Product Description
Full-spectrum 20-watt fluorescent bulb imitates natural sunlight. Incandescent lamps provide light, but they don't provide the same healthy, natural light of the sun. The Evolution 20-Watt CF Full-Spectrum Bulb simulates the full-spectrum natural outdoor sunlight to provide a healthier indoor environment while also saving energy. The full-spectrum bulb also lasts about 10 times longer than standard incandescent bulbs. The Evolution 20-Watt CF Full-Spectrum Bulb is a medium screw-base lamp designed to replace incandescent lights in table lamps, recessed down lights, porcelain keyless fixtures, and anywhere else you need energy saving possibilities of a fluorescent lamp. Natural light from the sun and sky has a balanced spectrum, rendering colors perfectly. Most artificial bulbs emit light rays in a narrow scope of the visual spectrum. This full-spectrum bulb helps people see better, feel better and creates a healthy indoor environment. The 20-Watt CF Full-Spectrum Bulb equals the light output of a standard 75-watt incandescent lamp.

Great bulbs, but fragile and poorly documented,
By
This review is from: Evolution 20 Watt CF Full Spectrum Fluorescent Bulb
These bulbs produce nice clean full-spectrum light. At first, the difference between the light of the conventional bulbs I replaced with these was strange. But I quickly became accustomed to it; it is much better for doing things in, whether it be brushing your teeth, using a computer or reading. But that wasn't my motivation for purchasing them. I wanted energy efficient bulbs which are long-lived. The bulbs give off much less heat than a regular one. I am able to use the equivalent of a 75 watt conventional bulb in lamps with paper covers. How much more energy efficient and long-lived they are, I do not know yet. They were recommended by Coop America for energy efficient lighting. So for now, I'm taking their word these truly are long-lived, energy efficient bulbs.Consider this though, as should the distributor if they want to successfully retain customers. The bulb itself is very fragile compared to a conventional bulb. When screwing these ones in, you *must* do it carefully manipulating only the base. Otherwise the bulb will break. I ruined one bulb this way. Also these bulbs are not compatible with dimmer switches. I ruined another using it with a dimmer switch. The distributor sells some that are compatible with dimmer switches. The main problem, which resulted in the ruin of two expensive bulbs, is these bulbs came arrived with no documentation. This led me to expect they could be handled and used like regular bulbs. As I've mentioned, they can't. As for not being compatible with dimming switches, there was a warning on the bases of the bulbs in lettering so small I didn't notice it until after I had ruined the bulb and looked at it more closely. These bulbs are relatively expensive. Although the seller kindly offered to replace the ruined bulbs with the implicit condition I retract my negative review, I felt ethically bound to refuse their offer. So here is the result. Hopefully the seller will learn from this, so they don't have to offer to replace bulbs.

Great bulb,

This review is from: Evolution 20 Watt CF Full Spectrum Fluorescent Bulb
I just got four of these things, and installed them in a few choice locations in my apartment. Lets just say that after 5 minutes, I've gone around and counted all of my other incandescent bulb holders, and will be replacing all of them with these!These things are great. I love the full spectrum light - you'll immediately notice the difference. After just a few minutes, I now hate all my old standard incandescent lighting - the yellowish "hue" they give off doesn't hold a candle to the pure light that these full-spectrum compact fluorescents put out. And I should add that I'd been using "higher-end" GE Reveal incandescent bulbs .. but these full spectrum compact fluorescents put them to shame. Not to mention that they'll last 10x as long - I used to hate having to make sure I had a constant stock of GE Reveal bulbs, as they don't last very long at all. And on top of all that, it feels good that I'm now entering the ranks of the countless eco-friendly, responsible citizens already out there who have already switched to more power-friendly lighting. There are some caveats though to these bulbs - there's a big warning on them about not using them in totally enclosed recessed lighting fixtures, and they are also not for use with dimmer switches. When I installed them, I did so carefully, making sure I twisted them in from the base (which is large and easy to do). Give these things a try. You won't be disappointed.

Great but cannot use in enclosed fixtures,
By W. Chef "WC" (California, United States) - See all my reviews
This review is from: Evolution 20 Watt CF Full Spectrum Fluorescent Bulb
The trouble with fluourescent bulbs, which is never mentioned in the packaging, is that they are not designed for enclosed fixtures such as are commonly installed in many homes. So if you have a glass enclosure around the bulb, it will burn out way sooner due to the higher operating temperatures in such an environment. It should be illegal to sell these without a plain warning to that effect. However, if used properly, these are really great bulbs and will last a long time.
