Spectral Measurement Devices

Leveling the playing field for the LED industry.

Millions of LED products are bought and sold everyday, but not all LEDs are created equal.  UPRtek produces handheld  and portable spectral measurement devices, and we aim to bring this specialized technology to all and assist LED companies in producing, buying and selling with integrity and confidence.

The Importance of Mobility, Practicality

From this …

It’s not feasible to setup laboratory instrumentation at remote locations to measure and validate light quality (e.g.  offices, showrooms, production lines, exhibition or stores).

So mobile or portable light measuring devices have become an indispensible tool for companies and organizations manufacturing, buying, selling and researching LEDs.

To this …

Leveling the playing field: Confidence, Integrity, Trust

High precision spectral measurement instrumentation is often confined to laboratories and research centers. UPRtek’s 10-year endeavor has been to transform this out-of-reach technology and make it cost-effective and available to all industries. This means manufacturers produce with confidence, sellers sell with integrity and buyers buy with trust.

Helping LED Manufacturers make better products

LEDs remain an inexact science because of the nature of the LED semiconductor materials.  In effect, it’s difficult to maintain light quality consistently across all products, batch after batch.

We focus on helping manufacturers tighten up this LED-room-for-error by providing efficient, practical solutions in light spectrum measurement, testing and calibration efforts.

This means selling your products with more confidence, more precision, and consistent light quality for your buyers.

Helping buyers make better decisions with Spectral Measurement

Buying LEDs can be a subjective, tedious, sometimes perilous task … lots of manufacturers, distributors, spec sheet data. By using our spectrometers, you alleviate uncertainties using real data and convenient tools that help you assess and make confident decisions, by the numbers.

Comparison tools to juxtapose products, side-by-side, both numerically and graphically. And then save to storage for later review.
