8. Tambayoyin da ake yawan yi (Dangane da Sigogi na Fasaha)

Q: What driver current should I use?
A: The device is characterized at 200mA, which is the recommended operating point for the specified flux and lifetime. It can be driven up to the absolute maximum of 240mA, but this will increase junction temperature and may reduce lifespan. Always refer to the derating curves.

Q: How do I interpret the luminous flux bins?
A: The bin code (e.g., GW, 3A) defines a guaranteed range of light output. For consistent brightness in an array, specify LEDs from the same flux bin and, if possible, the same voltage bin.

Q: Is a heatsink necessary?
A> Yes, absolutely. With a typical power of over 7W, a properly designed metal-core PCB (MCPCB) or other heatsinking method is required to maintain a safe junction temperature. The thermal resistance value is measured on an MCPCB, indicating this is the intended mounting method.

Q: Can I use wave soldering?
A: The datasheet only specifies reflow soldering parameters. Wave soldering is generally not recommended for such packages due to the extreme and uneven thermal stress it can impose.
