Who UPRtek is

UPRtek is headquartered in Taiwan and was established in 2010. It describes itself as “a manufacturer of portable, high-end spectral light measurement instruments.” The range includes handheld spectrometers, spectroradiometers, spectrophotometers, imaging colorimeters and calibration tools.

What we list

The MK350S Premium handheld spectrometer is on our light meters page. A spectrometer records how much light arrives at each wavelength, rather than one lux number. That lets you calculate spectrum-based metrics, not just visual brightness, and compare how much blue content different bulbs or lamps really emit.

Who it suits

This is a professional instrument for lighting designers, researchers and specifiers. For checking whether a light therapy lamp hits its rated lux or whether a bedroom is dark enough, a budget lux meter does the job at a fraction of the price. A spectrometer is worth it if you compare bulbs by spectrum or need data you can publish. See our guide to the best light color for sleep for why spectrum matters, and how many lux do you need for brightness targets.
