Notes :
(1) Seoul Semiconductor maintains a tolerance of 7% on Intensity and power measurements.
(2) Correlated Color Temperature is derived from the CIE 1931 Chromaticity diagram.
Color coordinate : 0.005, CCT 5% tolerance.
(3) Tolerance is 2.0 on CRI measurements, 0.1 on VF measurements.
(4) Thermal resistance is junction to Solder.
(5) IFP conditions with pulse width ≤10ms and duty cycle ≤10%
(6) It is recommended to use it in the condition that the reliability is secured within the Max value.
• Calculated performance values are for reference only.
• All measurements were made under the standardized environment of Seoul Semiconductor.
