Build Your Own High-Intensity UV Solutions
Whether you are a specialized technician at Sun Cheong Computer or a STEM hobbyist, standard UV lights often lack the power needed for fast results. This 10W UV LED Bead is engineered to bridge the gap between consumer toys and industrial equipment.
Optimized for Curing and Inspection
Emitting a focused 395nm wavelength (UV-A), this LED hits the "sweet spot" for interacting with photo-initiators. It is highly effective for curing LOCA glue (used in phone screen repairs), UV-reactive resins, and checking security features on banknotes or ID cards.
Heavy-Duty Performance
Unlike standard 1W or 3W LEDs, this 10W unit features a multi-chip array designed for high-intensity output. The integrated aluminum star PCB acts as a primary thermal transfer interface, making it easier to mount onto a heatsink.
Critical Usage Note:
High power generates high heat. To prevent burnout within seconds, you must use a heatsink with thermal paste or a cooling fan. Do not run this LED on the bare aluminum star base alone.

FAQ Section
FAQ Section
Q: Can I connect this directly to a 5V USB charger?
A: While the range is 3-5V, LEDs are current-driven devices. Connecting directly to 5V without a current-limiting resistor or LED driver may overheat and destroy the chip. We recommend using a constant current driver.
Q: Is this light safe for my eyes?
A: No. This is a high-power UV source. Never look directly at the emitter when active. UV radiation can damage eyes. We recommend wearing UV-blocking safety glasses during operation.
Q: Why does the light flicker or dim after a few seconds?
A: This usually indicates thermal throttling or overheating. Ensure the LED is firmly attached to a sufficient heatsink with thermal paste. The star base alone is not enough to dissipate 10W of heat.
