A light bulb that helps allergy sufferers and people who own smelly dogs? O•ZONELite™, developed by David deMartino, a lighting manufacturer, is said to destroy bacteria and odors. The bulb is coated outside with titanium dioxide; subjected to light and heat, the manufacturer said, it vaporizes and kills airborne bacteria, mold spores and micro-organisms that cause odors. The O•ZONELite™ is coil-shaped; a model using 23 watts of power gives as much light as a 100-watt incandescent bulb and fits any fixture or table lamp. It is $39.95 from www.ozonelite.com; (800) 494-8292.
