I buy this head lamp to light in winter when jogging. Since I usually walk in a nature reserve, I need a relatively bright head lamp. Because of the good review of this product I decided this lamp from Sigma Sport in Amazon. Shopping at Amazon is always so convenient, fast delivery, top service. The lamp works so well properly. There are three level of brightness. Unfortunately, the power is low. Both have been set, the third stage, the lamp is not as bright as expected. It's really difficult, with this lamp to walk in the dark. The headlamp is however definitely for reading in bed sufficient. So Conclusion: Top quality, fast delivery, top service, power is not sufficient for running in the dark.
