What is the difference from A30003 (5600K) and A30009 (6500K)?

A30003 (5600K) corresponds to the daylight film standard. A30004 (6000K) is slightly cooler and brighter (130lm). A30009 (6500K) is the coolest white tone in the range. For CCT systems, A30004 is a frequently chosen cool white pole, combined with a warm white chip such as A30007 (2800K).

Why does the measured brightness of an LED (lumens) differ from the manufacturer's specification?

The luminous flux on the datasheet (e.g. 130 lm) is a typical value that the manufacturer determines under standardized laboratory conditions, at a defined drive current and a fixed junction temperature (usually 25 °C). It is an average, not a guaranteed minimum for every single LED. Deviations mainly come from three sources: Manufacturing tolerance: LEDs are sorted into brightness classes (bins); deviations of a few percent within a bin are common; Operating conditions: Temperature, operating time and the exact current change the light output compared to the lab; Measurement equipment: An integrating sphere and a spectrometer can yield slightly different values than the manufacturer's measurement, depending on calibration and setup. For article A30004, our own measurement is approx. 123 lm compared to the manufacturer's specification of 130 lm, a deviation of roughly 5.4 %. This is within the usual tolerance range and not a defect, but normal practice for LED components.

Why do brightness, color temperature and color rendering of an LED differ from the datasheet values?

Datasheet values describe a reference measurement in the lab, not the individual LED in operation. The most important influences: Junction temperature: The datasheet usually applies at 25 °C. In operation the chip heats up, the luminous flux drops and the chromaticity shifts slightly. Cooling via PCB and heat sink is decisive; Binning: Manufacturers sort LEDs into bins by luminous flux, forward voltage and chromaticity. The typical value is an average, not a minimum guarantee; Color temperature and SDCM: 6000K is a correlated color temperature and therefore an approximation. The scatter of the chromaticity is specified in MacAdam steps (SDCM, standard deviation of color matching). At 1 step, two colors are practically indistinguishable to the eye; from about 3 steps, differences usually become visible in direct comparison; Distance to the Planckian locus (Duv): Two LEDs with the same color temperature can deviate slightly towards green or magenta; CRI and TLCI: Both are calculated from the spectrum and have measurement tolerances. TLCI refers to a reference camera model and can look different depending on the camera; Measurement equipment: An integrating sphere and a spectrometer can yield slightly different values, depending on calibration and setup. For CCT systems or several fixtures side by side, LEDs from the same batch or bin should be used. Channels can be calibrated by measurement if needed.
