Illuminated Reverse Channel Letters

“Toscana Divino” Restaurant.  We installed this exterior wall sign at the Central Square of Mary Brickell Village in Miami on April , 2012.  

These are Illuminated Reverse Channel Letters, solid aluminum faces and sides.  They have open backs for a “halo” effect, since  the letters are mounted away from the wall.  

These Illuminated letters can receive either LED or Neon Lighting.  For “Toscana Divino”  we used red LED. 

American Tropical Signs & Services can produce custom logos and letters in regular channel, open face, or reverse channel letter signs.  For the restaurant,  the letters are  pre-wired and  installed on a 2″ deep panel, concealing all the wiring and power supply, since there was no access behind the wall for all the wiring.



Our Signs are UL Listed

Our signs are UL Listed.  What does it mean?

Underwriters Laboratories Inc (UL)

UL’s safety certification services include testing, evaluation and factory surveillance of products to national, regional and international safety standards. These certifications enhance the safety of products, as well as the public’s confidence in their compliance. Consumers, retailers, insurers, distributors and regulators recognize the familiar UL Mark as a trusted symbol of safety.

WE ARE “UL” CERTIFIED, all our electrical signs will have UL Labels.

History of Underwriters Laboratories

In 1894, William Henry Merrill, an electrical engineer, founded UL. Prior to founding the company, Merrill had served as an electrical inspector for the Boston Board of Fire Underwriters, an electrician for the Chicago Underwriters Association and as an electrical inspector for the Chicago World’s Fair. At the World’s Fair, Merrill was hired to examine the electrical safety of the Columbian Exposition’s Palace of Electricity, the first large-scale use of electricity for illuminating. The proliferation of untamed DC circuits and the new, higher voltage AC currents caused a great deal of concern and a rash of fires. Critics questioned if the new technology would ever be safely harnessed. Merrill assured that it could be with the proper care, handling and understanding of its potential hazards.With this goal in mind, Merrill conceived of the idea of an independent testing facility that could render expert opinions concerning fire hazards and certify electrical devices. At first rejected, the need for such a laboratory became clear and UL came into being. From that point forward, UL has been a pioneer and leading authority in testing and creating safety standards.





Neon Signs – History of Neon

American Tropical Signs & Services, LLC  fabricated and installed this NEON sign  in Miami Beach, Florida.

The history of neon sign technology dates back to 1875 before the age of electricity, when the French Astronomer Jean Picard observed a faint glow in a mercury barometer tube. When the tube was shaken a glow called barometric light occurred.  By 1900 after years of experiments, several different types of electric discharge lamps or vapor lamps were invented in Europe and The United States.

The French engineer, chemist, and inventor Georges Claude (b. Sept. 24, 1870, d. May 23, 1960) was the first person to apply an electrical discharge to a sealed tube of neon gas (circa 1902) to create a lamp. Georges Claude displayed the first Neon Light tube on Jan. 11 th, 1910 in Paris.  Georges Claude patented on Jan.19th, 1915 – US  Patent 1.126.476

By 1923 Neon Signs became symbols of glamor and progress

The technical information for this page was written by Daniel Preston who is an inventor, an engineer, a member of the technical committee of the International Neon Association and the owner of Preston Glass Industries.

How are Neon Signs Made:

Neon signs are glass tubes bent into shapes and filled with inert gas.  When the electric current hits the electrodes flowing through the gas,  its atoms glow.

The type of gas in the tubes, determine the color of the light.  In a clear tube, argon gas is blue, while neon gas produces red light.  Other colors  are obtained by using glass tubes that are coated in fluorescent colors.  Blue argon gas in a yellow tube, emits a green light.

To shape the tubes, glass blowing techniques are used.  Following a fire resistant pattern, tube is marked where it needs to be bent . Then heat is applied to each spot on a burner that has a propane flame at 1200 degrees F.  In about 30 seconds, the glass becomes soft enough to be pliable.  The tube is bend gently, and later, air is blown to restore the original diameter.

While the market for neon lighting, in outdoor advertising signage has declined since the mid 20th Century, in recent decades neon lighting has been used consciously in art, both in individual objects and integrated into the architectural design of buildings. Neon tubes fabricated by a sign manufacturer, and designed to follow a building architectural angles or shapes can become exterior illuminated signage by creating a colorful and eye catching night time look without the use of typical channel letter signs or box signs.

PVC Sign for Montessori School in Miami

   American Tropical Signs & Services, fabricated and installed  this exterior PVC sign in Miami.  ”Mia Piccolo Montessori School”,  was completed in May, 2012. Our PVC letters are made from a closed-cell rigid PVC which gives great strength, smooth, full colored, and edges with a quality finish. Our laser cutter and computer driven routers cut each letter with precision, capturing every detail of the style selected.  In this case,  we used ½ inch thick black PVC and we overlaid full colored  graphics and high performance vinyl on the faces of the letters.  Each character was  mounted with metal studs behind each letter and flush to the wall. 


Coral Gables Art Cinema Sign

American Tropical Signs & Services fabricated and installed this eye-catching powder coated sign at Coral Gables Art Cinema in Coral Gables, Florida.  It consists of two aluminum panels, mounted on two 3” by 3” square tubing.  For depth, the logo was custom – made in formed plastic and the back panel was placed to cover the back of the letter’s attachments.  What makes this exterior sign distinct is its finish.  A powder coated painted sign  provides a robust finish to the surface and acts like armor against scratching, corrosion, fading and wearing.  Powder Coating Paint is the fastest growing finishing process in the country because unlike other metal finishing techniques that depend on chemicals and solvents,  uses electrically charged pigments.  The result is a beautiful uniform coating that withstand the most rigorous exterior conditions.

Our  satisfied client says

It looks beautiful, exactly how we imagined it, and your two staff members did a great job of installing down to every detail. We love it! :)
