275nm + 395nm UVC Strip Lights, 24 LEDs/m
Product Details
Dual-Band UV Source for Equipment Development
The yoyouv LS-3535-24D-12V-UVC+UVA is designed for manufacturers, laboratories, and engineers who develop their ultraviolet systems. These UVC strip lights combine 275nm and 395nm wavelengths within one SMD3535-based module; thus, there is no need to install separate linear boards with UVC and UVA options.
The 275nm band can be classified as a short-wave ultraviolet light source in the developed device. The 395nm band can be used to excite fluorescence, monitor processes, make alignments, or perform any auxiliary optical task in compatible materials. The ultimate performance will depend on the entire optical, electrical, mechanical, and control design.
24 LEDs per Meter
There are 24 SMD3535 LEDs in one meter. The bigger distance between LED positions makes this model unique compared with other high-density strips, and equipment developers have the opportunity to select the appropriate installation configuration according to the necessary installation length, component count, power consumption, and coverage area.
Emission angles of UVC strip lights are declared to be equal to 120 degrees. The coverage on the work surface will depend on the distance from the strip, several strips configuration, reflections from the enclosure, target geometry, and window or cover between the LEDs and the treatment area.
Electrical Characteristics
These UVC strip lights can be manufactured in 12V or 24V; the working power is 5W per meter. The necessary voltage must be checked before the manufacturing and connecting to the corresponding power supply.
For the calculation of the electrical load for the five-meter installation, the exact length of powered part should be considered. The equipment developer needs to evaluate voltage drop, diameter of the cable, connector’s capacity, point of power input, control device rating, and adequate power supply headroom.
Physical Construction
The total strip dimensions are 5000 × 10 × 4mm. The narrow strip makes it possible to install the UVC strip lights in compatible linear channels and compact enclosures. The UVC strip lights can be installed along the straight or slightly curved equipment surfaces provided by the mechanical design.
The current specification does not contain the information about the cutting interval, minimum bending radius, adhesive backing, and maximum single-end feed length. These parameters must be confirmed before the finalization of the housing design, cutting pattern, location of solder pads, or wiring manufacturing.
Spectral Characteristics
The wavelengths of the two specified bands are 275nm and 395nm. The spectral width (FWHM) is 10nm. Since UVC and UVA have different optical characteristics, the measurement of each band must be performed with the corresponding equipment.
Materials that transmit the 395nm radiation cannot guarantee the same level of transmission for 275nm. Therefore, any window, sleeve, coating, encapsulant, adhesive, and protective cover used with the UVC strip lights should be measured in two wavelengths.
4oz Copper PCB
The UVC strip lights use 4oz copper PCB. The increased thickness of the copper layer allows the current distribution and heat spreading along the entire five-meter strip; however, it does not replace the application-specific thermal design.
Operating temperature should be evaluated after the mounting of the UVC strip lights in the intended enclosure. The installed length, duty cycle, airflow, ambient temperature, mounting surface, and enclosure volume can affect the temperature of the PCB and LEDs.
IP20 or Customized Waterproofing
The standard IP20 protection class enables integration of these UVC strip lights into the protected equipment. The waterproof version can be customized according to the project requirements.
The selected waterproof material must be tested for sealing efficiency, heat accumulation, UV transmission, and durability under 275nm and 395nm radiation. Connection points and cable feed-through must be considered in the environmental protection design as well.
Custom Connection Options
The UVC strip lights offer the custom connection method. Project requirements can include a specific connector, wire length, cable diameter, polarity marking, orientation of power input, or pre-assembled lead assembly.
The provision of the mechanical drawing, voltage choice, installed length, operating cycle, mounting method, and target quantity can help to clarify the configuration of the required UVC strip lights before sampling or bulk production.

Product Applications
Enclosed Air Handling Equipment
UVC strip lights can be reviewed for controlled air channels, recirculation systems, filtration chambers, and enclosed ventilation components. The strip lighting can be placed according to the inner structure of the equipment.
Surface Treatment Chambers
Linear modules can be placed into closed cabinets, boxes, conveyors, or process chambers to emit ultraviolet output across selected surfaces. Various installation points can be applied if the equipment features corners or zones prone to shadowing.
Fluorescence and Process Inspection
The 395nm UVA light source can be tested with compatible fluorescent paints, markers, inks, minerals, adhesives, or inspection materials. It can serve as an additional optical reference in an automated process.
Sealed Water Treatment Assemblies
This product can be considered for inclusion into a sealed water treatment system if the light is isolated from water with a UV-transparent barrier and appropriate electrical assembly. Standard IP20-rated device is not intended for submersion.
Laboratory and OEM Systems
This dual band linear strip lights can be useful for prototypes, analytical fixtures, experimental chambers, customized machines, and other equipment that requires two ultraviolet wavelengths (275nm and 395nm) at once on one board.
