Description
This family of T-1 lamps is widely
used in general purpose indicator
applications. Diffusants, tints, and
optical design are balanced to
yield superior light output and
wide viewing angles. Several
intensity choices are available in
each color for increased design
flexibility.

Notes:
1. See Figure 5 (HER/Orange), 10 (Yellow), or 15 (Green/Emerald Green) to establish pulsed operating conditions.
2. For Red, Orange, and Green series derate linearly from 50°C at 0.5 mA/°C. For Yellow series derate linearly from 50°C at 0.2 mA/°C.
3. For Red, Orange, and Green series derate power linearly from 25°C at 1.8 mW/°C. For Yellow series derate power linearly from 50°C at
1.6 mW/°C.
4. The transient peak current is the maximum non-recurring peak current that can be applied to the device without damaging the LED
die and wirebond. It is not recommended that the device be operated at peak currents beyond the peak forward current listed in the
Absolute Maximum Ratings.

Notes:
1. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
2. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the
color of the device.
3. Radiant intensity, Ie, in watts/steradian, may be found from the equation Ie= Iv/ηv, where Iv is the luminous intensity in candelas and η
is the luminous efficacy in lumens/watt.
