Although every manufacturer claims that their box light is waterproof, leakage is still the main complaint. Tecniq solved this problem by designing the light engine to be less than 0.6″ thick. This allows them to guarantee a perfect, waterproof seal every time. And despite the T85’s unique design, it still fits in the industry-standard spacing, and uses standard hardware. If you ever manage to break the lens and the light fills with water, rest assured that the potted circuitry guarantees it will still continue to work for years! Backed by TecNiq’s life time warranty.
