Industrial-grade 20W UV LED emitter with a 380-385nm peak. Engineered for high-speed resin curing and high-intensity fluorescence.
The 20W SMD High Power LED (380-385nm Purple) is an industrial-grade powerhouse designed to deliver concentrated UVA energy at a precise 380nm peak. This is not a mere indicator light; it is a high-intensity engine engineered for rapid polymer cross-linking, ultra-fast resin curing, and professional-grade scientific applications where every milliwatt of radiant flux matters.
The Probots quality advantage is critical when managing 20 Watts of concentrated energy, where thermal stability determines the life of your component. Our emitters are Probots™ ProSpec Grade , featuring a high-purity red copper substrate for the fastest possible heat transfer to your cooling system. To guarantee you receive the exact spectral output required for your specialized projects, every batch is Probots™ Lab Verified in our Bangalore facility to confirm the 380-385nm peak using calibrated spectrometers. Furthermore, we ensure your investment arrives in perfect condition with Probots™ Secure-Transit shock-resistant packaging, protecting the delicate COB surface from physical damage during shipping.
Beyond simple curing, this 20W chip is a versatile asset for specialized fields ranging from high-security document authentication to material stress testing and advanced horticulture. It is particularly effective for Industrial UV Curing, where it can trigger near-instant hardening of UV-sensitive glues that lower-power 3W or 10W LEDs struggle to penetrate. If you have found standard UV modules insufficient for deep resin casts or daylight-visible fluorescence, this Probots™ LifeCycle Ready 20W variant provides the professional-grade upgrade your workstation or production line demands.
Safe and efficient operation requires professional technical management due to the extreme radiant intensity. This high-power COB generates massive heat and MUST be mounted on a large aluminum heat sink with an active cooling fan to prevent immediate thermal destruction. Because this is a Probots™ Logic-Safe component, we strictly recommend driving it with a dedicated constant current LED driver (600mA-700mA) in the 30-34V range. Always prioritize safety by wearing UV-rated goggles and avoiding all direct skin exposure while harnessing the high-intensity capabilities of the deep UVA spectrum.
