Ugly and causes sleep problems 10/14/2012
This review is from: Collection LED A19 6 Watt Light Bulb, Daylight
It's an LED lamp, so it will be efficient and last a while. The price is acceptable for you and me.
The color rendering index (CRI) or "color accuracy" is absolutely atrocious. With 70 CRI, you can expect every red color to look brown-grey with this bulb. This is stressful on your eyes and it is unpleasant as a lighting solution. Real LEDs do not have 70 CRI. They have much higher CRI (85 to 100). These are cheapos. Avoid them.
Also, the color temperature, "daylight," (6500 Kelvin) is NOT good for your mental health. If you use these bulbs at night, you will have sleep problems, because this bulb fools your brain into thinking that the sun is still out, even when it's 9 or 10 pm at night. Now, imagine this bulb staying on while you do homework until 1 AM. You are ruining your circadian rhythms. Do not abuse your Suprachiasmatic Nucleus (SCN). You won't like what happens. Believe me. I can't get to sleep before 2 or 4 AM any more.
