LTL-2785Y

Light Bars LTL-2000 Series Features Rectangular light bar. Choices of three bright colors-green/yellow/high efficiency red. Large, bright, uniform light emitting areas. Low power requirement. Excellent ON-OFF contrast. Can be used with panel and legend mount. Easy mounting on P.C. board. Categorized for light output. Yellow and green categorized for dominant wavelength. Description The LTL-2300/2400/2500/2600/2700/2800 series light bars are rectangular light sources designed for a variety of applications where a large bright source of light is required. These light bars are configured in single-in-line and dualin-line packages. The green series devices utilize LED chips which are made from GaP on a transparent GaP substrate. The yellow and high efficiency red series devices utilize LED chips which are made trom GaAsP on a transparent GaP substrate. All devices have white bar.
