Industrial Lighting 101: Impact of dust and dirt on thermal management

Heat is the killer of all things electronic. LED fixtures are no different. Fixtures need to be designed with superior thermal management in mind. This includes preventing dust and dirt from building up and trapping the heat inside the fixture. A dusty, dirty layer of insulation will lead to overheating and early failure.

Industrial Lighting 101: Best thermal design for dirty industrial facilities

Upgrading the LED lighting in your industrial facility? Make sure to consider the ambient temperature – many times you’ll see temperatures exceeding 140°F. Plus, the fixtures are likely to be exposed to dust, gases and manufacturing debris. Poorly designed LED fixtures often have limited-ability heat sinks to begin with. Many others have fins that will collect dust and other debris, creating an insulating layer that severely diminishes its capacity to dissipate heat, reducing its life and performance. In this article, we’ll explore how to find LED fixtures with the best thermal design to perform well under these harsh environments.

Make sure it is a true 65C fixture

Industrial Lighting 101: Make sure it is a true 65°C fixture

Are you upgrading the LED lighting in your unconditioned facility? Don’t be fooled by the “advertised” ambient temperature rating claiming it is a 65°C fixture. Many manufacturers use potentially deceitful spec sheets to make you think their fixture will withstand those high ambient temperatures. The marketing claims and the fine print in the spec sheets are contradictory. Make sure it is a true 65°C fixture.

How to illuminate a hangar

How to illuminate a hangar

Learn how to illuminate hangars. After designing aircraft hangars for a variety of clients, ranging in size from small, corporate facilities to massive projects for the U.S. Air Force, we have found they all have very similar lighting design challenges. In order to meet the typical hangar lighting requirements, here are my recommendations on how to illuminate a hangar.

Overstating Performance – Look Out for the Spec Sheet Star!

As you know from the previous three parts of this blog, when a light fixture’s output equals 70% of its initial output, it is deemed unacceptable.  This will require the owner to replace the light in order to provide a safe workplace.

How to choose the right lumen output when replacing conventional light fixtures.

Choosing the right lumen output of an LED fixture to replace conventional light sources isn't a simple formula. There are many things to consider, including initial lumen output, optical efficiency and lumen maintenance.

Measuring Ambient Temperature at Fixture Height

L70: Can we accurately predict L70?

The short answer is that we can’t. Worse is we don’t even fully know the variance. The good news is that LEDs will last longer than traditional light sources but nobody knows exactly how long.

L70: What causes some LED lights to reach L70 faster than others?

The major cause of LED fixtures losing light output faster than others is low-quality components. As with any engineered product, the manufacturer must make choices - and compromises - on the level of quality of materials and components to be used for the finished product in order hit the cost targets. This is no different when manufacturing LED fixtures.

Lumen Maintenance Warranty

L70: What is it and why do we need it?

When purchasing LED lighting, read the warranties carefully. Most warranties do not cover when an LED fixture does not meet its advertised performance, leaving you in the dark, light-wise and warranty-wise. Unlike most, Flex Lighting Solutions provides a true and transparent 5-year lumen maintenance warranty.
