Sigma Buster 2000 £252.99
The Buster 2000 is heavy, but that gets you serious power and longevity with tons of useful features. Its claimed 2,000-lumen output actually seems higher, with long centre-point reach and a clear, consistent secondary spread out to smooth, eye-friendly edges. The triangular three-LED head comes on a thumbwheel-secured band that works with 35mm bars (if you pull the padding out). Helmet and GoPro-style mounts are also included. There’s a wireless remote too, with a secondary button that just toggles through the steady modes, dodging the strobe and pulse settings. The square plastic battery is bulky and contributes to the heaviest weight on test. Run times are impressive though, and it’s got a fourstep charge indicator. While it’s a new light to us, reliability is sound so far.
