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 engineering teams building controlled ultraviolet systems. These UVC strip lights combine 275nm and 395nm wavelengths in one SMD3535-based product, reducing the need to install separate linear boards for UVC and UVA functions.
The 275nm band can be evaluated as the primary short-wave ultraviolet source in a completed device. The 395nm band can support fluorescence excitation, process observation, alignment checks, or an auxiliary optical function when compatible materials are used. Final performance depends on the complete optical, electrical, mechanical, and control design.
24 LEDs per Meter
Each meter contains 24 SMD3535 LEDs. The wider spacing between LED positions distinguishes this model from higher-density strip designs and helps equipment developers select an arrangement that matches the required installation length, component count, power budget, and target coverage.
The UVC strip lights emit through a specified 120-degree angle. Coverage at the working surface will depend on the distance from the strip, the arrangement of multiple sections, enclosure reflections, target shape, and any window or protective cover placed between the LEDs and the treatment area.
Electrical Characteristics
These UVC strip lights are offered in 12V and 24V versions, with a working power of 5W per meter. The selected voltage must be confirmed before production and connected only to a compatible power supply.
For a five-meter installation, the total electrical load should be calculated from the actual powered length. Equipment designers should also assess voltage drop, cable size, connector capacity, power-entry position, control-device rating, and suitable power-supply headroom.
Physical Construction
The complete strip size is 5000 × 10 × 4mm. Its narrow board supports installation in compatible linear channels and compact internal structures. The UVC strip lights may be routed along straight or gently curved equipment surfaces when the mechanical design permits.
The supplied specification does not define a cutting interval, minimum bending radius, adhesive backing, or maximum single-end feed length. These details should be confirmed before finalizing the housing, cutting plan, solder-pad position, or production wiring.
Spectral Characteristics
The specified wavelengths are 275nm and 395nm, and the spectrum FWHM is 10nm. Because UVC and UVA have different optical behavior, each band should be measured with equipment that is suitable for its wavelength range.
A material that transmits 395nm radiation may not provide equivalent transmission at 275nm. Any window, sleeve, coating, encapsulant, adhesive, or protective cover used with the UVC strip lights should therefore be evaluated at both specified wavelengths.
4oz Copper PCB
The UVC strip lights use a 4oz copper PCB. The thicker copper layer supports current distribution and heat spreading across the five-meter board, but it does not replace application-specific thermal design.
Operating temperature should be checked after the UVC strip lights are mounted inside the intended enclosure. Installed length, duty cycle, airflow, ambient temperature, mounting surface, and enclosure volume can all influence PCB and LED temperatures.
IP20 or Customized Waterproofing
The standard UVC strip lights have an IP20 rating for protected equipment integration. Waterproof construction can be customized when the project requires additional environmental protection.
The selected waterproof material should be assessed for sealing reliability, heat retention, UV transmission, and long-term exposure to both 275nm and 395nm radiation. Connection points and cable entries should be included in the environmental-protection design.
Custom Connection Options
The UVC strip lights use a customizable connection method. Project requirements may include a particular connector, wire length, cable gauge, polarity mark, power-entry direction, or preassembled lead arrangement.
Providing a mechanical drawing, voltage selection, installed length, operating cycle, mounting method, and target quantity can help define the correct UVC strip lights configuration before sampling or volume production.

Product Applications
Enclosed Air-Handling Equipment
The UVC strip lights can be evaluated for controlled air channels, recirculation equipment, filtration housings, and enclosed ventilation components. Strip placement can be adapted to the internal geometry of the equipment.
Surface-Treatment Chambers
Linear sections can be installed inside closed cabinets, boxes, conveyors, or process chambers to distribute ultraviolet output along selected surfaces. Multiple mounting positions may be used when the equipment contains corners or areas subject to shadowing.
Fluorescence and Process Inspection
The 395nm UVA component can be tested with compatible fluorescent coatings, markers, inks, minerals, adhesives, or inspection materials. It may also provide an auxiliary optical reference during an automated process.
Sealed Water-Treatment Assemblies
The product can be considered as a component in a sealed water-treatment structure when it is isolated from water by an appropriate UV-transmitting barrier and protected electrical assembly. The standard IP20 version is not intended for direct immersion.
Laboratory and OEM Systems
These UVC strip lights offer a dual-band linear platform for prototypes, analytical fixtures, experimental chambers, customized machines, and other equipment requiring 275nm and 395nm sources on one board.
