Thermal Management

The Saber Z5 must be operated in a manner that will ensure that the junction temperature of the LEDs are kept well below the maximum ratings as specified in the LED datasheet. A heat sink must always be used when operating this module. The size of the heat sink will depend on the ambient temperature and the current that is used to power the LEDs. Bench testing that we have conducted with a SZ-05 module with all LEDs powered at 700mA in an open air environment and an ambient temperature of 25°C has indicated that a heat sink with a thermal rating of 10 C°/W or lower should be adequate. However, you will need to perform your own testing and analysis to determine if this size of heat sink will be suitable for your application.

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. This module is not designed to be fastened with screws.

The bottom of the LED module is electrically neutral, so it is not necessary to electrically isolate the base from the cooling surface.

Optic Compatibility

The Saber Z5 has been specifically designed to accommodate any Carclo 20mm optic that can be mounted into the Carclo 20mm Pegged Foot Optic Holder. You will find a complete list of 100% compatible optics here.

We currently do not carry these optics, however the Saber Z5 is also compatible with:

Additional Information

If you order more than one piece of this part, pieces may be shipped as part of a routed panel that is v-scored so that each carrier tab can be separated from the panel.

Binned LEDsDo you need LEDs with a specific flux, color or forward voltage? Order this part in 1,000 piece increments and we will build it using LEDs from the same bin. We can also provide specific bin numbers. Contact us for availability.
