Grote Industries said its new MicroNova Dot is a family of clearance/marker lamps with dual intensity capabilities that are specifically designed to resist the dimming that is common in other penny-sized LED lamps.

According to the company, vehicle wiring systems carry negative transients as a byproduct of their interaction with motors, relays and solenoids. Over time, exposure to negative transients has been demonstrated to degrade LEDs, diminishing their light output and viability in the process. All Grote LED lamps are designed with a rectifier diode that protects its LEDs from the effects of negative transients, according to the maker.

“We have engineered all Grote LED lamps to resist the wear and tear that negative transients place on LED lamps,” said John Grote, vice president sales and marketing for Grote Industries. “The LEDs in the new MicroNova Dot were specially designed to allow room for the addition of rectifier diodes.”

The MicroNova Dot is expected to outlast and outperform all comparably sized LED lamps on the market, the company said. The lamp is designed for dual-intensity performance and, in addition to coming in standard red and amber colors, is also available in white.

It is available in P2- and PC-rated versions that allow it to meet the photometric requirements for a broad spectrum of applications, Grote said. The P2 designation means that the MicroNova Dot can be used as either a sidemarker lamp or a clearance lamp, but not both at the same time. The PC designation means the lamp will meet light angularity requirements for both the clearance and sidemarker lamps simultaneously.

The lamps require no mounting fasteners and have a profile that extends only three-eighths of an inch from the mounting surface. It comes in a 12-Volt model and a 24-Volt, ECE-rated model. An optional adapter adds even more flexibility to the line by allowing the lamps to function in a dual-intensity mode, needed for applications such as high-mount center lamp configurations, according to Grote.
