The Violet300 UVB LED Light is a complete, ready-to-connect professional UV irradiation fixture built around the 281 mm Violet light engine. This version uses 12 UV LEDs at 308 nm and delivers approximately 745 mW radiant power through a 39° optical distribution.
Unlike a bare UV board, Violet300 combines the LED source, secondary optics, thermal housing, integrated control electronics, mounting hardware and connection cable into one coordinated fixture. The approximately 296.5 mm light body is supplied with adjustable brackets and a 3 m silicone cable for direct integration into industrial or laboratory equipment.

Built around LEDiL VIOLET-12X1 optics
The internal 281 mm LED board uses a fixed 12-LED pitch matched to the LEDiL VIOLET-12X1 optics family. Violet300 therefore combines a known LED geometry with a defined secondary optic instead of placing a generic UV source behind an arbitrary lens.
The medium beam balances irradiance and illuminated area, making it a practical choice for general-purpose process irradiation where the fixture is mounted at moderate working distance.
Optical output, beam angle and irradiance simulations are subject to the tolerances specified for the Violet family; simulation-derived values are typically specified with ±20% tolerance where applicable.
Design from irradiance and dose
Radiant power describes the total UV output of the fixture, but the target receives irradiance in W/m² or mW/cm². The resulting irradiance depends on radiant power, optic, working distance, alignment and illuminated area. For dose-controlled processes, exposure time must also be included.
This makes Violet300 particularly useful when the irradiation field must be engineered rather than approximated: the wavelength, optic and fixture position can be selected around a target area and then verified at the actual working distance.
Supplemental UVB for controlled-environment horticulture
The 308 nm UVB version can be used in research and controlled-environment crop systems where a deliberately limited UV component is part of the lighting protocol. See our broader guidance on supplemental horticulture lighting.
UVB exposure must be designed independently from PAR lighting. Irradiance, duration and distance should be validated for the crop and objective because excessive UVB exposure can damage plant tissue.
Wavelength-specific UV curing and photochemical processes
The 308 nm output can be used in UV curing and photochemical processes where the initiator or material is responsive at this wavelength. The selected optic controls whether radiant power is concentrated onto a smaller work area or distributed over a wider process zone.
48 V power, dimming and process control
The integrated electronics accept an electronically regulated DC supply in the 30–50 V range, with 48 V as the nominal reference. At 48 V, input current is below approximately 600 mA and total input power is below 29 W.
The 3-core cable provides +Vin, GND and DIM. The DIM input supports PWM control and remote on/off, allowing the UV source to be synchronized with conveyors, process cycles, shutters or safety logic. If the dimming conductor is not used it should be isolated and left unconnected.
Mechanical integration and thermal management
The hard-anodised aluminium housing acts as the heat sink for the internal Violet LED engine. Adjustable stainless-steel brackets allow the fixture to be aimed without redesigning the host machine, while the sealed optical frame protects the LED/optic assembly.
Maintain free convection around the housing and do not obstruct the optical window or the Tc measurement area. UV radiant output and lifetime are temperature-dependent, so the final installation should be validated at the intended ambient temperature and duty cycle.
Professional UV safety
Violet300 is a Risk Group 3 UV source intended for professional integration. Direct or reflected radiation can injure eyes and skin. The completed machine or luminaire must provide appropriate shielding, interlocks, access control, warning labels and operating procedures for the wavelength and irradiance used.
Installation and wiring should be carried out by qualified personnel. Before operation, verify polarity, DIM wiring, mounting, aiming, shielding and all safety interlocks.
Developed and manufactured in Germany
We develop and manufacture Violet UV modules and integrated irradiation fixtures in Germany. Our capabilities cover UV LED selection, optics, PCB design, thermal engineering, control electronics, mechanical integration, prototyping and series production.
For OEM projects, Violet300 can serve as a starting platform for custom wavelength, optical distribution, control interface and mechanical-integration requirements, subject to technical feasibility.
