High Temperature LED Lights
High temp LED lights are specially designed to operate reliably and long-term in extremely high ambient temperature. We offer different types, including high bay(round), flood light(65°C), and linear vapor tight light(75°C). They can withstand ambient temperatures of 65°C/75°C or even higher and are suitable for a variety of harsh industrial areas lighting.
Does 65/75℃ high temp LED lights refer to ambient or operating temperature?
LEDRHYTHM refers to ambient temperature. It indicates that high temp LED lights can safely start and long-term operate stably in ambient temperatures up to 75°C, this is result of our 5000-hour test. During operation, the actual operating temperature of the LED chip, driver, and cooling system will be even higher. This can typically be 20–50°C or more higher than the ambient temperature, depending on the power, design structure, and airflow conditions.
Many high temp LED lighting manufacturers do not specify this in detail; the stated 120°C-150°C may only refer to lamp body temperature. This distinction is important when making a selection.

The results of 5,000-hour testing clearly demonstrate the reliability of our fixtures. These real data proves that LEDRHYTHM LED lighting maintain stable power, lumen, luminous efficacy and color temperature in high ambient temperature areas, ultimately reducing energy and maintenance costs.
Key Features
Our high temp LED lights can stable operation at 65°C/75°C and lifespan exceeding 50,000 hours. They also boast IP65/IP66 ratings and feature high strength die-cast aluminum or PC housings, effectively protecting against dust, water, and corrosion. In order to withstand higher ambient temperatures, in addition to using better and more heat-resistant materials, the most crucial element is driver power supply. The special driver we use is very superior in both heat dissipation and heat resistance.
We have incorporated heat resistant(65-75℃) properties into three mainstream industrial LED light types: high-bay, floodlight, and vapor proof. CCT is 1800K-6500K, luminous efficacy 150lm/W+, 0-10V dimmable. This means it’s an ideal choice for both indoor and outdoor high temperature environments. View details differences about these 3 types of LED.
LEDRHYTHM High Temperature LED Lighting Applications
Ordinary LED lighting cannot withstand extreme heat environments, but LEDRHYTHM three types of high temperature LED lights can be widely used in various harsh indoor and outdoor heat areas. They offer excellent site adaptability and installation flexibility.
- Steel Plants and Foundries: Water vapor, dust, metal particles and high ceilings require highly penetrating light.
- Ports and Outdoor Industrial: Outdoor with heat and extensive operations require wide-area lighting.
- Tunnels and Corridors: Enclosed spaces with heat and humidity. Fixture must be completely sealed and heat-resistant.
- Petrochemical Plants: High temp and corrosive gases require extremely high levels of protection and stability for fixture.
| Type | Typical Applications | Key Advantages |
|---|---|---|
| High Temp LED High Bay Lights | Steel plants, foundries, glass factories, warehouses | Stable performance under 65–75℃, high lumen output, for high ceilings |
| High Temp LED Flood Lights | Ports, yards, or steel mill | Wide beam coverage, durable housing, excellent heat dissipation |
| High Temp LED Vapor Tight Lights | Tunnels, corridors, enclosed workshops, dock | IP66/IP69、IK10, linear design |
High temp LED vs Ordinary LED vs Traditional Fixtures
Professionally designed high temperature LED lights are born for extreme thermal environments, all materials and designs are geared towards better heat resistance and heat dissipation. Ordinary high-bay LED lights, will quickly fail in steel mills. Traditional lighting fixtures have decent heat resistance, but they consume a lot of energy, shorter lifespans, and frequent maintenance.

Color Temperature Selection
In high temperature industrial lighting environments, we recommend combination of high and low color temperatures. This affects both production safety and visual visibility.
- CCT is 4000K-6500K produces bright white light; higher the number, greater the proportion of blue light and clearer the vision, and better detail reproduction. This color temperature is suitable for overall factory lighting.
- CCT light below 3000K, and even at 1800/2200K, tends to be yellowish and amber, with higher proportion of red and yellow light. It has stronger penetrating power and can reduce thermal shadows caused by steam and dust.
1800K/2200K is one of our main features. In heat furnace and steam vent, the air is full of thick steam, dust, or iron filings, so a low color temperature is the best choice. Learn more about 1800K/2200K in high temperature lighting, please see related articles.
