Our review


The G502 Lightspeed is the fourth iteration of the G502. First released in Proteus Core version, then in Proteus Spectrum which added an RGB backlight, the G502 was recently declined in Hero version, without however that Logitech does not change anything other than its sensor. The Lightspeed version, for its part, is a wireless version of the Hero, but takes the opportunity to evolve more in depth. Despite the integration of a battery, it is especially lighter thanks to an internal reworked design that we will explain in more detail below. The ultimate version of the G502?



Generalized on the last mice of the G range from Logitech, the Hero 16K sensor drives this G502 Lightspeed. It offers impeccable performance for the mouse, working at speeds of 10.16 m / s (7.6 m / s for the PMW3366 of the G502 Proteus Spectrum) and supporting acceleration up to 40 g. No acceleration, smoothing or filtering software to deplore, the 1: 1 tracking is impeccable.

Question sensitivity, it is once again much more than necessary, with a maximum value of 16,000 dpi, completely unusable in the state of current technology. At this extreme sensitivity, a movement of only 2 cm is enough to make the mouse pointer run the full width of three Ultra HD 4K screens. Cannot be used, even for quick U-turns in an FPS, for example. We will say that such a sensor is not likely to be exceeded if the definition of the screens were to increase faster than expected.

We also appreciate the qualities of recognition of the surfaces of this sensor which works very well on satin coatings, in wood, plastic or metal, as long as they are neither too shiny nor too transparent. Glass remains the prerogative of laser sensors, but in all cases we recommend using a good mouse pad to improve glide and precision while reducing wear on the skates.

In terms of wireless connection, we can say that Logitech perfectly masters its subject. The Swiss manufacturer has already demonstrated this with its other G mice such as the G900 and G903, or more recently still the G Pro Wireless, its Lightspeed technology offers performance identical to that obtained with a wired link. The latency is thus just as undetectable and the stability of the link flawless. We can really forget the wired connection which will ultimately only be used during recharging.



The G502 Lightspeed is undoubtedly the best version of the G502. As fast as the G502 Hero, it is lighter and loses no quality. Logitech unfortunately makes paying quite expensive for this transition to wireless with an introductory price of 149 €, ultimately quite close to that of the G900 that we find even today a few euros less.
