Re: Self-luminous exit signs
Roger, yes, Brady Glo does look to be similar to the 3M product. The better choice would depend on the end user's requirements. Brady Glo looks like a good choice for HIGHLY industrial environments where all you need is a sign, since it resists so many chemicals, and only comes in a sign format.
The 3M product (a low cost pressure sensitive adhesive vinyl) looks better for non-highly industrial environments where luminance is needed in more non-traditional places like door frames, stairs, low level, and railings, in addition to exit signs. And it only takes 3-5 minutes to charge, where the Brady Glo takes an hour.
Either way, it's obvious there are better choices than tritium out there.
