The Kolma QH50M represents the next generation of pest control technology for 2025. This flagship 5W model is specifically engineered to bridge the gap between high-performance industrial power and elegant residential design.
The standout feature of the QH50M is its Dual-Wavelength UV-LED technology. By emitting a precise combination of 365nm and 395nm ultraviolet light, the device taps into the natural phototactic instincts of a much broader range of flying insects—including stubborn mosquito species and moths—more effectively than single-spectrum lamps. Once lured, pests are eliminated by a powerful internal grid that delivers up to 3000V of high-voltage impact.
Built with a robust IPX4 waterproof rating, the QH50M is at home both in a sleek living room and on a rain-exposed garden patio. Its durable ABS housing and waterproof cap switch ensure longevity in all weather conditions. Despite its compact footprint, it offers a massive 80m² effective coverage area, making it the ultimate choice for large courtyards, terraces, and spacious indoor areas.
