Reviews
The glow is strong and you can read it from a good distance. The only downside is the board feels a bit lightweight - I worry about long-term durability if used outdoors. For inside use this is a solid pick.
I installed this in a utility corridor in our building. The rigid plastic feels durable, and even after several hours in the dark the sign is still clearly visible. Looks professional and gets the job done
The sign itself is solid and the glow works well. My only complaint is that the adhesive backing struggled on a slightly rough door surface, so I had to add a couple of extra screws. But it works perfectly now.
This sign is exactly what I needed. In low light it’s still very visible, and the letters stay crisp and legible. The glow lasts a good while, and I feel confident that staff will notice it even when lights are off. Great quality.
This door sign exceeded my expectations. The glow is consistent and readable, and the print is bold and easy to read. It’s also weather resistant enough to survive occasional moisture in our corridor. I’d order more without hesitation.
