Photoluminescent Exit Sign Green - Aluminum Code Approved UL 924 / IBC/NFPA 101 | NightBright USA Part Number ULG-050

glows in the dark, passed my fire inspection

For our condo, in response to recent Fire Department inspection, we had to put up some signs. OK. Found these on Amazon and ordered 4 after the FD inspector had seen a snip of the web page and said OK - Good to go. Arrived quick and nicely packed. Took out 1 for evaluation and put it up where instructed with temp industrial double-sided tape. Outside. Noted that the glow did not last all night. So called seller and got a call-back Now I know. 90 min glow and no more to be expected. Outside might cause fading of the green background in time. Seller (while driving his truck in Texas) kindly explained to me all about photoluninescent signs. Now I know. Cannot do better for sales support. Ever.

Works great and is very visible

Normal

Semi-photoluminescent. Not super bright if only exposed to indoor lighting. Either way it's very visible and the arrows are easy to spot from a distance.

The presence of the NFPA and UL ratings, makes this sign a win for me. The sign glows very brightly in the dark. It was surprisingly bright. The high quality is commensurate with its premium price. Would buy again.

I installed this in a commercial space over a door that had some illumination after the insurance company inspected the space and required a better sign. This is not powered by electricity, but it is highly reflective and glows for a while after the lights are shut off, at which point the business is closed for the day anyway. I sent photos to the insurance company and they were satisfied. Note, the adhesive is strong... I hopefully will not have to move this anytime in the future.

The inspector was very dubious about this concept but he thought they were super cool when he finally saw them. They passed inspection and i saved hundreds of dollars by not having to higher an electrician to hard wire signs in. Apparently in a commercial setting you aren't allowed to do plumbing, electrical, etc; it has to be done by a licensed contractor in that field.
