How do I determine the best beam pattern for my bike light, considering factors like riding environment, speed, and personal preference? Id love to hear from those who have experimented with different beam patterns and have some insight into what works best for various types of riding. For example, is a spot beam better suited for high-speed road riding, while a flood beam is more suitable for slower, more technical mountain biking? Are there any general guidelines for choosing between a narrow, focused beam and a wider, more diffuse beam? How do factors like ambient light, road surface, and surrounding terrain impact the effectiveness of different beam patterns? Im interested in hearing about the experiences of others and learning more about the science behind beam patterns, so I can make an informed decision about the best light for my needs. What are the key considerations when choosing a beam pattern, and are there any specific products or manufacturers that are known for their well-designed beam patterns? Are there any resources or tests that can help me determine the best beam pattern for my specific riding style and environment?
