Thermal Runaway Free - Light Source
The PEACE light source is a groundbreaking LED innovation, completely free from thermal runaway. It was born from the fusion of Grantz Technology’s patented “Azteca Cooling” system—which stably dissipates the heat generated by LED elements (approximately 70% of input power)—and the highest-grade LED chips, co-developed with a leading Japanese manufacturer.
This light source represents the pinnacle of Japanese engineering and pride. It is the result of Grantz Technology’s relentless pursuit of excellence, turning the lighting industry’s “impossible” into reality, in collaboration with Japan’s foremost LED chip experts.
PEACE light sources solve the following common issues in LED floodlights:
Lifespan issue LED floodlights experience a significantly shortened lifespan, unrelated to the LED chip's lifespan, due to thermal runaway caused by insufficient cooling. This leads to internal overheating and failure of electronic components, rendering them inoperable. |
Illuminance drop issue LED elements gradually lose brightness when temperatures exceed a certain threshold due to thermal runaway, and illuminance decreases accordingly. |
AZTECA Superlight: The perfect floodlight featuring the new “PEACE Light Source”
The “Azteca Superlight” features the new “PEACE Light Source,” combining top-quality Japanese-made LED chips with fan-less stable cooling via the patented “Azteca Cooling” technology. Furthermore, by integrating Granz Technology's proprietary optical technology, it solves another common LED floodlight issue—the “Haze phenomenon”—achieving performance specifications that set it apart from existing conventional products from other companies, truly reaching another dimension.

Dyson’s public stance emphasizes that the high operating temperature of conventional LED elements is the singular failure mechanism preventing LEDs from achieving their inherent long lifespan. Here is a summary of their claim regarding the high temperature issue, including the precise quote and corresponding source:
Dyson frames the thermal problem as the fundamental flaw in standard lighting products. They assert that while LEDs are technically capable of lasting for decades, most fixtures fail prematurely because they lack effective thermal management. The subsequent overheating leads to an irreversible decline in light quality.
Core Failure Temperature Claim:
Dyson specifically references the dangerous thermal environment common in conventional fixtures as the standard they sought to overcome:
"LEDs can last a long time but, due to exposure to heat – typically 130 degree C (266 degree F) – they tend to die because the phosphorous coating gets warped." 1
Mechanism of Degradation:
When LEDs overheat, the high temperature causes the essential phosphor coating—which converts the light from blue to white—to physically degrade. This results in the light output fading and discoloring over a short period.2
The Engineered Solution and Contrast:
Dyson’s proprietary Heat Pipe Cooling Technology (HPCT), inspired by satellite cooling systems, was designed specifically to combat this 130 degree C problem (266 degree F).5 By actively drawing heat away from the clustered LEDs, Dyson states the operational temperature is kept well below this critical threshold, with a technical specification limiting the operating range to a maximum of 60 degree C (140 degree F).7 This thermal control is the basis for their claim that their lights maintain quality for up to 60 years.4

ECO is said to derive from the Greek word OIKOS (house). From ECO's meaning of “household management, economy,” ECONOMY is said to have been derived, and from ECO's meaning of “home, habitat,” ECOLOGY is said to have been derived. Fundamentally, pursuing ECOLOGY (environment) should lead to ECONOMY (cost reduction).
