Product Description


The longest-lasting exit sign in existence, our 20 year self luminous exit signs will actually be saving you money and time which more than pays for their modest price tag. Put these self-powered exit signs up in nearly any type of business or government facility for a hassle-free fixture.

SLEX-20 self luminous exit signs use vacuum sealed tritium tubes instead of electric bulbs to provide a glowing 'exit' legend. The tubes have an inner coating of phosphor that, when interacting with tritium, causes the tubes to glow continuously without ever having to charge or maintain them.


  • No back-up battery or AC input required!
  • No maintenance needed during 10-year lifespan
  • Frame and housing options
  • 10-year warranty
  • UL 924 listed for Wet Locations
  • Can be used in Class I,II or III hazardous locations



SLEX-20s come with their own universal mounting canopies and fasteners. The canopy is weather and corrosion resistant aluminum and can be used in a wall, ceiling or edge-mounted fashion.

External Specifications

The border, trim and back-plate (on single sided models) of the self luminous exit sign is white corrosion-proof ABS thermoplastic, though aluminum and vandalproof models are available. A clear polycarbonate panel protects the tritium tubes and stencils inside from external duress.

Internal Specifications

Our SLEX-20's power source is the phosphor coated tritium tubes, filled with an isotope level high enough to stay charged for two decades of use. The tritium, while radioactive, produces less radiation than a home smoke detector when sealed in the vacuum tubes.

  • UL924 for USA and British Columbia
  • CS860 for use in Canada and Quebec
  • NEC 500 & 700 (NFPA Ch. 50 & 70)
