What Do All Those Letters Mean? Part 2: Ratings & Temperature Classifications

IP stands for Ingress Protection.
You’ll commonly see ratings such as:
IP65. IP66. IP67
Those two numbers aren’t random.
The first digit tells us the level of protection against solid objects and dust.
The second tells us the level of protection against water.
Take IP66.
The first 6 means the enclosure is dust-tight.
The second 6 means it is protected against powerful water jets.
Think of IP as a bouncer standing outside the fixture.
Dust? You’re not on the list.
Water? Let’s see what that second number says.

Now take IP67.
It maintains the highest dust-protection level while adding protection against temporary immersion in water under specified test conditions.
That’s an important distinction.
IP67 doesn’t simply mean “better than IP66.”
The ratings represent different standardized water tests.
IP66 addresses powerful water jets.
IP67 addresses temporary immersion under specified conditions.
So which is better?
The one appropriate for the application.

What Do All Those Letters Mean? Part 1 – Hazardous Location Classifications & Certifications

Industrial lighting specification sheets often contain classifications and certifications that indicate where a fixture can be safely installed. Class 1 refers to flammable gases, Class 2 to combustible dust, and Class 3 to ignitable fibers, while Divisions and Zones describe how frequently the hazard may occur. Standards such as UL 844, CSA, ATEX, and IECEx confirm that equipment has been evaluated for specific hazardous applications. Knowing the difference between location classifications and product certifications is essential for choosing safe, compliant lighting.

Emergency Lighting Isn’t Optional: What Codes Actually Expect

Emergency lighting is critical in industrial and hazardous environments, helping personnel evacuate safely and shut down dangerous processes during power outages. Codes generally require systems to activate automatically within 10 seconds, operate for at least 90 minutes, provide adequate illumination, undergo regular testing, and be certified for hazardous locations. Red Sky Lighting’s RDX EM Series exceeds these standards with up to 180 minutes of runtime, outputs from 6,000 to 29,000 lumens, and reliable operation in temperatures up to 140°F (60°C).

Two Weeks Can Change Everything

Scheduled maintenance is expensive. When planned lighting shipments fall behind schedule, perfectly laid-out projects begin to slip. Delays cost money and kill project momentum: schedules shift, crews idle, safety risks rise, and mounting pressure falls on onsite management.
That’s why Red Sky’s quick delivery is far more than convenience — it’s a practical solution. Most of our orders ship in two weeks or less. Speed means nothing without reliability; trust is earned not from empty promises, but consistent execution. In industrial sites, lighting dictates visibility, safety and production progress. Whether orders are pre-planned months early or rushed amid unexpected shutdowns, timely delivery decides if a project moves forward or stalls.
Sometimes the line between costly delays and smooth progress hinges on equipment arriving exactly when needed. And Red Sky’s fast delivery promise is exactly what turns the tide.
Two Weeks Can Change Everything.

International Day of Light: The Moment Light Matters Most Is When It Disappears

International Day of Light is meant to celebrate innovation, science, technology, and the role light plays in our everyday lives.In industrial environments, light means something even more immediate.
Safety.
Visibility.
Confidence.
The ability to keep people moving, working, and getting home safely.
Because most people don’t think about light until it’s gone.
