6/7 LED Cluster Bulbs


LEDtronics®, Inc. announces a family of sunlight-visible, bayonet-base 6/7 LED cluster lamps as replacement for incandescent T3¼ miniature bulbs whose critical status indication is the determining factor and relamping costs are a major consideration. The LEDtronics LED lamps feature a 90% reduction in power consumption (very low power draw of 0.8-0.91 watts, depending on the LED light color) and directly replace numbers including 6MB, 44, 47, 755 (5/6V) 12MB, 756 (12/14V), 24MB (24V), 313, 757, 1819, 1829 (28V), 48MB (48V), 60MB, 1835 (60V), 120MB and NE51H (120VAC). 

The solid-state design of the BF3126 and BF3127 Series LED lamps renders them impervious to electrical and mechanical shock, vibration, frequent switching and environmental extremes. They boast faster turn-on and reaction time compared to filament lamps, yet provide comparable luminous intensity and pure wavelength light for a more uniform illumination. These miniature bayonet base bulbs are available in the following LED light colors, all sunlight-visible: 470nm Super Blue (InGaN), 525nm Aqua Green (InGaN), 570nm Lime Green (InGaAlP), 595nm Super Yellow (InGaAlP), 612nm Super Orange, 660nm Ultra Red (GaAlAs/GaAlAs), 8000K Cool White (InGaN) and 3000K Warm White (InGaN). 


  • faster turn-on
  • solid-state design
  • impervious to electrical and mechanical shock
