UVP Display & Bench Series UV Lamps
Right: UVP UVGD-68, a high output shortwave quartz grid Display series lamp (35,793 bytes). Most of these are higher intensity AC powered lamps that incorporate multiple tubes so that the user can work in one or either of two wavelengths of the ultraviolet: 254nm, or 365nm, or 254 and 365nm. Each 225D series lamp will incorporate either two 25 watt tubes or a 254nm quartz grid element. The UVSL-225D is a a multi wavelength ultraviolet lamp that can emit either of two wavelengths of ultraviolet light either 254nm or 365nm illumination. At first glance a UV tube lamp such as the UVL-225D Mineralight® resembles a conventional fluorescent fixture with two or more tubes. The lamp may have a wider profile when it incorporates a grid element. The UVGD-68 differs from the other lamps in this series since its source is a 254nm quartz grid element; the 'G' in it model code indicates this is a grid lamp. Grid lamps are mercury photochemical lamps with glass tubing bent back and forth to form several parallel bars, typically in either a rectangular or square form. They are designed for applications where shortwave 254nm UV energy is needed. The Grid Lamp can be formed so that it concentrates the energy into the specific area required. The grid lamps may require up to five minutes of warm up time to reach full output capacity. Once warmed up then the illumination provided is uniform across the gird; without hot spots or diminished areas of output. And these generate less heat that a comparable coverage tube array. Their comparatively high power output combined with their longevity makes these lamps an idea choice for illuminating displays over a long term, curing epoxies, removing trace amounts of organic contaminants, electronic component cleaning, ozone generators, erasing Eproms and other scientific and environmental uses. Of course these are outstanding for fluorescing minerals:

Most lamps turn on nearly instantaneously, like a household fluorescent lamp, and reach their peak of UV emissivity in seconds. The UVGD-69 reaches its peak intensity after a warm up period of about five minutes.
UVGD-68: 18.5 x 4.75W x 5H inches (470 x 121 x 127mm), weight 10 lbs. (4.6 kg) Left: UVL-225D Mineralight® lamp (16,104 bytes).
Bench XX Series UV Lamps
Right: the UVP XX series 40 watt, 20 watt and 15 watt lamps (32,208 bytes). Left: a UVP XX series lamp pendant orientation (16,679 bytes). The XX series series lamps are AC powered and generally emit at only one wavelength of UV, each lamp is made to emit either 254, 302, or 365nm. However, the XX-15 BLB provides an added feature in that it's standard 365nm longwave filter can be removed by the user and then an optional clear filter (PNB 19-0140-01) can be installed into its place. Since the XX-15 BLB incorporates a BLB then with the clear filter in place the lamp may be used as a conventional black light to support art or entertainment displays. Adding even greater versatility to the series, we offer an optional UV Transmitting Filter (PN 38-0172-02) for the XX-15S that allows it to be used for fluorescence applications. These filters for the XX-15 lamps simply slide on or off. As a greater area of coverage is called for then you can move up from the 15 watt models to the 20 watt, or for even greater areas of coverage select the a 40 watt model. |

Right: two XX-15 BLB lamps, shown with standard and with optional clear covers (29,148 bytes). The XX series lamps are constructed of durable aluminum and finished with an easy to clean and scratch-resistant powder coat. Brackets are included to facilitate suspending the lamp from overhead, or attaching it in a surface mount configuration. Either of the four XX series 15 watt lamps may be attached onto the top of the optional UVP Exposure Stand (PN 18-0062-01) . This 20 inch (50.8cm) long metal stand features an adjustable height shelf so that the distance from lamp to the sample can be set the what is desired. Stability is assured regardless of the sample working height. With the Exposure Stand one can obtain consistent spacings to the subject of the illumination, or if the UV output diminishes then the sample may be moved closer to the XX lamp to compensate and yield the same net results.
The dimensions of these lamps are:
XX-25 Series: 24 x 6 x 4.25 inches (610 x 152 x 108mm), weight 10 lbs. (4.6 kg) XX-40 Series: 49.6 x 6 x 4.25 inches (1260 x 152 x 108mm), weight 20 lbs. (9 kg) Left: Exposure Stand for XX-15 lamps (39,015 bytes).
Company Seven can provide customers with information about lamp longevity upon request. This is usually expressed in terms of continuous hours of operation. While it is usually a simple matter to replace a UV lamp bulb, and we provide instructions with each lamp about how to do so, longevity is of a concern when the lamp is to be used installed into some hard to access location where it may be inconvenient to replace the bulb. So whenever time or labor costs to change a bulb are factors in the decision making process then we recommend:
Company Seven hosts numerous articles and users guides at our UVP Notes & Interesting Articles page and in our Library including:
As amazing as it can be to explore the ultraviolet spectrum, this is not child’s play! For a good overview of working in the UV and explanations of proper precautions consult Ultraviolet Spectrum Primer, the illustrated article by Company Seven explaining the ultraviolet (UV) spectrum as it applies to photographing or imaging objects in the UV and about observing fluorescence, phosphorescence, and tenebrescence. The article explains the different portions UV spectrum including UV-A (long wave), UV-B (mid) and UV-C (short wave). This also goes into a discussion of imaging gear including lenses, films and filters. Then refer to our article Ultraviolet Personal Safety Gear.
Ordering UVP Products
Company Seven stocks some of the more popular UVP lamp and cabinet products, and we accept orders for their other products by numerous means. You can also bring your UVP item to Company Seven for repair, or contact us to obtain user-serviceable items (bulbs, grids, etc.). The ways by which you may order products or parts are outlined at
Company Seven has not become convinced that on-line ordering is always beneficial for the customer, particularly when making a more complicated choice. While on-line ordering certainly is convenient and time effective for the merchant since they do not have to spend time with the customer, the customer is not always making the best choices when buying solely after reading what may be "propaganda" on line. The best ways to make the better choices are to either visit our showroom, or telephone 301-953-2000. This way you can obtain prompt and competent concise assistance which will address your particular needs and concerns.

225D Mineralight® and UVGD Mineralight® Lamps
The dimensions of these lamps are:
These UV lamps too are engineered to provide UV coverage over a comparatively wider area than that provided by the High Intensity series, the 
The XX series 40 watt lamps provide the greatest area of UV coverage of all the lamps made by UVP. This series are engineered to provide a good balance of output and cost. These are well suited for use in protected industrial or research environments such as at the laboratory bench top pointing down, or pointed up in air handling areas where airborne bacteria may be a concern. These are designed for use when installed into a cabinet, attached to an optional Exposure Stand, or suspended over the object to be illuminated.
WARNING Infrared and ultraviolet wavelengths are invisible to the human eye yet these electromagnetic waves bear energy and other information. So any structure that absorbs the light can be damaged by this energy; note how sunlight exposure tans the skin while prolonged exposure fades or breaks down materials. The photons of shorter wavelength carry greater energy therefore, these have the greater potential for causing biological damage. These wavelengths can penetrate the eye or skin cells and can produce heating and energy related biological changes that will modify or destroy cellular DNA; this is among the reasons why some UV light sources are used for germicidal (sterilizing) applications.
