What's the difference between UV and LED blood tracking lights?

UV blood tracking lights and LED blood tracking lights differ primarily in their technology and effectiveness in different environments:

UV Blood Tracking Lights
- **Technology**: Use ultraviolet light (typically around 365nm) to make blood fluoresce or glow in the dark.
- **Effectiveness**: 
  - More effective on darker terrains and for detecting dried blood.
  - Generally requires additional chemicals like luminol to enhance visibility of blood.
  - Less effective in outdoor environments with natural materials like leaves, dirt, and grass.
- **Applications**: Commonly used in forensic settings rather than hunting.

LED Blood Tracking Lights
- **Technology**: Use high-intensity LEDs with specific wavelengths (typically in the blue spectrum) to enhance contrast between blood and natural materials.
- **Effectiveness**:
  - More effective in outdoor hunting environments by creating contrast against leaves, dirt, and grass.
  - No need for additional chemicals.
  - Often have multiple modes for different tracking conditions.
- **Applications**: Designed specifically for hunting scenarios to help track wounded game.

Key Differences
- **Mechanism**: UV lights rely on fluorescence, while LED lights enhance contrast.
- **Practicality**: LED lights are generally more practical for hunting due to their effectiveness in natural environments and lack of need for additional chemicals.
- **Versatility**: Some blood tracking lights combine both UV and LED technologies for maximum flexibility in different tracking scenarios.

For most hunting applications, LED blood tracking lights are more effective and easier to use without requiring additional substances. UV lights might be better for specific situations where blood needs to be made to glow, but they typically require luminol or similar chemicals to work effectively in field conditions.
