As you know, LED heat will affect color temperature, VF and lifespan. Portable lighting products are limited in size and have little natural cooling effect. In 2022, Weltool will take the lead in using a through-hole cooling structure, which effectively improves the heat dissipation effect of the light head. This is a Weltool first, the first T2 flashlight with a through-hole cooling structure is coming, and a patent is pending.
