Our Verdict

Logitech G502 LIGHTSPEED

Logitech G502 Proteus Spectrum

The Logitech G502 Proteus Spectrum is a predecessor of the Logitech G502 LIGHTSPEED. The biggest difference is that you can connect the LIGHTSPEED wirelessly with its USB receiver, and it recharges with an impressively flexible micro-USB cable. The sensor is also updated and has a much wider CPI range, a lower lift-off distance, and marginally lower click latency when wired, though it's likely too small of a difference for most people to notice.
