Germicidal Lamps are low pressure mercury vapor lamps which produce ultraviolet rays that are lethal to micro organisms. Radiations are generated by an electrical discharge through low pressure inert gases and mercury vapor within the special quartz tube of the lamp. Approximately 95% of the UV rays from the lamp are at the wave length of 2537A,(commonly referred to as 254nm) which is the region of maximum bactericidal effectiveness. First Light Technologies, Inc.’s Germicidal lamps are available in "L" Quartz (non-ozone) and "VH" Quartz (very high ozone).

Applications - Germicidal lamps are utilized in many applications including:

•Residential, Commercial and Industrial
•Water Purification
•Wastewater Treatment
•Aquacultural Water Treatment
•Air Purification
•Food conveyor purification
•Ink Curing Applications

Ozone     Besides producing 2537 Angstrom unit wave lengths of ultraviolet, some germicidal lamps are designed to produce controlled amounts of a shorter wave length of ultraviolet measured at 1850 Angstrom units (commonly referred to as 185nm). This wave length has the power of generating ozone which is a form of oxygen and is an extremely effective germicidal agent. Ozone also has the power of oxidizing odor molecules and therefore acts as a deodorizer. A further advantage is that ozone can be carried by air into places that the UV rays cannot reach directly.

Ozone producing lamps are commonly used for pool and spa water treatment, T.O.C. reduction and air purification.

Hot Cathode Lamps    Hot Cathode Lamps have triple-coiled filaments as cathodes that are heated by the arc current. First Light Technologies utilizes a filament construction with a nickel inner lead in a clamped filament design similar in construction to a standard fluorescent lamp.

Slimline or instant start lamps utilize high voltage for starting and are especially suited to applications such as water purification. Preheat lamps use a glow switch starter to preheat the filament prior to starting and generally use standard fluorescent ballast which provide the advantages of space and economy.

Custom Germicidal Lamps      First Light Technologies, Inc. offers the capability of manufacturing a wide variety of ultraviolet lamps designed to your specifications and application.  A wide range of glass types, glass diameter, cathodes, bases, shapes and lengths can be utilized to produce a lamp to meet your unique requirements.    In-house engineering capability and manufacturing capacity allow First Light to significantly reduce the lead-time from concept to production.   First Light welcomes the opportunity to provide engineering support in response to your specific application.

Amalgam Lamps - First Light Technologies, Inc. offers amalgam lamps that deliver up to 3 times the UVC output of standard low pressure UVC lamps. First Light Technologies’ Amalgam series of lamps are designed to operate efficiently at higher operating temperatures than standard and (HO) lamps. These benefits allow equipment manufacture to realize greater efficiency and lower equipment cost. First Light’s amalgam series is a cost effective alternative to medium pressure lamps. In house manufacturing capabilities allow First Light to provide the OEM with a lamp that fits their equipment needs. Key Features include:

• Increased UV dosage without increasing size
• Greater efficiency; fewer lamps = lower equipment costs
• Greater stability of UVC output over varying temperatures

HO Lamps - First Light Technologies, Inc. offers High Output (HO) in all lamp configurations; these lamps will deliver up to two thirds more UV output than standard lamps.  First Light’s HO lamps are offered with the standard HO filament or can be equipped with our long life electrode.

First Light’s long life filament is a single piece construction, High Output filament. This filament type provides added benefits over conventional filament types. This filament can be operated from 600 to 1200mA. Single piece construction offers greater durability and helps reduce the occurrence premature burnout. The use of this filament offers greater UV output than those using conventional filaments.

First Light Technologies, Inc. works closely with the OEM to customize a high output lamp solution that is configured to meet the OEM’s specific application. Engineering support includes proper ballast selection and sourcing.

Internal Coated Lamps -

Lower equipment costs by reduced lamp quantities (Higher dosage at end of life)

Quartz Sleeve Fabrication - First Light’s germicidal lamps and quartz sleeves are manufactured using 99.9% pure fused quartz. This material allows for maximum UV transmission. Quartz sleeves are available in a wide variety of lengths and diameters. First Light’s capabilities include cutting, doming, bending, polishing, splicing, and flaring. Other operations are available upon request.

Custom Ceramic Onlay - First Light Technologies, Inc. can provide lamp bases customized with your logo, product number, country of origin and/or reorder information. The single or multi color onlay is bonded to the ceramic base with an intense heat process that fuses the pigment to the ceramic base. This process provides durable and clear labeling making an exceptional quality product presentation.

Bases    First Light Technologies, Inc. offers a complete selection of standard plastic and ceramic bases to meet your specifications. In addition to standard bases, First Light specializes in creating custom base designs supporting your proprietary equipment. In-house capability and capacity allow First Light to significantly reduce the lead-time from concept to production.
