DATASHEET
The HPG400WER is a battery-powered, handheld, UV lamp that delivers high-intensity 1 W/cm² irradiation at a 2-inch distance over a 3 mm × 3 mm area using a 40 W UV LED. It has a UV bandpass filter with visible light cutoff optical black glass. It is the most powerful battery-powered handheld UV lamp on the market. The UVFL features a specially designed UV collimating lens that maximizes intensity and homogeneity. With an internal cooling fan, it has a long operation time of up to 6 hours on its high-capacity 18 AH 25 V rechargeable battery. The battery is exchangeable so that one can purchase two batteries to continue the work while another battery is charging. The design leverages multi-year military UV gear developments, resulting in a ruggedized manufacturing tool for the mass market. The HPG400WER UV lamp is ideal for fast and deep epoxy curing, with continuous operation on a single battery charge, homogeneous illumination, lightweight construction, and ease of use. The lamp can be switched on and off with a finger-press button switch. An optional pluggable power supply and controller allow for hands-free operation with a foot switch pedal. The controller features a timer with settings from 0.01 to 10 hours, and the illumination power is adjustable from 10% to 99%. We offer three wavelengths — 365 nm, 405 nm, and 440 nm — optimized for specific UV epoxy and paint curing applications. Additionally, we produce optical power meters that fit the head size to accurately measure and calibrate the power level.

Advanced Features
Optical Lens System For Maximum Intensity and Homogeneity
The special LED and lens system deliver high UV light intensity that burns paper (no competitor can achieve). The optics also enable homogeneity over the entire irradiation area as illustrated above.
Cooled LED For Constant Light Intensity and Long Lifetime
For constant light intensity and long lifetime, high power LED modules require temperature cooling. With integrated fan and special heat sinks, our spotlight can operate continuously for a day without intensity change.

Red: Special order that is more expensive due to the lack of volume.
General Safety Statement
UV light is harmful to the eye and skin. Since sunlight contains UV, the effect is well studied. Do not look at the UV light directly. For the spotlight, the power density is concentrated at the focus spot, which quickly reduces at the position away from the focus point.
Questions and Answers
Q: What is the best wavelength I should choose if my epoxies have a wide range of curing wavelengths?
A: All epoxies can be cured at a shorter wavelength since these UV lights are more energetic and provide better and deeper curing. However, not all epoxies can be cured at a longer wavelength that requires a special formulation to be cured thoroughly.
Q: If I want to cure a UV epoxy through a piece of transparent plastic, what wavelength head should I choose?
A: Transparent plastic blocks 365 nm UV light. Therefore one needs to choose an epoxy that can be cured at 450 nm and choose the matching head.
Q: Is the UV head output power calibrated?
A: The output power of each UV head is tested to meet the range stated on the datasheet. Since the output power of each UV head is highly sensitive to the actual sample position, we recommend customers calibrate the power density using a power meter in place of the sample. The power can be changed by adjusting the UV head position using our holder or by setting it in the four-head control box.
Application Notes
Fiber Core Alignment
Note that the minimum attenuation for these devices depends on excellent core-to-core alignment when the connectors are mated. This is crucial for shorter wavelengths with smaller fiber core diameters that can increase the loss of many decibels above the specification if they are not perfectly aligned. Different vendors’ connectors may not mate well with each other, especially for angled APC.
Fiber Cleanliness
Fibers with smaller core diameters (<5 μm) must be kept extremely clean; contamination at fiber-fiber interfaces, combined with the high optical power density, can lead to significant optical damage. This type of damage usually requires re-polishing or replacement of the connector.
Maximum Optical Input Power
Due to their small fiber core diameters for short wavelengths and high photon energies, the damage thresholds for the device are substantially reduced compared to the common 1550 nm fiber. To avoid damage to the exposed fiber end faces and internal components, the optical input power should never exceed 20 mW for wavelengths shorter than 650 nm. We produce a special version to increase the power handling by expanding the core size at the fiber ends.
