The ST / T Evolution range of products feature highly efficient, premium ÔbinÕ 11W LEDs in combination with vacuum-metallised conical optics to deliver a powerful beam pattern with wide spread. This makes the products especially well-suited to rural and off-road applications. Incorporating the same electrical and product design across both ST and T lights, the former indicates lights that are UNECE certified to Regulation 112 as high beam driving lights, while the latter indicating the larger light bars not certified and intended for off-road use only operated via an independent switch.
