LEDincandescent

Features Direct replacement for less reliable incandescent bulbs Advanced variant operates from 26Vdc full bright and is dimmable Standard variant operates from 6, 12, 15, 24 and 28Vdc MTBF in excess of 80,000 hours 'Cool light' - reduced heat dissipation Benefits Reduced maintenance costs Reliable fit and forget option Reduced power consumption Excellent off-axis viewing Applications Avionic pushbutton switches Mimic panels Caption/warning indicators Further Details The T1 (682 series) midget flanged incandescent replacement indicator lamp features a high intensity single chip LED, which is optically designed to give an excellent spread of illumination. The lamps are available in standard and advanced variants, the advanced version is designed to take PWM dimming input. The integral circuitry of the standard variant has been designed to directly replace 5 - 6, 12, 15, 24 and 28Vdc incandescent bulbs. Circuit configuration for both variants can be either centre contact anode or cathode. The operational life of the LED is in excess of 80,000 hours. They are ideal for a wide range of applications including push button switches, caption/warning indicator switches and annunciator illuminator. The extensive life of the LEDs means that replacement and maintenance costs are greatly reduced.
