LED Lighting

Off-Grid or just want to save money? LED’s have finally come of age. They arrived with performance, long life and compatibility with incandescent fixtures compared to the current CFL’s.

I’ve worked with LED’s for use in the medical devices we designed and I can say the last seven years have seen dramatic improvements in LED technology. I prefer LED’s over CFL’s because of their long working life and lower operating watts.

Our Gov should have waited with the CFL’s and pushed for the development of LED’s, but hey, what would you expect from them.

Yesterday, I was at Sam’s Club and in the isle they had several skids loaded with GE, LED 60-watt equivalent bulbs. I stopped, read the packaging and bought 3, 6-packs of them. The price, $9.99 for six LED’s or $1.66 each. Each is estimated to last 13.9 years at 3 hours a day of use.

Their reduced size now allows them to fit in existing table lamps, fixtures, etc. The light they emit is smooth even light, no shadowy gray areas or doughnut holes. They completely replicate the light and output of an incandescent 60-watt bulb but instead of using 60 watts they use only 9 watts

 LED vs 100-watt incandescent.


  1. So lumens are exactly the same? I must say I do like the output of light from a good bulb in a lamp. I bought a couple LED bulbs a few years back and I was not impressed with the light output. I was hoping they'd get better after some time so it sounds like they have?

    1. The regulated lumens for a 60 watt incandescent bulb is required to produce 800 lumens minimum. These LED's are rated at 800 lumens. If I had access to the light metering equipment when I was working I could verify to output. However when I replaced the 60 watt bulbs in the house we could not tell an illumination difference between the incandescent and the LED's.
      If you like an old bulbs soft white light you will like these.

  2. Something to think about. I have had some of the CFL's burn out just as fast as the Edison light bulb..

    1. I have the same problem with CFL's, I have 8 of them in my kitchen ceiling can/fixtures and they fail on average after 18 months. I do date them when I install them so I know how long they've been in use.

  3. Mike,

    We'll need to check these bulbs out, thanks for the info.
