  • Other LED Configurations Include Unmounted LEDs in TO-Can Packages and LEDs on Metal-Core PCBs (See LED Selection Guide Tab) 

Light-Emitting Diodes (LEDs) are compact, energy-efficient light sources that can emit light over a wide range of wavelengths. Thorlabs offers LEDs with single-color and white-light wavelengths. These LEDs are epoxy sealed for protection. The white-light LEDs have a phosphor coating on the surface of the device that converts the 450 nm light emitted by the LED into white light. LEDs in stock come in packs of 20, packaged within a plastic reel as seen in the image above.

All the LEDs sold on this page are packaged as a surface mount device (SMD) for use in OEM manufacturing applications; the LED must be soldered onto a circuit board with an appropriate heat sink (up to 1.2 W heat dissipation) in order to be used. For laboratory applications, Thorlabs strongly recommends our large selection of pre-mounted LEDs because of their ease of use. For a full list of all our LED options, please see the LED Selection Guide tab. To discuss other options, please contact Tech Support.

LEDs are sensitive to electrostatic shock. Please take the proper precautions when handling the device; see electrostatic shock accessories.

If you do not see an LED with the wavelength/color desired, please contact Technical Support, and we will work to obtain one for you and consider adding it to our permanent offerings.
