Reviews
Reliable and well-made sign that performs well during darker conditions and power cuts. Arrived securely packaged and looks excellent once mounted.
Very professional looking sign with bright glow visibility and sharp printing. It was easy to install and fits perfectly with our fire safety procedures.
Good sturdy sign that glows well and feels durable for long-term use. The print quality is excellent, although I would have liked larger sizing options.
Excellent glow in the dark fire door sign with very clear lettering and strong night-time visibility. It adds an extra level of safety to our building during low light conditions.
