* Exceeding maximum ratings may damage the LED and cause potential safety hazards.
* Elevated operating temperatures can be expected to negatively impact the service life (lumen output)
* All data is related to entire assembly. Data reflects statistical mean values. Actual data may differ depending on variances in the
manufacturing process.
* End users need to take into account the lumen depreciation as the temperature rises with various thermal solutions installed.
* It is highly recommended for the user to review the CREE ML-E Series page for additional and most recent technical data at

Note 1: Using continuously under elevated loads (i.e. the application of high temperature/current/voltage or a significant change in
temperature, etc.) may cause this product to significantly decrease in reliability even if the operating conditions are within the
absolute maximum ratings.
Note 2: The thermal resistance from the LED junction to ambient temperature, Rth(j-a), should be kept below 200C/W (all colors) so
that the LED is not exposed to a condition beyond the absolute maximum ratings.
Note 3: The temperature of the LED assembly must be measured at the TB-point according to EN60598-1 in a thermally constant
status with a temperature sensor or a temperature sensitive label.
Hardware (not included)
> Mount with M1.6 Machine Screws.
> 18AWG Maximum Wire Gauge.
> Use only with constant current power supplies.
PCB Fabrication
> Layer Count: 1
> Core Material: 6061-T6 Aluminum
> Single Layer Copper Weight: 1oz
> Solder Mask: White
