2017 Light Bulb Buying Guide – Part 2

In our blog post PKK Lighting 2017 Lightbulb Buying Guide – Part 1, we provided a short history lesson about light bulbs and the transition from incandescent bulbs and fluorescent tubes to more energy efficient LED light bulbs.  In this post we will provide additional guidance as to some of the key features and functionality that are important considerations when purchasing LED light bulbs.

When you are in the market for an LED light bulb, there are a few things you need to be familiar with before you buy:

  • Shape – LED bulbs come in a range of shapes and sizes.
    • The standard shape (A19) is the most common shape and is used in table lamps and other general purpose applications.
    • Reflector bulbs emit light to a specific area and are generally used in track lighting, under cabinet installations, and ceiling fans.
    • Candle shaped LED bulbs are generally used in chandeliers or other decorative fixtures.
    • Globe shaped LED bulbs are typically used in bathroom vanities, pendant lighting, and other specialty fixtures.
  • Color – the color of the LED bulb is designated on the Lighting Facts label (see below). Warm colors are more yellow while cool colors are more blue. Color temperature is measured in units of Kelvin, ranging from Amber (warm) light at 2200K, to Daylight (cool) at 5000K-6000K, and many colors in between.
  • Brightness – the brightness for LED bulbs is measured in lumens. Here is a lumens to watts conversion table so you can determine which LED is right for the job.  Note that the wattage for LED bulbs is one-fourth that of the incandescent bulbs, which is where much of the energy savings comes from by converting to LED’s.  As an example, if you want the approximate light from a pair of 60W incandescent lights in your bathroom, you’d use a pair of 900 lumen LED bulbs that are 15W each.
Lumens Incandescent
light bulb
watts
Fluorescent
/ LED
watts
375 lm 25 W 6.23 W
600 lm 40 W 10 W
900 lm 60 W 15 W
1125 lm 75 W 18.75 W
1500 lm 100 W 25 W
2250 lm 150 W 37.5 W
3000 lm 200 W 50 W
  • Dimming – Many LED bulbs are not dimmable. Determine if the light fixture you are using requires specific types of replacement bulbs and if those bulbs need to have the dimming feature built in. Generally you’ll pay slightly more for the dimming feature, so if you don’t need it, save some money and buy non-dimmable LED’s.
  • Dimmable vs Warm Dimming – With incandescent lights, when you dim them the color of the light gets warmer (less harsh), a feature known as “warm dimming”. If you are looking for that feature with your replacement LED bulbs, you need to ensure that the fixture you are using will work with LED bulbs and that the bulbs you purchase have the warm dimming feature.
  • Wet or Dry Use – If your fixture/bulb will be subject to moisture (e.g., in a bathroom or outside), be sure to purchase light bulbs (and fixtures) that have been rated to work in a wet environment.
  • Use in a Fully Enclosed Fixture – if the bulb will be used in a fully enclosed light fixture, be sure the replacement bulb is rated for such use. A fully enclosed fixture can expose the bulb to much higher temperatures, and if the bulb isn’t rated for operating in that environment, the life of the bulb could be shortened dramatically.
  • Use in a Motion Sensor fixture – if the bulb is being used in a fixture that contains a motion sensor that automatically turns on the bulb when motion is detected (and shuts off after a period of non-activity), be sure the bulb is rated to work in that fixture.
  • Use in a photocell fixture – an energy saving photocell fixture turns lights on when it gets dark and turns them off when it’s daylight. Check with the manufacturer of the fixture to determine the proper replacement LED bulbs.

Other LED light bulb buying tips:

  • Read the Lighting Facts label – The Energy Labeling Rule requires light bulb manufacturers to give consumers key information in an easy-to-read format. The Lighting Facts label is modeled on the Nutrition Facts label on food packages. It provides shoppers with the information they need to buy the most energy-efficient bulb that meets their needs. The label includes a bulb’s brightness (in lumens), annual energy cost, expected life, light appearance (color), and wattage.
  • Energy Star – When you’ve identified the LED bulbs that meet your requirements as discussed above, select bulbs that are Energy Star qualified. These bulbs have met quality control standards for brightness, color, and energy consumption.

If you still have questions about the proper LED bulbs to buy, contact PKK lighting and we can help you determine which LED light bulbs for sale will work best for the fixture and intended use.

PKK Lighting 2017 Light Bulb Buying Guide – Part 1

Let PKK Lighting find the right Light Bulbs for your Business

PKK Lighting has been selling light bulbs to our commercial customers for many years and we are committed to providing that service well into the future.  As part of our commitment, we want to help educate our customers about the current light bulb market.  We want them to make informed choices about the light bulbs they purchase for their business or organization. This is the first in a series of posts to provide that education.

Buying light bulbs used to be easy.  When your old incandescent bulbs or fluorescent tubes burnt out, you could simply purchase replacements and install them quickly.  However, these bulbs and tubes were (and still are) very energy inefficient and were phased out (for the most part) and replaced.  They were first replaced by CFLs (Compact Fluorescent Lightbulbs) and then by LED (Light Emitting Diode) light bulbs.

Put simply, LEDs are electronic devices that are can be used throughout every space of office buildings, warehouses, grocery/department/convenience stores, and so on.  Manufacturers are adding cameras, sensors and even speakers to some LED fixtures to deliver more than just light.

Types of light bulbs we sell:

  • LED light bulbs: instantly brighten and have color ranges from warm yellow to cool blue and colors in between. Some LEDs are dimmable (be sure to check before you buy) and use less energy than CFLs, thus saving you money on your energy bills. LEDs are typically more expensive but prices continue to drop.
  • Compact Fluorescent Lightbulbs: CFLs use about 75% less energy than the incandescent bulbs they replaced and last 7-10 times longer. Color ranges from warm yellow to cool blue, with colors in between.   They take longer to fully brighten, especially in frigid temperatures.  Most CFLs are not dimmable.  Also, CFLs contain a small amount of mercury, so be sure to recycle appropriately (or let PKK Lighting pick up your spent bulbs).
  • Halogen bulbs: instantly brighten and color is usually a cool white or blue, although you can get a color filter that improves the light but sacrifices some brightness. Halogens have a life span about the same as standard incandescents but use 25-30% less energy.

Regardless of which type of light bulb you need, PKK Lighting can be your one-stop-shop for all your light bulb needs, especially the hard to find light bulbs.  Contact us today and we can help you find the right bulb for the job.

Is it time for your organization or business to upgrade your lighting to LED?

If it’s time for an LED upgrade, what type of fixture should you use, Integrated LED or LED Ready?

Integrated LED Fixtures: These LED fixtures may resemble LED ready fixtures, but the similarities end there.  Integrated LED fixtures come complete with the LED arrays already built into the fixture.  They are designed to provide a specific color and Lumen output and they do not have typical “bulbs” that can be replaced.  Integrated LED fixtures typically last for many years, often a decade or more.  When they do burn out, rather than shopping for a replacement LED bulb, customers will order a new LED array, or module.  However, with the advancements in LED technology we would encourage businesses to evaluate changing out their LED fixtures for more cost effective and updated functionality.

LED Ready fixtures: these fixtures are designed to use LED bulbs and typically are sold without the bulbs.  A primary benefit of the LED ready fixtures is that customers can select the appropriate bulb for their needs as long as the bulb is the right shape, size and wattage.  The initial installation of the fixtures is comparable to the Integrated fixtures, but replacing the bulb when it burns out is easier than replacing the LED array or module on the integrated fixture.

Which type of LED fixture is right for your commercial lighting need?

  1. Is this a new installation or do you have existing fixtures? If you have existing fixtures and they are in need of significant repairs, it might make economic sense to replace them with integrated LED fixtures.
  2. Do the fixtures comply with local building code requirements? Be sure to evaluate whether your new fixtures comply with local building codes before buying them. If you’re not sure, check with a lighting consultant.
  3. What are the lifetime costs for the fixtures? There are many cost factors that enter into the lifetime costs of your LED light fixtures, including the original purchase, installation, ongoing maintenance, and energy costs. Be sure to consider all of the costs before making your decision to buy.
