Customization options include wavelength, wattage, lamp length, LED array, lamp base, glass structure, electrical design, logo and package.
What Is a UVA Light Bulb?
A UVA light bulb is a type of ultraviolet lamp designed to emit light in the UVA wavelength range.
Common UVA wavelengths used in LED and blacklight products are 365nm and 395nm.
Compared to normal visible-light bulbs, the selection of a UVA bulb is done by its ultraviolet wavelength and optical performance, not by visible brightness.
The common applications are:
Insect traps
Mosquito lamps
Bug zappers
Fluorescence inspection
Blacklight equipment
Security inspection
UV-reactive displays
Industrial inspection
Specialized OEM equipment
A UVA bulb is a different product from UVC germicidal lamp and should not be referred as a normal sterilization light source.
365nm UVA Light Bulbs
The 365nm UVA light bulb has a long-wave ultraviolet emission with relatively low visible violet light interference.
So, the 365nm is used where the UV reaction is more important than visible purple glow.
Common applications are:
Insect light traps
Fluorescence inspection
Anti-counterfeit checking
Security markings
UV-reactive materials
Industrial inspection
Blacklight equipment
In the case of fluorescence application, 365nm wavelength can produce a darker visual background compared to a shorter one near visible violet wavelength.
The real response depends on the target material, lamp output, distance and surrounding lighting.
365nm + 395nm UVA LED Bulbs
We produce 365nm+395nm dual-wavelength UVA LED bulbs.
The 365nm has a main long-wave ultraviolet output while 395nm provides the ultraviolet output near the visible violet light.
The dual-wavelength bulb can be used in:
Mosquito lamps
Insect traps
Bug zapper equipment
Blacklight systems
UV-reactive displays
Custom UV equipment
Dual-wavelength lamp is not always a powerful light source than single wavelength. The choice of wavelength depends on the application and overall equipment design.
For insect-attracting projects, we recommend to test the finished insect trap using the target insects under actual installation conditions before mass production.
365nm vs 395nm UVA Light
365nm and 395nm are two of commonly used UVA wavelengths that don’t look and perform the same way.
365nm has less visible violet output and is chosen where the fluorescence contrast is more important.
395nm is close to visible violet, the lamp appears brighter or more purple.
A brighter purple light bulb does not mean the lamp emits more UVA.
For professional applications, choose the lamp wavelength according to the target material or equipment needs not according to the visible brightness alone.
UVA LED Bulbs for Insect Traps
UVA light sources are widely used in equipment that attracts flying insects.
Our UVA LED lamps can be used in:
Mosquito traps
Fly traps
Glue-board insect traps
Electric bug zappers
Commercial pest control equipment
Food service insect control equipment
Custom flying insect management products
365nm and dual 365nm+395nm are available depending on the lamp design.
However, the lamp is just a part of an insect trap. Final attraction performance can depend on:
Wavelength
UVA output
Lamp position
Optical distribution
Trap geometry
Installation height
Ambient lighting
Airflow
Target insect species
For OEM projects, it is better to test the finished insect trap rather than choosing the lamp by wattage alone.
T8 G13 UVA LED Tubes
We have T8 UVA LED bulbs for compatible G13 fixtures and insect-control equipment.
Depending on the model, various lamp lengths and power ratings are available.
The UVA LED tubes can be used for:
Insect trap replacement
Bug zapper equipment
Mosquito lamps
Blacklight fixtures
UV reactive inspection equipment
Before changing an existing fluorescent UVA lamp to LED one, check:
G13 socket
Tube length
Input voltage
Ballast type
Wiring method
Single or double end power structure
Fixture dimensions
T8 tube and G13 socket do not guarantee the electrical compatibility with every fluorescent fixture.
E27 UVA LED Bulbs
For equipment that has a screw-in lamp, we have E27 UVA LED bulbs.
These compact lamps are suitable for compatible:
Hanging insect traps
Bug zapper fixtures
Mosquito lamps
Blacklight equipment
Custom OEM devices
E27 design allows easy lamp replacement in equipment that is based on screw structure.
However, voltage, dimensions and electrical design should be still compatible with the fixture.
If U.S. project requires an E26 socket instead of E27, mention it in OEM design stage.
UVA LED vs Fluorescent UVA Lamps
Fluorescent UVA lamps are widely used in insect traps and industrial blacklight equipment.
LED technology is another option for UVA lamps.
LED UVA lamps have advantages such as:
Instant startup
Compact electronic design
Low voltage LED design inside appropriate equipment
Long service life
Various wavelength combinations
Reduced maintenance
Mercury free LED light source design
The traditional fluorescent UVA lamps can be more appropriate for equipment designed with fluorescent tubes and ballasts.
Electrical Wattage vs UVA Output
Electrical wattage and UVA optical output are two different parameters.
For example, 10 watts lamp uses the electrical power according to its rated design.
But it does not mean that this lamp has 10 watts of UVA output.
The useful parameters for the professional evaluation of UVA lamp are:
Electrical power
Peak wavelength
UVA radiant output
Irradiance
Measurement distance
Beam or emission angle
Operating temperature
Two lamps with the same electrical wattage can emit different amount of UV light depending on LED, driver, thermal design and optical structure.
For OEM projects, measured UVA output is more important than wattage.
Lamp Base and Size Compatibility
Replacement UVA light bulb should be chosen by more parameters than wavelength.
The important parameters are:
Lamp base
Tube or bulb type
Overall lamp length
Lamp diameter
Input voltage
Wiring method
Fixture design
Available installation space
For example, E27 bulb cannot replace G13 T8 tube even though both lamps have 365nm UVA wavelength.
Also, two different G13 T8 tubes may have different lengths and won’t fit the same equipment.
Check all parameters of the replacement lamp.
Transparent, Frosted and Coated UV Bulbs
Various UVA lamp designs use different types of transparent, frosted or coated outer structures.
These changes can change the appearance of the lamp and can influence the optical transmission and visible light properties.
The best type of the lamp structure depends on the application.
For the professional UV equipment, the final lamp structure should be evaluated for:
UVA transmission
Visible light transmission
Optical uniformity
Temperature
Mechanical strength
Performance in application
When the UVA output is important, measured spectral and radiant data is more important than lamp appearance.
Lifetime and Thermal Management
The lifetime of the LED depends not only on LED chip itself.
Operating temperature, drive current, driver quality and thermal design influence the lamp lifetime.
The UVA LED bulb made for continuous operation in an insect trap should be tested under realistic operating conditions.
Important parameters are:
Ambient temperature
Enclosed fixture temperature
Operating hours
Driver temperature
LED junction temperature
Ventilation
For OEM project, the lamp and fixture should be evaluated as a thermal system.
How to Choose a UVA Light Bulb
Before ordering a UVA bulb, check the following points:
Required wavelength
Target application
Lamp type
E26, E27, G13 or other base
Required lamp length
Input voltage
Electrical power
Required UVA output
Continuous or intermittent operation
Fixture and ballast design
Glass or coating requirement
Installation environment
If the lamp will be used in an insect trap, also let us know the equipment size, lamp position and target application.
Our engineers can help to choose the best starting configuration.
UVA Light Bulb Safety
The UVA is ultraviolet radiation and should not be treated like an ordinary visible lighting.
Do not expose your eyes and skin to the UV unnecessarily.
In case of high intensity, short range or professional UV application, you should consider protection.
The equipment manufacturer should evaluate the optical safety depending on the lamp output, exposure distance, duration and application.
The UVA lamps should be clearly distinguished from the UVC germicidal lamps in order to show users the purpose of the product.
