Indoor vs Outdoor Lighting: Are They Interchangeable?

When lighting needs replacement in the office, it is important to pay attention on whether the light bulbs are for indoor or outdoor use. Outdoor light bulbs are more variable. Typically, they are interchangeable for indoor and outdoor use. In contrast, indoor lights are not designed to withstand outdoor temperature changes. Discover which light bulbs are for indoor or outdoor use, or both.

UL Rating

First, the best way to figure out whether a light bulb can be utilized outdoors is by discovering the UL rating. Generally, most lighting fixtures are rated and tested by Underwriters Laboratories (UL). Also, UL has a specific rating for particular locations as well. Below are the different locations and with the corresponding UL rating:

  • UL Listed- Dry Locations: labeled: “UL Listed”
    • includes living rooms, dining rooms, bedrooms, hallways, kitchens, most bathroom areas
  • UL Listed- Damp Locations: labeled “Suitable for Damp Locations” or “Suitable for Wet Locations”
    • includes bathtubs, showers, indoor pool areas, utility rooms
  • UL Listed- Wet Locations: labeled “Suitable for Wet Locations”
    • used both wet indoor and outdoor locations
    • includes gazebos, walkways, open patio and decks, outdoor dining areas

Note on damp rated products or fixtures. Utilize in outdoor areas only when they are fully covered and not exposed to water. For example, a covered patio.

Safe Light Bulb use for Specific Locations

Discover which types of light bulbs can be used indoors, outdoors, or both:

  • LED Lights: used both indoors and outdoors
  • Compact Fluorescent Light Bulbs: used indoors and outdoors
    • check the max temperature the bulb can endure from its packaging for outdoor use
  • Incandescent Flood Light Bulbs: used both indoors and outdoors if not in contact with water
    • used outdoors: incandescent flood light bulbs created to withstand elements
  • Halogen Spotlights and Flood Light Bulbs: used indoors and outdoors
  • Xenon Bulbs: used both indoors and outdoors (double check packaging for particular use)
  • Metal Halide Light Bulbs: used indoors and outdoors

LEDs Expected to Change the Night Skies of Major U.S. Cities

LEDs

Major U.S. cities like New York, Los Angeles, Boston and Seattle are slowly replacing their existing city street lights with more energy-efficient LED lights, a move that is already changing the way these cities look at night, according to a recent article in Forbes. Now, instead of the heavy orange glow people were accustomed to seeing at night when flying in to a city like L.A., a cool silver glow illuminates the city below, leading to blacker skies and brighter streets.

Can LEDs Cut Back on Light Pollution?

LEDs

Aside from enjoying the long-term energy savings of LEDs, many large cities are also hoping to reduce light pollution, a growing concern as our industrial civilization introduces more and more artificial light sources into our once-starry skies, the article indicated. While LEDs by themselves may not reduce light pollution, proponents believe that the true benefit of LEDs is calibrating them to use less light over all. For example, LEDs can also be connected to motion sensors, which can conceivably be used to scale back on lighting when there is no activity on the ground below.

Benefits of LEDs

It’s not surprising that major cities are willing to take on the heavy upfront costs of LED lights once the benefits are considered, which include the following:

  • While LEDs cost significantly more up front than traditional city streetlights, they last significantly longer and emit two to three times more light per watt.
  • Emitting more light per watt means LEDs can provide between 30% and 70% savings on electricity costs in a single year.
  • The digital chips that make up LEDs are only expected to get cheaper over the years.
  • LEDs can also be programmed for other purposes, allowing cities to monitor crime, track the location of power outages and even coordinate disaster relief efforts. Experts are already predicting a boom in lighting controls once LEDs flood the market.

Kirby Electric Provides Lighting Retrofits

While it’s encouraging to see municipalities investing in a cleaner environment for future generations, Kirby Electric has also noticed the move toward energy efficiency on a smaller scale — with our commercial and industrial customers. We are proud to help provide lighting retrofits for our customers that reduce energy costs while boosting the quality of the light in their facilities.
