LED Technology

Not all LEDs are made the same It is critical to understand how to design the LED system and choose the appropriate LED for a given application. At Principal LED, we understand the fundamentals of LED technology and how to apply it to sign products that are built to last in the most demanding outdoor applications.

LED Module

Many LED module manufacturers utilize through hole technology that evolved from historical indoor and short use applications. This includes 5mm and piranha packages that have poor thermal resistivity (i.e. the amount of heat that is removed from the LED to the substrate). Others use surface LED (SMD) devices; however, they do not use enough metal or a high thermal conductivity metal (like high purity copper) that allows the substrate to adequately remove the heat..

High Quality Manufacturing

At Principal LED we utilize only high purity copper clad PCBs coupled with small distributed chip or die packages with low thermal resistance to create a long life product that can handle elevated outdoor temperatures. Due to the relatively low cost of entry into the LED module industry, the market has been flooded with low-cost products that are not optimized or tested for demanding outdoor sign applications.

The P-LED Advantage


LEDs produce more light per watt of electricity than traditional light sources. This results in energy savings as high 7x over traditional lighting.

Low Voltage

LEDs operate at low voltages, reducing electric shock and fire hazards.

Size & Form

LEDs light sources are tiny semiconductor chips or die, often 1mm2 or smaller, enabling new form functions and reducing the profile of illuminated signage.


Properly operated and designed, LEDs will last up to 50,000 hours or longer.

Cold Weather

LEDs do not dim in cold weather and perform well in extreme cold conditions.

Shock Resistance

LEDs do not contain glass, therefore are inherently resistant to shock and breakage, unlike fluorescent and neon tubes.


LEDs are environmentally friendly and do not contain mercury like fluorescent and some neon tubes.

Huge Savings

Dependability and performance you can count on at prices you can afford. That’s a bright idea.
