Selection and Application Guidance
The key difference between straw-hat and round-head LEDs is the viewing angle: the straw-hat structure spreads light across approximately 120°, allowing a single LED to cover a larger, uniformly illuminated area. This makes it ideal for LED strips, fluorescent-style tubes and wide-angle panel indicators. The trade-off is lower luminous intensity (mcd) than focused round-head LEDs; selection should consider illuminance across the entire surface, not just the mcd value. The white versions in Hongcheng Optoelectronics' 5mm straw-hat series cover 2700K~6500K with a color rendering index of Ra≥80, and undergo consistency screening at a constant current of 20mA for LED strip applications, ensuring uniform brightness in series operation.

Selection Recommendations
Through-hole LED lead polarity is long lead positive and short lead negative. Recommended soldering conditions are within 260℃/3 seconds. Forward voltage varies by color (1.8~3.4V); select the current-limiting resistor for the actual color.
