Tools and Hardware Reviews of Evolution 25 Watt CF Full Spectrum Fluorescent Bulb
Customer Review: Great bulbs, but fragile and poorly documented
Summary: 4 Stars
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.
Customer Review: good product for the moneky
Summary: 4 Stars
Bulb works as advertised. I bought it to use with my tomato plants until I can put them outside in May. The full spectrum light has allowed my plant to grow (albeit a bit slowly) and prosper. The best thing about this bulb is it fits in any standard light socket (like I found an old desk lamp) and works well. I set a timer so it is on for about l6 hours a day (that's what is recommended for fruiting plants). Anyway, it serves the purpose I bought it for and it was so much cheaper than buying a full spectrum lamp. It only uses 25 watts, so it hasn't caused my electrical bill to rise (at least I have not noticed an increase).
