2. This datasheet section presents the Characteristics of the OSRAM GH CSSRM6.24 device, measured under the conditions of IF​=700 mA and TJ​=25 ∘C. In terms of optical performance, the device has a typical peak wavelength (λpeak​) of 660 nm, while the centroid wavelength (λcentroid​) ranges from a minimum of 646 nm to a maximum of 666 nm, with a typical value of 657 nm at IF​=700 mA. The dominant wavelength (λdom​) is 640 nm (typical) under the same forward current, and the spectral bandwidth (Δλ) at 50% relative maximum intensity is 25 nm (typical), with a viewing angle (2φ) of 120° (typical) at 50% luminous intensity. For electrical characteristics, the forward voltage (VF​) at IF​=700 mA spans from a minimum of 1.80 V to a maximum of 2.10 V, with a typical value of 1.97 V; the device is also explicitly noted as "Not designed for reverse operation" under the reverse current (IR​) parameter. Additionally, the electrical thermal resistance from the junction to the solder point (RthJS elec.​) is 1.1 K/W (typical), achieved with an efficiency (ηe​) of 78.8%, supporting efficient thermal management during operation.

3. This section of the OSRAM GH CSSRM6.24 datasheet outlines the Brightness Groups, defined by key optical and efficiency metrics measured at IF​=700 mA. Three brightness groups are specified: V8, V9, and A2, each with distinct ranges for total radiant flux (ΦE​), Photosynthetic Photon Flux (PPF, Φp​), and Photon Flux (PF, Φp,b​). Group V8 has a total radiant flux range of 1035–1075 mW, with PPF spanning 5.66–5.88 µmol/s (typical PPF/W of 4.19 µmol/J) and PF spanning 5.68–5.90 µmol/s (typical PF/W of 4.20 µmol/J). Group V9 covers a total radiant flux of 1075–1120 mW, with PPF of 5.88–6.13 µmol/s (typical PPF/W of 4.35 µmol/J) and PF of 5.90–6.14 µmol/s (typical PF/W of 4.36 µmol/J). The highest-performing group, A2, offers a total radiant flux of 1120–1165 mW, PPF of 6.13–6.37 µmol/s (typical PPF/W of 4.53 µmol/J), and PF of 6.14–6.39 µmol/s (typical PF/W of 4.54 µmol/J). Accompanying notes clarify that PPF ([*]) accounts for wavelengths between 400 and 700 nm, while PF ([**]) includes wavelengths from 280 to 800 nm, ensuring clear context for the photon flux measurements.

4. This section details the Forward Voltage Groups of the OSRAM GH CSSRM6.24 device, defined by forward voltage (VF​) ranges measured at IF​=700 mA. Three distinct voltage groups are specified: Group E1 covers a forward voltage range from a minimum of 1.80 V to a maximum of 1.90 V, Group E2 spans from 1.90 V to 2.00 V, and Group F1 ranges from 2.00 V to 2.10 V. These groupings allow for precise binning of devices based on their electrical performance, ensuring consistent forward voltage characteristics within each packing unit and supporting reliable integration into target applications.
