Notes for Table 6:

1. Parts are tested in pulsed conditions, T

c = 25°C. Pulse width is 10ms.

2. Voltage minimum and maximum are provided for reference only and are not a guarantee of performance.

3. Bridgelux maintains a tester tolerance of ± 0.10V on forward voltage measurements.

4. Typical coefficient of forward voltage tolerance is ± 0.1mV for nominal current.

5. Thermal resistance values are based from test data of a 3000K 80 CRI product.

6. Thermal resistance value was calculated using total electrical input power; optical power was not subtracted from input power. The thermal interface

material used during testing is not included in the thermal resistance value.

7. V

f min hot and max cold values are provided as reference only and are not guaranteed by test. These values are provided to aid in driver design and

selection over the operating range of the product.

8. This product has been designed and manufactured per IEC 62031:2018. This product has passed dielectric withstand voltage testing at 1160 V. The work-

ing voltage designated for the insulation is 80V d.c. The maximum allowable voltage across the array must be determined in the end product application.
