Description
The 5 volt and 12 volt series
lamps contain an integral current
limiting resistor in series with the
LED. This allows the lamp to be
driven from a 5 volt/12 volt
source without an external
current limiter. The red LEDs are
made from GaAsP on a GaAs
substrate. The High Efficiency
Red and Yellow devices use
GaAsP on a GaP substrate.
The green devices use GaP on a
GaP substrate. The diffused lamps
provide a wide off-axis viewing
angle.
The T-13/4 lamps are provided
with sturdy leads suitable for wire
wrap applications. The T-13/4
lamps may be front panel
mounted by using the HLMP-0103
clip and ring.

Notes:
4. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the
color of the device.
5. Radiant intensity, Ie, in watts/steradian, may be found from the equation Ie = lV/ηV, where lV is the luminous intensity in candelas and
ηV is the luminous efficacy in lumens/Watt.
