Dimensional Diagram
A diagram shows the dimensions of the lamp. The diameter (D) is 50 mm and the height (C) is 54 mm.
Photometric Data
Spectral Power Distribution: A graph displays the spectral power distribution of the light, showing intensity across different wavelengths from 200nm to 800nm. The peak intensity is around 450nm and 550nm, with a broad distribution across the visible spectrum, indicating good color rendering.
Light Distribution Diagram: A polar diagram illustrates the light intensity distribution. The light is concentrated in a narrow beam, with the highest intensity (up to 1000 cd) directly in front of the lamp (0 degrees), decreasing significantly at wider angles.
Lifetime Data
Failure Rate: A graph shows the failure rate of the lamp over time. The failure rate remains at 0% for the first 20,000 hours and gradually increases thereafter, reaching approximately 50% at 40,000 hours and close to 100% by 60,000 hours.
Lumen Maintenance: A graph illustrates lumen maintenance over the lamp's lifetime. The lumen output starts at 100% and gradually decreases. At 40,000 hours, the lumen output is approximately 70% of the initial output, and it continues to decrease to around 60% by 60,000 hours.
