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.
