Fresh2 Fluorescent Bulbs: Light and Air
by on 02.16.05
Until LED lighting comes down from its stratospheric pricepoint, compact fluorescents are the next best thing. Their color is getting very respectable, and the newer models virtually eliminate flicker of any kind. Plus, you get ages of low-watt light without having to change the bulbs. What more could you possibly want from these little powerhouses? Interesting you should ask -- How about cleaner air?...
The Fresh2 CF light bulb is a new twist on the standard coil lamp. In addition to kicking out 23 watts of efficient light, the surface of the lamp is coated with a titanium dioxide nano-layer that neutralizes odors in your home. The dioxide layer uses UV light, which is produced by all fluorescents, to ionize air around the lamp. As this ionized air circulates the room, it attacks odor causing molecules, knocking them out of commission. Voila! you get a brighter, fresher house without any chemicals at all, and at a price you can't beat. Fresh2 bulbs are 2 for $20.00 US if you order directly from their webspace.

How does one "virtually eliminate flicker of any kind?"
I have been looking for better bulbs, and you can bet I'll be buying some of these.
"How does one virtually eliminate flicker of any kind?"
Simple. The annoying, buzzing, flickering fluorescent lights we all grew up with in school (remember trying to take the SAT and hearing that loud hum) used magnetic ballasts which simply transmitted the 60 Hz frequency of the utility-supplied power.
Today's electronic ballasts convert 60 Hz AC into DC, then back into AC, but at a much higher frequency, into the RF range, 20 kHz or greater. This totally eliminates (humanly-perceptible) flicker, in addition to boosting energy efficiency.
If you have put off trying compact fluorescents due to lifelong dread of the word "fluorescent", don't!! You will be surprised, and you will cut your coal-powerplant emissions by 75%!
Titanium dioixide is a very interesting material. It can also be photovoltaic.
Waxyak,
Thanks for the comment. It's great when our readers add to the conversation and give some further depth to our posts.
