Gemlite™ Lighted Formed Plastic Letters

Gemlite or Lit Formed Plastic are a 2 part plastic letter based on the popular formed plastic product produced for over 60 years. A molded plastic face fits over a molded plastic back that contain the LED modules. Traditionally this was a stepped return which partially revealed the white plastic back but we have recently introduced a full depth face that hides the back entirely. Gemlite is made in 5 different variants to suit different requirements. The material used for the face and back is a cotton based plastic known as CAB(Cellulose Acetate Butyrate) which is a durable plastic that remains flexible in all environments.

Lit formed plastic letters and logos are entirely produced in the USA and carry a manufacturer's lifetime warranty. LEDs on the other hand will not last forever. Most systems are designed to last approximately 50,000 hours, or around five years. After the LEDs fade or burn out, they will have to be replaced. Power supplies and LED modules ar UL Certified and carry a 5 year warranty.

The mount includes threaded blocks solvent-bonded to the letter back to receive a 10-24 threaded aluminum stud. Silicone adhesive should be applied to the studs and into the drilled holes at installation.A full size install pattern is included.

Gemlite Formed Plastic letters and logos are available in five variations.

  • While it is possible to have more than one color on some variations the price would be much greater. For instance, on halo backlighted letters, the edge and face color could be painted differently but it would add another 50% to the cost due to paint masking. If this is desired it would need to be done as a custom addition. Call or email for details.

Return Style

  • G100, G200 and G300 have 2 types of edge returns available. The stepped edge leaves some of the backplate showing while the full depth edge allows the face plate to fit seamlessly over the backplate. The stepped edge is cheaper and is the default selection.
