Specific Safety Considerations
Dymax ECE flood lamps are designed to maximize operator safety and minimize exposure to UV light-
curing energy. To use the unit safely, it must be set up and operated in accordance with the instructions in
this user guide. Please also read and understand the safety considerations unique to UV light-curing
systems as described below.
WARNING! Looking directly at the UV light emitted by an ECE flood lamp can result in eye
injury. To prevent eye injury, never look directly at the high-intensity light and always wear
protective goggles (provided).
Dymax UV Light-Curing System Safety Considerations
Operators must understand these four concepts to use the UV light source safely:
■UV exposure
■High-temperature surfaces
■Ozone
■Bright, visible light
Each is described below.
UV Exposure
Standard Dymax UV light-curing systems and bulbs have been designed primarily to emit UVA light (Figure 1).
UVA light is generally considered the safest of the three UV ranges: UVA, UVB, and UVC. Although OSHA
does not currently regulate ultraviolet light exposure in the workplace, the American Conference of
Governmental Industrial Hygienists (ACGIH) does recommend Threshold Limit Values (TLVs) for ultraviolet
light.
The strictest interpretation of the TLV (over the UVA range) for workers’ eyes and skin is 1 mW/cm2
(intensity), continuous exposure. Unless workers are placing bare hands into the curing area, it is unusual

6
Dymax ECE Series UV Flood Lamps User Guide
to exceed these limits. To put 1 mW/cm2limit into perspective, cloudless summer days in Connecticut
regularly exceed 3 mW/cm2of UVA light and also include the more dangerous UVB light (primarily
responsible for sun tans, sun burns, and skin cancer) as well.
Figure 1. UV Spectrum
Checking the Workstation
The human eye cannot detect “pure” UV light, only visible light. A radiometer should be used to measure
stray UV light to confirm the safety of a UV light-curing process. A workstation that exposes an operator to
more than 1 mW/cm2of UVA continuously should be redesigned.
Protecting Operators
Light-curing technology can be a regulatory compliant, “worker-friendly”manufacturing process when the
proper safety equipment and operator training is utilized. There are two ways to protect operators from
UV exposure: shield the operator and/or shield the source.
Shield the Operator —UV-Blocking Eye Protection - UV-blocking eye protection is recommended when
operating UV light-curing systems. Both clear and tinted UV-blocking eye protection is available from
Dymax.
UV-Blocking Skin Protection —Where the potential exists for UV exposure upon skin, opaque, UV-
blocking clothing, gloves, and full-face shields are recommended.
Shield the Source of UV
Any substrate that blocks UV light can be used as a shield to protect workers from stray UV light. The
following materials can be used to create simple shielding structures:
Rigid Plastic Film —Transparent or translucent/UV-blocking plastics (typically polycarbonate or acrylic)
are commonly used to create shielding where some level of transparency is also desired.
Flexible Film —Translucent UV-blocking, flexible urethane films can be used to quickly create
workstation shielding. This UV-blocking, flexible urethane film is available from Dymax, call for assistance.
Ozone
Standard Dymax bulbs (UVA type) generate an insignificant amount of UVC and therefore essentially no
ozone. Some UV light-curing systems, like those used to cure UV inks, emit primarily “shortwave” (UVB

Dymax ECE Series UV Flood Lamp User Guide
and UVC) energy. Upon exposure to UVC light (specifically <240 nm), oxygen molecules (O2) split into
oxygen atoms (O) and recombine with O2to create ozone O3. The current, long-term ozone concentration
limit recommended by ACGIH, NIOSH, and OSHA is 0.1 ppm (0.2mg/m3).
High-Temperature Surfaces
Surfaces exposed to high-intensity curing lights will rise in temperature. The intensity, distance, exposure
time, cooling fans, and the type/color of the surface can all affect the actual surface temperature. In some
cases, exposed surfaces can reach temperatures capable of producing a burn or causing damage to a
substrate. In these cases, care must be taken to ensure either a more moderate surface temperature or
appropriate protection/training for operators.
Bright, Visible Light
The bright, visible light emitted by some UV light-curing systems can be objectionable to some workers
and can cause eyestrain. Tinted eye protection and/or opaque/tinted shielding can be utilized to address
this concern.
Summary
UV-light sources can be more “worker friendly” than many commonly accepted industrial processes,
provided the potential concerns are addressed. Both the lower working temperature and lack of spurious
frequency transmission that this system produces make it even more user friendly. Contact your Dymax
representative for information regarding the proper use of Dymax light-curing systems.
Product Overview
Description of the ECE Series Flood Lamps
Dymax ECE series UV light-curing flood lamps are general-purpose units for the curing of UV light-curable
adhesives, coatings, and inks. They have extensive use in a wide variety of applications such as bonding,
potting, sealing, and encapsulating. These light sources are extremely unique in that they offer exceptional
versatility and expandability.
The design of these units has been carefully considered to allow the light source to be successfully utilized
in a wide variety of manufacturing situations.
Each system is designed and shipped in a unitized configuration for easy bench-top mounting with all
controls and functions right at the hands of the operator. Each system can also be custom configured for
mounting of the lamp/reflector assembly housing in a remote curing location and the power supply can be
mounted several feet away within the easy reach of an operator. The lamp/reflector assembly housings
have been designed with clean, unobstructed surfaces for maximum ease of installation in existing or
specialized equipment.
Several lamp/reflector assembly housings can be mounted side-by-side in a linear configuration or a large
area array. The power supplies can then be stacked and mounted remotely to provide consolidated
operator control.
