Import 308nm 310nm High Power 1w 3w 3535 Smd Led — Buy in wholesale FOB from Supplier in China

The Greenergy Lighting GL3078-3535H is a surface-mount device (SMD) UV LED in a 3535 package format, available in peak wavelengths of 308 nm, 310 nm, or 311 nm. At a forward current of 100 mA DC, it delivers an optical power output of 12 mW with a forward voltage range of 5 to 8 V. The device emits within a spectrum half-width of 10 nm and a 120-degree viewing angle. Absolute maximum ratings include a continuous forward current of 100 mA and power consumption of 1000 mW, with an operating temperature span from minus 30 to plus 50 degrees Celsius. The supplier brands this component under the LVL mark and notes RoHS certification.

The 3535 package designation refers to a 3.5 mm by 3.5 mm ceramic or moulded epoxy package, a standard footprint in high-power LED assembly that allows direct replacement with other 3535-format emitters. The 308 to 311 nm band sits within the UV-B spectrum, a region commonly employed in phototherapy, fluorescence excitation, and curing applications where longer UV-C wavelengths are unsuitable. The 12 mW optical output at 100 mA indicates a wall-plug efficiency that buyers should verify against their irradiance targets. Greenergy states that all UV LED bulbs are manufactured within one month of order and carry a two-year warranty.

Typical applications for 308 to 311 nm UV LEDs include psoriasis and vitiligo phototherapy devices, protein fluorescence instrumentation, and adhesive-curing stations where precise wavelength control prevents substrate damage. Buyers in medical device and analytical instrumentation sectors constitute the core demand for this wavelength class. The supplier lists Changsha, Hunan Province, as the shipping port and offers samples for a charge with normal lead times of five to ten days after order confirmation. Payment terms stated are T/T, L/C, Western Union, and PayPal.

Greenergy Lighting Co.Ltd is located in Changsha, Hunan Province, China, with the supplier indicating a facility covering approximately 1000 square metres. The company positions itself as a specialist in UV LED technology and describes a focus on energy-saving LED solutions. The listing carries a harbour trust tier and shows a response rate of 0.00 percent with zero average response hours recorded, which indicates no response data is available through the platform. The supplier does not disclose year of establishment, employee count, revenue figures, or named client organisations in its profile.

The source description states that Greenergy has suppliedCRS with workplace partners for quality control programmes and that its UV LED bulbs have been sold to reseller professionals in over 50 countries. The company claims continuous laboratory quality testing and manufacturing within one month of order. Buyers should note that these are unverified marketing assertions and should request ISO 9001 or equivalent quality system documentation, factory audit reports, and reference customers directly from the supplier before committing to volume orders.
