UVP Portable & -26P Series Rechargeable Lamps
Portable UV The UVP Portable series (ML-49, UVG-47, and UVGL-48) lamps are battery powered lamps that incorporate one 6 watt ultraviolet (UV) illumination tube or a black light bulbs (BLB) so that the user can work in any one wavelength of the ultraviolet that are most popular for applications in the field: 254nm, or 365nm. The UVGL-48 incorporates a single tube too but that provides the choice of either 254 and 365nm output. In addition to the UV each lamp also incorporates a conventional white light flashlight. Right: UVP hand-held Portable series lamp, this resembles both the ML-49 and UVGL-47 models (23,553 bytes). The chassis of each lamp incorporates a distinctive curved carrying handle. This ergonomic device makes it comfortable to walk with the lamp hand-held, either holding it high on the handle and directing the ultraviolet beam ahead or holding the lamp handle lower and directing the ultraviolet beam down towards the ground. The toggle switch to control the lamp settings ('UV', 'OFF', or 'White' for the flashlight) is conveniently located on the sloping panel at the top rear of the lamp. The ML-49 and the UVG-47 models incorporate either the single 6 watt tube or one black light bulb. The similar UVGL-48, illustrated above right at center, is a multi wavelength Split-tube ultraviolet lamp that can emit either of two wavelengths of ultraviolet light. The tube in this lamp is made so that while the bulb is powered on, the upper half fluoresces to provide 254nm output while the lower half of the tube will fluoresce to provide 365nm illumination. The lamp filter panel is partitioned into two panes by a blocking aluminum cover that the user can position over either portion of the filter element, this slides back and forth or can be removed and snapped back into place. Sliding the cover up or down blocks either source to allow only one wavelength to pass or the cover can be removed when you want both 254nm and 365nm illumination. The cover can be stored in the battery compartment. To replace the bulb of a Split Tube model lamp one need order only the one since these lamps do not rely on a separate tube for each wavelength. Each Mini UV lamp is powered by two optional 6 volt 'Spring Top' lantern batteries operating in series to provide 12 volt. These batteries should either be conventional zinc-carbon, alkaline or lithium providing 6 volts or it could be a sealed lead acid rechargeable battery:
Above: examples of 6 volt lantern batteries, the rechargeable battery is to the far right (60,145 bytes).
The molded plastic bodies of this series share the common dimensions of: 9.5 x 2.8W x 9.4H inches (241 x 71 x 239mm), and weighs about 4 lbs (1.8 kg). Each of the two batteries alone weigh about 2 lbs. (1.4 kg) and these account for most of the working weight of a complete lamp.

Rechargeable -26P Series UV
The UVP Rechargeable -26P series lamps are 12 volt rechargeable battery powered lamps that incorporate two 6 watt ultraviolet (UV) illumination tubes. The single wavelength models UVL-26P (365nm) and UVS-26P (254nm) give the user the choice of operating in a power conserving 6 watt mode with one tube on, or in 12 watt mode with both tubes illuminated simultaneously. The model UVS-26P has two shortwave tubes placed behind long-life "UVG" ultraviolet transmitting filters. The UVL-26P has two longwave self-filtering tubes. Right: UVP rechargeable model UVSL-26P UV lamp (52,755 bytes). The multi-wavelength UVSL-26P has one shortwave tube placed behind a long-life "UVG" UV transmitting filter and one longwave tube behind UVP's special longwave UV filter. The UVSL-26P permits the user to work in either 254nm or 365nm wavelength tube in 6 watt mode, or by selecting two tubes on the slide switch you may operate both UV spectrums simultaneously. These lamps incorporates two carrying handles in an arrangement that makes it comfortable to walk with the lamp hand-held, either holding it by the top handle and directing the ultraviolet beam ahead or holding the lamp by the flexible strap handle at the rear and directing the ultraviolet beam down towards the ground. All the controls are easy to access and are readily distinguished even in the dark. The black rubber-covered push button switch (lust left of the top handle) turns the unit on or off. The side mounted toggle switch determines the choice of wavelength, while the small slide switch determines whether one or both bulbs will be on simultaneously. The chassis of each lamp is a bit more compact than that of the above Portable series, hence these are a bit better suited for travelers who must fly to their destinations though care should be taken when packing the lamp to protect the toggle switch. Each 26P series UV lamp is powered by one included rechargeable 6 Volt, 4 Amp Hour sealed lead acid battery. Recommended recharge period is twelve (12) hours. The rechargeable battery when in good condition will provide about five (5) to eight (8) hours of use. For extended field operations you should consider buying spare batteries to keep some on charge in reserve. The rechargeable batteries can provide about 500 cycles of charging and discharge. An AC powered charger for the battery is built into the base of each lamp, the power charging cord with plug is stored the compartment at the bottom of the lamp and the cover has a slot to allow charging with the cover in place. The power cord for 220 volt models includes a two prong Euro style male plug; the wall outlets vary from country to country so in some 220 volt countries you may need to bring a wall plug adapter. The 220 volt lamp may be charged in the USA when provided with a wall step-down transformer, just as 115 volt models for the USA may be charged overseas with a step-up transformer.

Special Note: the -26P series lamps can operate for greater spans of time when powered by external 12 volt power sources. This can be an AC to 12 volt DC regulated power supply, or greater capacity rechargeable batteries. Be sure to specify whether or not you want Company Seven to include the Adapter Cord (PN 58-0127-02) to operate the lamp from external 12 volt sources.
The molded plastic bodies of this series share the common dimensions of: 5.5 x 3.0W x 9.8H inches (140 x 76 x 249mm). With its rechargeable batteries the lamp weighs 4.3 lbs (1.95 kg).

Options: Rechargeable Power For Field Lamps
Some of our UVP portable and rechargeable lamps operate from a 12 volt DC power, usually an internal battery. In addition to this, the units can be operated in the field from one or more batteries, or from a solar array (practical when operating during the day but on a C-10P cabinet). Company Seven sells portable rechargeable 12 volt battery packs that feature smart engineering, robust metal chassis with LCD Voltmeter to indicating voltage under load and static, and each cigarette lighter style 12 volt outlet (Positive/Hot is the tip) is circuit breaker protected by 5 amp or 10 amp breakers. Each is provided with a sophisticated charger with trickle capability and all this can be carried in the provided fitted durable nylon carrying bag:
For a casual session of observing or prospecting, then we recommend the lighter weight 18 AH Pack. However, for long weekends of observing or for overnight sessions then we recommend either having multiple 18 Amp Hour rated packs, or relying on the larger 33 AH Pack. In time (some years typically) when the rechargeable batteries loose their capacity, then it is a simple matter to replace the battery as these are sold separately by Company Seven and by numerous battery specialty shops. Company Seven does not recommend operating sensitive 12 volt DC equipment from a running motor vehicle since a malfunctioning alternator or voltage regulator (as well as vehicle power demands) can produce power surges and appreciable amounts of AC power which may damage your instrument.
The Chromato-Vue® C-10P Mini UV Cabinet accommodates any one the '-26P' series portable lamps: UVL-26P, UVM-26P, UVSL-26P. Right: the C-10P Mini UV Cabinet accepts any one the '-26P' series portable lamps Longevity 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.

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.
