The capillary lamps are a fragile product. Handling and operation must be clearly understood. Most conditions associated with lamp return are a direct result of incorrect operation and or mishandling. 1. Capillaries are a Graded Seal Lamp, making this product impossible to hear in an annealing process. The quartz at the graded ends of the lamp has a lower melting point than the quartz body. The annealing process heats the lamps in a furnace for a given period of time. This process relieves the stress during the lamps manufacturing process. The lack of annealing results in a lamp that is very fragile requiring great care in installation. 2. The ON and OFF cycling of the lamp is temperature related. Capillary lamps are designed for intermittent operation only. The longer or hotter the burn period the shorter the lamp life. Typical life rating is 7000 shots at 40 seconds or less, 3000 shots for over 40 seconds. If the ON cycle is extended, the lamps internal pressure increases, as well as the potential for violent lap failure. It the OFF time is too short, the rise time into the mercury vaporization may be effected and the migration of the mercury away from the electrode to the center of the lamp will be inevitable. This will result in lamp instability and dark electrodes, resulting in early failure and possible lamp explosion. 3. It is critical for proper ignition to manually distribute the mercury into even pools at each end of the lamps in front of the electrodes (see instructions included with each lamp). If the mercury is not properly distributed, the operation ONOFF time may be affected, resulting in a hard-starting lamp which could fail or explode causing short life. As this lamp had a graded seal, there is a large dead spaced behind the electrode tip. This space must be filled to allow a certain portion of mercury to enter into ionization. If all the mercury does ionize, the lamp becomes saturated. Mercury Saturation resulting from an unbalanced lamp will cause unstable current regulation. IT IS VERY IMPORTANT TO BALANCE THE MERCURY! 4. Capillary lamps rated over 1KW require water-cooling. The user must evaluate the rated GPH for the required wattage. Water must be deionized and checked and changed frequently to eliminate ion concentration. Mechanical equipment must be checked frequently for water leaks and gasket failure. 5. Many lamps are returned for breakage during installation. As the lamps end is nickel-plated and the spring load in the system is the same, the lamp must be carefully installed to eliminate the lamps from slopping to one side from the two polished surfaces. This will result in a lamp slightly cocked to one side in the water jacket. This creates a thermal stress when the lamp is heated resulting in hairline cracks in the lamp body and early failure.

Single and double-ended quartz halogen lamps used in RTP (Rapid Thermal Process) or CVD (Chemical Vapor Deposit) applications. Quartz infrared lamps efficiently convert electrical energy into radiated heat. Semiconductor processing equipment manufactured by OEMs such as Applied Materials utilize heat sources to irradiate wafer surfaces. Halogen quartz lamps designed into systems for heat applications allow for high heat transfer operations to be performed in short duty cycles. Quartz halogen filament lamps also allow flexibility for temperature variability as needed for the process because power can be varied. Xenon Arc lamps are used in Semiconductor equipment for Wafer Surface Inspection, Wafer Edge Exposure, Photo Etching, Photo Resist, Stepper Equipment, Liquid Crystal Photolithography, and Mask Alignment.

We carry FAA certified Xenon Searchlight replacement lamps for the SX5 Starburst OEM PN 030060-1 (ULSI PN: ULXS500R244) and SX16 Nightsun OEM PN 017498 (ULSI PN: ULXS1600G244). Universal Light Source works with Law enforcement and Helicopter Parts Distributors, and offers competitive prices and warranties.

Fluorescent lamps are used for UV curing in a number of applications. In particular, these are used where the excessive heat of mercury vapor is undesirable, or where finer grained control over the process is desired. Fluorescent lamps can be created that produce ultraviolet anywhere within the UVAUVB spectrum. Additionally, lamps that have multiple peaks are possible, allowing a wider variety of photoinitiators to be used.

A flashlamp, or flashtube, is an electric arc lamp designed to produce extremely intense, incoherent, full-spectrum white light for very short durations. We supply flashlamps mainly to the digital media industry for curing coatings and bonds. Because Xenon produces a spectrum close to that of daylight, flashtubes are also used in solar simulation. Flashlamps generate bright, attention-getting flashes with a relatively small, continuous input of electrical power, they are also used in aircraft warning lights, emergency vehicle lighting, fire alarm annunciator devices (horn lights), aircraft anti-collision beacons, and other similar applications. Pulsed light (PL) is a technique to decontaminate surfaces by killing microorganisms using pulses of an intense broad spectrum, rich in UV-C light. UV-C is the portion of the electromagnetic spectrum corresponding to the band between 200 and 280 nm. Pulsed light works with xenon lamps that can produce flashes several times per second.

UVA is in the 315 - 420nm wavelength range. This includes Photopolymer (365 - 400nm) and Diazo (400 - 420nm). We carry a wide range of UVA lamps used in curing of inks and lamanants, including medium pressure, metal halide and specialized flourescents. We also supply quartz plates & aluminum reflectors for printing equipment, and digital radiometers.For decades web presses have been used to manufacture and print labels for a wide array of applications. Every type of packaging requires labels for branding, instructions, nutritional facts and more. Labels for Food & Beverage, Medical, Cosmetics & Healthcare, Household products and Private Branding are manufactured using many techniques. UV inks are applied one layer at a time and cured with UV lamps. Universal Light Source, Inc. has been supplying UV lamps for the Label Printing industry for over 35 years. During this time we have acquired a complete understanding of the physic, chemistry and mathematics used in the manufacturing process. We have an extensive list of lamps and a cross reference database for UV lamps used in virtually all presses.

Compact UVC lamps are widely used in HVAC to kill mold spores and bacteria in heating and AC vents, easing symptoms of asthma and allergies. Compact UVA and UVB lamps have various applications in gemology, nail curing, insect trapping, and dermatology.

Deuterium lamps create an arc between the anode and tungston filament that excites molecular deuterium. Light is emmitted as it transitions back to it's initial state. The intense continuum from the vacuum ultraviolet to 500 nm, and the low visible and infrared output, ensure superior signal to noise for many UV measurements. We stock a number of different models from Heraeus, Hamamatsu and others, including part numbers: L1789, DO801, DO302, DO902, D1050, R.23, G.03, 3UNXGa, 5QNCu-Zn, Cu, Pb, As and Hollow Cathode.
