- Values based on 350mA and a Thermal Pad temperature of 25 °C.
- Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
- This is the maximum operating current that we recommend for this LED. Higher drive currents may be possible, but will require careful design of a suitable cooling system.
- At the recommended operating current.
- Typical thermal resistance from the LED Junction to the bottom of the module.
- This is the value we recommend you use for determining driver input voltage.

The SinkPAD-II SP-12 Star/O LED module requires careful attention to mounting and cooling to ensure that the junction temperature of the LED is kept well below the maximum rating as specified in the LED documentation published by Lumileds.
For optimal cooling, we recommend that the module be mounted to a suitable finned heat sink (aluminum or copper) that is exposed to open air. The module can be mounted to the heat sink in one of two ways:
Before fastening the module to the heat sink, ensure that the two mating surfaces are perfectly flat and clean in order to maximize heat transfer to the the sink.
Mechanical fasteners are not recommended for this module.
The bottom of the LED module is electrically neutral, so it is not necessary to electrically isolate the base from the cooling surface.
The SP-12-R4 can be ordered in any quantity with quantity discounts available.
If you order more than one piece of this part, pieces may be shipped as part of a v-scored panel.
