The Lowdown: Sigma Buster 600
Sigma from Germany makes simple solutions for lighting opportunities primarily for commuting, but this Sigma Buster 600 has enough power for trail use. Put one on the bar or helmet or one of each and you're good to go.
It's a 600 Lumen light for $90 and we appreciate the good value. It scores near the head of the pack with a 6.66 Lumen per dollar delivered so it delivers good, reliable value to the consumer. The self-contained light is well made and fairly robust.
It's not the smallest flashlight around, but all that surface area means it can cool itself efficiently with minimal airflow or warm ambient temperatures.
