What’s the Difference Between Incandescent and LED Light Bulbs March 5, 2015

Low Cost A19Walk down any super store lighting isle, and you will notice that LED ( Light Emitting Diode) light bulbs are gaining in popularity. There is a plethora of styles, light colors, dimmable, non-dimmable – you name it and there is a LED light bulb to meet the need.  So what’s the difference, besides price, between the old technology of incandescent light bulbs and the ever-improving technology of LED lighting?

Incandescent light bulbs, or lamps as they are known in the lighting industry, are produced by blowing hot glass into molds.  When cooled, the glass is coated with a diffusing material. A very thin, tungsten filament is placed inside, and a base is added.  Electric current is used to heat the filament, which generates the light. Although people like the light generated, only about 10% of the energy used results in visible light. The remaining energy seems to be given off as heat.

LED light sources are gaining popularity simply because they use less energy to produce quality, long-lasting light. They are made differently than incandescents, and are suprisingly stong, and able to be assembled in many shapes. Powered by a light-emitting semiconductor, the lights are also available in a variety of color.

Light is emitted through a diode – a device which allows current to flow in only one direction. Light is created when the energy flowing in to a chip is released. The color of the light depends on the ingredients and processes used.

LEDs also have advantages over other lights, including:

  • High energy efficiency.  Up to 85% more efficient than incandescents
  • Low heat
  • Low voltage and current requirements
  • High levels of brightness
  • Very reliable.  Resistant to shock and vibration
  • Long life. 20,000 to 50,000 hours.
  • No UV rays 

Lighting manufacturers have switched their focus to LED replacement lamps and fixtures. I can’t wait to see what comes next.  I’m waiting for a three-way version. Use coupon code Take10 for 10% off during check-out for quality TCP LED lighting at www.bowmnlamps.com.

What’s the Difference Between a PAR and a BR Floodlight. February 27, 2015

Ever ask those age old questions: What is a PAR floodlight?  And, what is a BR floodlight? No need to ask again.  You can stop scratching your head, because here we will answer what the difference is between PAR and BR floodlights – also known as lamps in lighting circles.

PAR, and BR, mean more than just strange animal sounds. PAR stands for Parabolic Aluminum Reflector, while BR staPAR38nds for bulge reflector.  The number after the letters refers to the diameter based on 1/8 of an inch. To find the size of a PAR38, you multiply 1/8 x38, which equals 4.75 inches in diameter. A PAR30 would be 1/8 x 30, which equals 3.75 inches in diameter. And the other popular PAR20 diameter would be 1/8 x20, which equals 2.5 inches.  The same applies to the BR series, with the popular diameter sizes being BR40 (1/8 x 40 = 5 inches, BR30 (1/8 x 30 = 3.75) inches and BR20 (1/8 x 20 = 2.50 inches).

So what’s the difference between PAR Floodlights and BR floodlight? PAR floodlighs have a flat lens.  Each is designed to direct the light for various intentions.  For instance, TCP PAR floodlights may be purchased with a wide 40 degree beam spread, a narrow 25 degree beam spread, or a spotlight with 15 degree beam spread.  They are perfect for demanding light applications like hiElite BR40gh-end retail and restaurants, where certain items or locations are highlighted.  Want to highlight a large area of a room? Use the wide beam.  Want to highlight Uncle George’s portrait, try the narrow beam. And what about that diamond ring in a display case? Use a spotlight.  BR floodlights have a curved lens. With a beam spread of 120 degrees, BR floodlights illuminate large areas with smooth, attractive light. You know, like a living room or lobby.

Let’s focus on the latest technology, LED.  Both PAR and BR lamps may be used indoors or out, usually in canned or recessed fixtures.  Use outside requires they either be designated for wet locations, or restricted to areas where they are protected from the elements. ( A roof overhange works quite nicely.)   PAR and BR lamps also come in a variety of light colors, from the 2400K warm tones – like a standard light bulb – up to 5000K daylight white. So sit back and think where you would use a PAR or BR light. Dimmability is not a given. So please remember to select a dimmable or non dimmable floodlight to meet your needs.

If you are interested in purchasing an LED PAR light, bowmanlamps.com has a great selection here.  Or checkout the BR series here. My favorite is the TCP warm white dimmable BR30.  And, it’s Energy Star approved.  Use coupon code Take10 during check out for 10% off these or any other lighting items at bowmanlamps.com.

Need more light, but trying to conserve energy?  LED replacement lighting has been improving over the past few year. Gone are the complaints of “LED lighting is too blue! Contemporary LED lighting allows for warm lighting on up through daylight white.  One of the more popular, and prolific, items has been 40 Watt and 60 Watt LED replacement light bulbs.

100 Watt Replacement LED Lightbulb

 But the greater light of 75 Watt or 100 Watt replacement LED light bulbs has been slower to achieve.

Buying an A-Lamp LED Light Bulb? Consider These Four Items March 17, 2014

Posted by bowmanlamps in LED lighting.
add a comment

Have you ever fealt frustrated  when buying a light bulb?  What used to be simple has become a bit complicated. Take heart.  It’s really not that complicated.

For simplicity sake, let’s narrow things down to four things to consider when buying an LED A-lamp, the standard light bulb shape which we all know and love. Here are things to consider:

1. Light disribution – A standard incandescent light bulb (or lamp as it is known in the lighting industry) gives off light in all directions. LED lamps are more limited, sending out light in one direction. A good general purpose LED gives off light at about 230 degrees. That would do best in a fixture with a backing.  A good omni-directional lamp expands the light beam to 270 degrees – which would do best in a table lamp or fixture without a backing.

2. How much light – Most LED A-bulbs on the market today use seven Watts to replace a 40-Watt incandescent, or about 10 Watts to replace a 60 Watt incandescent. There are a few manufacturers producing a 100 Watt equivalent, but I would wait a little longer until the technology is tried and true. When comparing LED A-lamps, you may also want to consider the lumens.  It is a more accurate rendition of light output. A lamp which uses 7 Watts to replace a 40 Watt incandescent will generate between 450 to 500 lumens.  A lamp which uses 10 Watts to replace a 60 Watt incandescent will generate between 800 and 900 lumens. The information is generally readily available on the box.

3. Light Color – There are many variations of white available in today’s lighting.  The selection can be based on room color, the amount of lights, available daylight, and just plain preference. In genera, the lower the Kelvin number the more yellow the light color, while the higher the number, the more white a bulb gets, even into a blue range.  Lamps marked 2700K are considered warm white and most resemble a standard incandescent. A 3000K lamps is also considered a warm white, but most resembles the white color of a halogen lamp.  3500K and 4100K are considered a cool or bright white and are often seen in office situations. Daylight white, 5000K to 6500K, is considered most like the noonday sun. Some people prefere this color for reading, small handwork, and even growing plants. But when all is said and done, it comes down to personal preference. I’ve had husbands proudly light the kitchen with 5000K daylight bulbs, only to have their wives state “it looks like we should be disecting frogs in here!”

4. Dimmable or Non-dimmable?  Perhaps the biggest part of this question is that it has to be considered at all.  Incandescents are fully dimmable. However LEDs are manufactured as dimmable or non-dimmable. And while a dimmable lamp can be used in a non-dimmable socket, a non-dimmable lamp  is limited to non-dimming sockets.  Most dimmable LEDs work well with a basic, non-illuminated dimmer. However there are dimmers designed just for LED use.

As mentioned earlier, most of these items depend on preference. If you are planning to retrofit a room or more, please consider purchasing a few samples before investing in LED lighting. There are many variations available, so give a few a try.

A light bulb is a light bulb – right? Not in today’s lighting market.  There are enough light bulb styles to make a light bulb consumer dizzy. The chart below helps sort out the differences between the three main types of light bulbs, LED, Comapct Fluorescent (CFL) and incandescent.

Here’s Some of the Ways in Which LED, CFL, and Incandescent Light Bulbs Vary
  LED CFL Incandescent
Cost Expensive Moderate Cheap
Replacement / 50,000 Hrs 1 5 42
Avg. Life 50,000 HRS 8,000 HRS 1,200 HRS
Light Output per 800 Lumens 6 to 8 Watts 13 to 15 Watts 60 Watts
Start Up Instant On Slight Delay Instant On
Dimmable Yes If Designated Dimmable Yes if Designated Dimmable Yes
Durability Tough Fragile Fragile
On-off Cycling No Effect Shortens Life Minimal Effect
Heat Given Off Low 3 BTU/HR Medium            30 BTU/HR High 85 BTU/HR
Sensitive to Cold No Yes Some
Mercury Enclosed No Yes (Minimal) No

A Dependable Line of LED Lamps

LED BR30 FloodlightConsidering the bits of information above, one of the best lines of LED light bulbs I’ve found is the TCP Dimmable Floodlight series. They offer smooth, uniform dimming from 100% to 0.5% with consistent color. The lamps exceed all industry standards. Highly efficient LEDs and driver allow for long life, exceeding 25000 hours. UL listed for damp locations. Ideal for use in recessed cans, track lights, display lights and outdoor fixtures (protected from the elements).

I have these in my family room.  They give off good dim well.   Visitors don’t even notice they are LED flood lights. You may read about them here.

Awesome Dimming CFL Light Bulbs

TCP TruDim CFL Light Bulb I also use the TCP line of Pro Series TruDim dimmable CFL light bulbs in my kitchen.  With uniform dimming from 100% down to 2% and digital technology for faster run-up time, they beat other CFL dimmables.  Most start flickering when dimmed down past 20%. Take a look here.  They are available in spiral, R20, R30, R40 floodlights, A-lamp and G25 or G40 globe shapes.

As for Incandescents….

There are two incandescent light bulbs left in my house.  One in the almost-inaccessible attic which was put there when we moved in 23 years ago.  I think it’s been turned on once or twice. The other is in our ancient garage door opener.  I’ve found LED light bulbs and CFL lamps do not work there, probably because of radio frequencey interference. Maybe your opener is different.

I’ve found CFL light bulbs to be very accomodating in my home.  And with the exception of an occasional dud, long lasting – to the point I wish they would fail so I can replace them with the newer versions of LED light bulbs.

There is a lot of change taking place in the world of lighting, and restaurant owners / managers should consider a lighting update.  The end result will be a more inviting space and lower energy bills.

Here are a few areas which you may want to refurbish with the latest energy-saving LED and CFL (compact fluorescent) light bulbs.  Both have come a long way since they entered the market, and it is easy to say selecting the right light bulbs can enhance both dining and work areas.  Let’s consider:

Entrance Lighting: There is no need to explain the need for a well lit, inviting entrance.  TCP LED wall packs provide long lasting, low-mainenance, pleasing illumination. And, they have excellent light output and optimal energy efficiency.

Chandelier Lighting: Add a little style with energy efficiency.  TCP LED deco lamps are fully dimmable and beautifully designed for mood lighting. Choose from standard medium base or small candelabra base.

Spot Lighting: TCP LED PAR floodlights come in narrow flood, wide flood and spot options to highlight the most attractive areas of your restaurant.

Bar Lighting: Help set the mood with TCP BR floodlighting.  Ideal for downlighting or track lighting, the lamps are fully dimmanble and long-lasting – perfect for those hard-to-reach areas.

Kitchen Lighting: Food prep areas and glass lighting don’t mix well. Get optimum light with shatter proof lamps.  TCP InstaBright with ArmorCoat covered CFL bulbs have a protective layer that keeps bulb contents intact in case of breakage – perfect for food-prep areas.  ArmRLux T8 lamps have a similar protective coating.

General Lighting: TCP LED 2 x 2 fixtures are recommended for any place a lot of light is needed.  Brightly light kitchen work areas, walk-in coolers, storage areas and starewells.

Restroom Lighting: Restrooms should be comfortable and well lit. TruStart SpringLamps offer instant brightness, and they work with occupancy sensors.   Another option is the Fresh2 odor ending CFL.  Keep your restrooms smelling fresh.

Why Wait? Get Light Fast with Quick Starting TCP TruStart CFL Light Bulbs August 16, 2012

Posted by bowmanlamps in Uncategorized.

TCP TruStart are the fastest lighting CFL light bulbs availableA common complaint about compact fluorescent light bulbs (CFL) is slow start time – turn a CFL on then wait a minute or two before it warms up enough to use.

Now, with TCP Inc.’s new TruStart series CFL, there is no need to flick the switch and wait. A small processor chip is incorporated in the ballast of TruStart lamps (or light bulbs), which greatly shortens the warm up time. Within a second or two, the lights snap on to a useable level, then quickly warm up to full brightness. You get useful light in seconds and full brightness in a half minute, which is twice as fast as regular CFLs.

The programmed start also allows the the lamps to last twice as long. A standard CFL is rated for 10,000 hours, while the TruStart is rated for 20,000 hours. And, TruStarts may be used with most occupancy sensors and other lighting controls.  

Use these little cuties in table lamps, wall sconces, recessed cans, chandeliers and ceiling fixtures. UL approved for damp locations, meaning they can be used outdoors in weather approved fixtures. And, the bulbs are backed by a three year guarantee.

Choose from:

  • 23 Watt (100 Watt incandescent equivalent)
  • 18 Watt (75 Watt incandescent equivalent)
  • 14 Watt (60 Watt incandescent equivalent)
  • 9 Watt (40 Watt incandescent equivalent)

All are availble in various light colors:

  • Warm white 2700K and 3000K,
  • Cool white / bright white 3500K and 4100K,
  • and Daylight white 5000K and 6500K.

Simply put, TruStart CFL light bulbs have the longest life of any bulb in the market, while achieving full brightness in record time.

The full line of TCP TruStart CFL light bulbs is available at bowmanlamps.com.
