog is expressed in terms of hours. Rated life is calculated at design voltage, with alternating current and under ideal laboratory conditions. In actual use, lifetime may be shortened as a result of hostile environments such as shock, vibration, and extreme temperatures. Life may be substantially increased by selecting an operating voltage less than the design voltage. This decrease from design voltage will also result in a cooler filament providing increased resistance to shock and vibration.
Subjecting the lamp to a burn-in period will improve the stability of light output over time. It is possible to do an accelerated burn-in for these lamps by running them for a specified time at a carefully controlled voltage greater than their design voltage. This service can be performed by International Light Technologies for production quantities of any miniature lamps that they sell.
