Most all MR16s are low voltage, which requires a step down transformer. Many older step down transformers do not work with LED MR16s because there is not enough wattage to activate them. Here are some solutions: Get various LED MR16s from various manufacturers, because some may work with existing transformers.If one transformer drives several MR16s, then often keeping one halogen or halogen infrared MR16 in the circuit will work.Get new transformers that are designed for LED MR16s.If using track lighting, get rid of transformers and MR16 track heads and get new line voltage track heads; use LED PAR20s, PAR30s, or PAR38s.

The experiment utilized a self-designed acquisition device, as depicted in Fig. 4. The device featured a black belt as the background, and a LT05114-12 V-100w-MR16 halogen lamp served as the lighting source. The lamp was securely attached to a lamp holder base, and the angle of the lamp could be adjusted by modifying the angle of the holder. An optical fiber probe with the specifications 1SMA1s-SI0.6–1.5 m was utilized. The probe was equipped with a bracket to ensure its stability and to enable the adjustment of the detection angle and distance between the sample and the probe. Spectrometer employed was an Oceanview-optics-usb-2000+ model. The optical fiber probe received the Vis-NIR wavelengths reflected from the samples and transmitted the data to the spectrometer, which was connected to the computer via USB interface. The Oceanview software to accompany the spectrometer was utilized to collect and display the sample spectrum data in real-time on the computer window.
