Great Energy Savers with Fantastic Full Spectrum Light, December 1, 2006
(Note the wrong product image is shown as of 12/1/2006. The picture should show a compact fluorescent twist bulb instead of the traditional fluorescent tube).
In my quest to locate superior energy-efficient products, I purchased and tested over thirty different types of compact fluorescent bulbs. In terms of light quality, the Feit Daylight 100 is the best. As you may already know, compact fluorescent bulbs are roughly four times as efficient as traditional incandescent light bulbs. This provides a electrical cost saving of about $75 over the bulb's lifetime. With the Feit Daylight bulbs, there is an additional benefit of having superior light quality that replicates natural sunlight.
Whether you need a boost in the morning or merely want to enjoy more natural light, these bulbs can help. In one application, I have two of these bulbs in a glass fixture in my bathroom. It is really quite invigorating to have white light surround you, refracting through the water droplets as you shower. This is a great setup for those of us who do not consider ourselves "morning persons".
In comparison to other full-spectrum compact fluorescent lights, these bulbs appear to have superior brightness and color quality. While this is subjective, I found them more appealing than bulbs by Lights of America, GE, and Longstar. Moreover, there is no flicker or audible buzzing noticeable on other lights. The only superior full-spectrum light source that I have personally used is the Sunray Sunbox (see review). However, this is a $400 light box.
The benefits of these bulbs over incandescent bulbs are myriad. Incandescent bulbs emit 90% of their energy in the IR (infrared) region that does not aid human vision. Compact fluorescent bulbs produce more light energy in the visible spectrum and generate far less waste heat in the process.
The greater efficiency leads to a tremendous direct cost savings. The savings is further amplified when taking into account the decreased load on air conditioning. The lower heat generation also means it is easier to place these bulbs in confined spaces such as recessed lighting and lamps with small shades. Also, there is less worry about blown fuses when using a microwave, vacuum or hairdryer as the power consumption is almost negligible.
If you are interested in saving money and the environment, please replace all of your bulbs with compact fluorescent bulbs. If you also want bright white light to enhance your environment, then the Feit Daylight 100 is the way to go.

Tremendous cost savings (about $75 per bulb over its lifetime)
Fantastic color quality
Allows for brighter light in confined spaces
Longevity (10x as long as incandescent bulbs)
Additional energy savings through reduced load on air conditioning
Less chance of blown fuses

Incredibly crisp light, March 1, 2009
When I first got one of these lights about 18 months ago, I just hated it: I felt like I was being beamed into some UFO by freakishly white light. But then I started using it. I'm hooked.
Right off the bat, you'll appreciate that this light turns on extremely fast (probably 80% brightness the moment you hit the switch). Though the blue light, as I mentioned, takes some getting used to, you'll find that it's much easier to read by. Old yellow incandescents just feel yellow and unpleasant now. The 23-watt one here is a little bit bright for a place where the light source is directly exposed (like a spotlight lamp), so you may want to get the 18-watt for those; for a place where the light source is shaded, this is a great choice.

Good for lamps., January 27, 2009
This worked well in our lamps but was too large to fit in the covered overhead fixtures. Produces a clean blue light thats prettier than an incandescent bulb with a similar brightness to a 60 watt bulb.
