CAP UV-C and UV Plus products are equipped with high quality, high-output U.S.-made lamps for optimum performance and reliability. The hard quartz lamps are rated for at least 9,000 hours (1 year) when installed and used in accordance with the operating manual. Lamps may last much longer in some situations, but annual lamp replacement is recommended since the UV output of any lamp typically starts to drop off after about 9,000 hours. On/off lamp cycling will reduce lamp life.

CaluTech products use UV-C germicidal lamps which operate at a wavelength of 253.7 nanometers and can last as long as 3 years. Each lamp is under warranty for 1 year, and 36W replacements are only $22.99 each, not $40 or $80 each like other companies (we don't mark them up). Replacement 18W lamps are $22.49. It is a very cost effective UV air purifier. The lamps are known to operate for as long as 3 years. We recommend annual changes of the UV lamps for maximum ultraviolet air sterilization.

Several safety measures protect service technicians and homeowners from eye or skin UV exposure, including a lamp shutoff switch, and a sight glass for safe and easy lamp inspection. A protective cover with a safety interlock switch immediately deactivates the lamp before the service technician or homeowner can access or service the unit. The effectiveness of germicidal UV-C is limited once molds, which are more resistant to UV energy than airborne bacteria, have already formed on surfaces.

No. The risks are approximately equal. For some time it was hoped that UV lamps could be made safer by making more use of long-wavelength (UV-A) radiation. That type of radiation is much less carcinogenic than the shorter-wavelength UV-B radiation, but one needs more UV-A than UV-B for acquiring a tan.

It's very common for customers to think our UV lamps are not efficient like competitors because they are low priced, but the fact is they are more powerful than most UV-C germicidal lamp products used in other UV air purifier systems. Plain and simple, we don't mark them up. You can find our same style lamp used in our UV air purifier at a competitor site for $45 each, and we even found another for $107 each, that's just ridiculous. The $22.

Overall, people spend 90% of their time indoors, in a "closed" environment with little or no exchange of outside air. Such an environment can become a breeding ground for potentially harmful pathogens, and in high numbers, can prove hazardous to human health.

UV Plus is a penetrating wood stain and oil finish that beautifies and protects exterior wood, providing a natural appearance. It is ideal for use on cedar, pine and redwood and comes in a variety of tones and semi-transparent colors. UV Plus contains fungicides and UV absorbers of the highest quality. It does not form a surface film when properly applied and is not subject to peeling and flaking. To recoat, just clean and/or brighten the wood surface and reapply UV Plus.

Since UV readings vary dependent upon meter brand, lamp brand, ballasts, voltage, age, and acrylic transmission, lamps need to be measured when new to determine what they should read in OEM equipment. Since it takes a "burn in" periods for tanning lamps to evenly distribute the gases and mercury, you may want to wait until you have 10 or more hours on the lamps before taking your first reading. Take readings from 2 or 3 different lamps in the same manner.

Lamp manufacturers generally strive to minimize ultraviolet light (UV) radiation in all lamps used in general lighting applications. The amount of UV produced by standard fluorescent lamps, such as those in your office, home, or school, is not hazardous and does not pose a major health concern. In fact, a paper by the National Electrical Manufacturers Association (NEMA) explores this subject in more detail.

C-Cap is a hub designed to provide a venue for private investors ("angels") and entrepreneurs to communicate, and for entrepreneurs to find the other resources they need to succeed. C-Cap was formed in response to the growing need for an efficient deal flow between investors and emerging companies with high growth potential. C-Cap is operated by The Circuit Cincinnati's Digital Connection, which is the Cincinnati region's trade association for information technology companies.

Under normal home phototherapy usage, the bulbs have a useful life of at least three to five years, and as many as ten years. Fluorescent bulbs gradually lose power over time so that over many years, treatment times are perhaps double that of new bulbs, but the type of light remains consistent (has nearly the same relative spectroradiometric profile). The decision to replace bulbs is therefore only a matter of the patient's tolerance of longer treatment times.

New decks should weather six to eight weeks before applying UV Plus for Hardwood Decks. After weathering, the wood should be cleaned. The wood needs to weather sufficiently to allow the pores to open up to accept the stain. Failure to do so may cause premature failure and possible surface sheen problems.

Redwood decks should weather six to eight weeks minimum before applying UV Plus. The wood needs to weather sufficiently to allow the pores to open up to accept the stain. Failure to do so will cause premature failure and possible surface sheen problems.
