Comparison with Similar Models:
| Model | Brightness | Vf | Viewing Angle |
|---|---|---|---|
| XLM2DG14W | 11,990mcd | 3.2V | 30° |
| Kingbright WP710A10GD | 8,000mcd | 3.2V | 30° |
| Lite-On LTST-C191KGKT | 9,500mcd | 3.4V | 20° |
Advantage: XLM2DG14W offers 20–50% higher brightness than competitors at similar voltage.
Industrial Control Panels: Status indicators for machinery (high brightness ensures visibility in noisy environments).
Automotive: Dashboard backlighting and warning lights (525nm green meets SAE J578 color standards).
Consumer Electronics: Power buttons or charging indicators (low Vf extends battery life).
According to Global Industry Analysts, the LED market will reach $127B by 2027, driven by:
Demand for energy-efficient lighting in smart cities.
Growth in automotive LED adoption (e.g., EV charging status lights).
The XLM2DG14W’s high brightness-to-power ratio positions it well for these trends.
Use Ohm’s Law: R = (Vsupply - Vf) / I = (5V - 3.2V) / 0.02A = 90Ω (standard value).
Yes, SunLED rates it for 20mA continuous current with proper heat dissipation.
Narrower than diffused LEDs (typically 60°+), making it better for directional indicators.
Yes, its IP40-rated package resists dust and moisture (though additional sealing is recommended for harsh environments).
Yes, SunLED confirms compliance with both standards.
With advancements in miniaturization and higher efficiency, future iterations may offer:
Increased brightness (>15,000mcd) at lower currents.
Surface-mount variants for compact PCB designs.
