5mm Super Bright Ultraviolet LED (350mcd, 400nm) | 5-Pack

Regular price $1.50

Whether we're artists, designers, professional makers, or hobbyists, we can't help but be hopelessly drawn to projects that emit light. Because of their low cost, safety, and easiness to operate, Light Emitting Diodes (LEDs) represent the best choice for using light in any project.

Thanks in part to the rounded lens, these super bright LED offers superior light output for excellent readability in sunlight and dependable performance. These 5mm, highly-durable LEDs provide extremely stable light output over long periods of time. The lamps are made with an advanced optical-grade epoxy that offers superior performance as well as very high resistance to both temperature and humidity for outdoor signal and sign applications.

These LEDs emit UV 'blacklight' in the UVA spectrum (datasheet) so they are great for projects with fluorescent materials referred to as UV/blacklight-reactive or 'glow-in-the dark'. They are quite bright (~350mcd) considering the part of the spectrum where they operate; the viewing angle is about 20 degrees.

They are easy to use with solderless breadboards, and typical applications include counterfeit detection (bills, credit cards, documents, etc), sterilization, pesticide, black lights, sun burn detection, and more! They come in a pack of five (5) to add more UV blinky-ness to your projects.

Please wear proper eye protection when using these LEDs!
