SuperCDMS at SNOLAB is a direct search experiment for dark matter, targeting dark matter particles with low mass ($\leq$ 10 GeV/c$^2$). In order to achieve the projected sensitivity, a lower background, in addition to lower threshold energy, are a necessity. In the past, detector calibration was performed using radioactive sources. Currently, we are exploring the possibility of using LED-based calibration methods. In my talk, I will discuss measurements using LEDs of various wavelengths operated at cryogenic temperatures to study the detector stability. Moreover, I will report the progress made using this new method for detector calibration.
