Excellent Heat Dissipation Construction
LASFIT bulbs use built of lightweight and high-strength aluminum alloy as bulb body to keep themselves cool, even if they're used in constant-on applications like daytime running lights, they still illuminate non-fading brightness. Some bulbs, which were covered in many LED chips will haven't enough cooling surfaces.
