Replacing Standard Incandescent Light Bulbs with LED Light Bulbs

by Barbara 14. April 2014 07:31

Question about when, where and how to replace incandescent light bulbs with LED bulbs.

Question: "How do I know what bulbs to purchase for replacements? Are there any places that I should not use an LED light bulb? They are certainly more expensive now that stores are selling 60 watt incandescent bulbs, 6 bulbs for $2.00. Thanks. Tim."

Answer: First, as many bloggers have noted, you have to see these bulbs as investments. You won't save hundreds of dollars in a year or two on your electric bill unless you have a huge building that needs all its lights replaced. The savings comes over time and with convenience, the convenience of not having to replace light bulbs in rooms where lamps or ceiling fixtures are on for many hours per day or year. LED stands for "light emitting diodes."

Second, you must make sure that replacement bulbs are dimmable ones for lamps or fixtures that have that feature. And there are no "3 way" bulbs like 50/100/150 available as yet.

Third, there are no 60 watt, 75 watt, etc. bulbs. Every bulb is rated in lumens. Lumens are the amount of light that is produced when a bulb is powered on.

Here is a basic chart that should help:

Incandescent Bulb Wattage             Lumens           LED Bulb Watt Equivalent

25 watt                                          250                4-9 Watts

40 watt                                          450                9-13

60 watt                                          800                13-15

75 watt                                          1100              18-25

100 watt                                        1600              23-30

125 watt                                        2000              22-40

150 watt                                        2600              40-45

Warm white is the preferred color for most people in their homes.  2,700 and 3,500 Kelvin are what you are looking to purchase for home use.

So remember that lumens are what you are looking for, not wattage.

Here is an A19 LED 60 watt equivalent bulb that Safe Home now sells. Equvalent to a 40-60 watt incandescent bulb yet uses only 8 watts of electricity. Epistar LED chip. Warm white color. Short neck. Not dimmable. 3000K. 180 degree beam angle.

As Safe Home continues to add LED bulbs, I'll be adding them to this blog.

Thanks for your question.

Sincerely, Barbara

 

Reflector Style LED Lights for Gradual Replacement of Ceiling Reflector Light Bulbs Reduce Costs for Businesses and Homeowners

Question about the Dimmable BR30 16 Watt LED Short Neck Light Bulbs to replace reflector type ceiling bulbs.

Question: "These light bulbs look a lot like the incandescent lights in our family room ceiling. Changing them is a real pain: requires a very tall ladder. We do like to dim the lights when we watching TV. Is it possible to mix these? The cost is a lot more. We don't like fluorescent bulbs: takes too long to come on and cannot be dimmed. How long should these bulbs last? What could our power savings be?" Thanks. Devin.

Answer: These dimmable LED short neck bulbs resemble the reflector type spot light bulbs. The warm white glow is similar to an incandescent bulb. Each bulb gives essentially the maximum light of a 100 watt bulb when not dimmed yet uses only 16 watts of power. Figure on about 3 years or 50,000 hours of use per bulb. The light is instant on, not like a CFL type bulb. BR30 light bulbs have an expanded reflector: the results are  narrow soft-edged rays and fewer shadows. Use these LED light bulbs for spot lights, flood lights and indoor lighting. 180 degree beam. This is a UL listed light bulb.

LEDs, or light–emitting diodes, are semiconductor devices that produce visible light when an electrical current is passed through them. LEDs are a type of Solid State Lighting (SSL), as are organic light–emitting diodes (OLEDs) and light–emitting polymers (LEPs).

Incandescent bulbs are inexpensive except for the 65 to 100 watts of energy used. (And 100 watt bulbs are hard to find these days.)Here in Iowa the cost per KWH (killawatt hour) is about 7.2 cents, the 12th less expensive in the USA. In the north east the cost can be as high as 18 cents per KWH. The price of LED lights is going down. My son recently began replacing burnt out reflector type bulbs in his ceilings with LED's to lower his power costs over time and to avoid dealing with ladders in rooms with vaulted ceilings. He figured this was less expensive than installing motion sensors to turn off lights in rooms where there was no movement. (His children support the Linn County REC by forgetting to turn off lights when they leave rooms).

We also sell replacement bulbs that look just like incandescent lights in the shape. These LED bulbs use only 8 watts but give the light of a 40-60 watt incandescent bulb. LED Bulb A19 8W, 40-60 Watt Equiv., Warm White, Short Neck. Again figure on 50,000 hours or 3 years continuous use.

Another option to the reflector lights is the COB PAR30 Dimmable LED Bulb, Warm White, 16 W, Short Neck. This has a narrow beam of 60 degrees. Also an Energy Star bulb. COB stands for "Chip on Board." Again UL Listed and Dimmable.

We hope this helps with your decision!
