UV light has been used to for disinfection for decades, but with the recent rapid spread of COVID-19, testing and usage of UV light has become more widely accepted. UV light can be both natural and artificial including:

One study finds a shocking number of bili blue light therapy systems did not meet the minimum recommended spectral irradiance for intensive PT

Due to the obsolescence of the Ohmeda BiliBlanket Light meter, many users of GE bili-blue light sources have reached out to ILT.  The concern we kept hearing was finding a solution to measure their lamps, and also obtain repeatable light intensity measurements that match their procedures based on the Ohmeda BiliBlanket light meter.  This is a cr

International Light Technologies is pleased to introduce the ILT750 Bili Light Meter, for measuring light sources used in treating neonatal jaundice. The ILT750 completely changes the way healthcare professionals validate irradiance values and verify the dosage of their bili pads, bili blankets, and bili lamps

In the age of COVID-19, more and more people are turning to UV-C light as a means to disinfect everything from surfaces to surgical instruments.  As we've highlighted in other blogs, UV-C light provides a great method of disinfection against infectious diseases and viruses, without the drawbacks and after effects that accompa

In the age of covid, businesses, building owners, facilities managers, and the like are scrambling to find ways to disinfect surfaces that people come into frequent contact with.   In the US alone, millions of elevators transport billions of passengers each year.

Light has been used in a host of applications including medical, industrial, agricultural, and manufacturing processes for decades.  In these applications light provides more than a means to see by.  In these applications light is used to generate a reaction.

The recent outbreak of Coronavirus has left many hospitals and healthcare facilities scrambling to extend the use of their PPE through disinfection. To that end, many are looking at using UV-C light in order to disinfect materials and surfaces of viruses and microbes .  

In an effort to fight against COVID-19 and other infectious diseases, International Light Technologies is offering calibrated ISO/IEC 17025:2017 accredited and NIST traceable UV-C light measurement systems.  

We have a brand new Super K2 LED Sign Retrofit System video demo overview from Joe Reis, Director of LED Signage.    In this video, we offer a walk through of how easy it is to use the Super K2 product and discuss the benefits of retrofitting your sign cabinets.  

If you recently purchased the ILT2400 Hand Held Light Meter from International Light Technologies, be sure to watch the latest overview video from Jill Fowler, Director of Light Measurement Systems.   This video discusses:  

At International Light Technologies, we have been manufacturing high-performance spectrometers for over 50 years. Our products are trusted by big brands such as Intel, Johnson & Johnson, and HP.  

International Light Technologies has over 50 years of UV measurement technology and expertise with the release of the all New ILT800 CureRight Profiling Radiometer.

A Spectrometer measures light similar to how a camera takes a picture. The spectrometer takes a quick snap shot of the light and provides an image (or graph) of the light output.

Do I need to re-calibrate my light measurement system (light meter)? Let’s start by saying the real question is not “if” you need to calibrate, but “when” or how frequently you need to calibrate.

As the costs of LED sources declines and the performance improves, LED products are rapidly being adopted for general illumination applications. This is a positive development in terms of energy consumption, as LEDs use significantly less electricity per lumen produced than many traditional lighting technologies.

Can there be a more important light source in our lives than the Sun? Not likely. Just a giant flaming ball of gas at the center of our solar system. But the Sun is so much more than that to us: it heats our planet, drives the weather and ocean currents, keeps Earth from spinning out into space and provides us with food.

Miniature spectrometers discriminate the wavelength based on the position the light hits at the detector array allowing the full spectrum to be obtained with a single acquisition.

Starting in the late 2000’s, convenience stores, grocery stores and other retail establishments were replacing their existing fluorescent lights with more efficient LEDs. Fueled largely by rebates from utility companies and the promise to slash energy costs substantially, these establishments couldn’t replace their fixtures fast enough.

We are excited to participate in the upcoming RadTech 2019 Conference & Expo in Redondo Beach, California on March 19th

We are thrilled to be a part of this year’s SPIE 2019 PHOTONICS WEST conference. Be sure to stop by our booth #2532 for live product demonstrations of our latest light measurement systems, including spectrometers, radiometers, lux meters, light meters, integrating spheres and more.

LEDs offer many advantages over traditional lamps LEDs are everywhere!

As the world’s population continues to expand, so too does the demand for goods; and the world wants them fast and cheap. To keep up with the increase in demand, manufacturers are constantly looking to increase their output by shortening the production time while keeping costs low.

One of the most damaging events to the incandescent lamp is the water cycle. This can occur with even the minute amounts of moisture (water) remaining inside the lamp glass during the production process. When the temperature of the environment exceeds 100 deg C the high temperature breaks the water vapor down into hydrogen and oxygen.

International Light Technologies has been featured in the newest study published on Nature.com on artificial light at night.

In our newest 3-minute video tutorial, Jill Fowler, Director of ILT's Light Measurement Systems division provides a walk-through of what cosine correction is and why it is important.   This video covers topics including:

What is an ISO17025 accredited and NIST traceable calibration and why is it important?   Most light meters read out in empirical units such as lux, foot candles, watts per square centimeter, watts, etc.  But not all systems that read out in the same units have the same quality of calibration behind the values.  

A UV meter is also often referred to as a radiometer, optometer or light meter. It is a tool capable of measuring the absolute (calibrated) amount of light power within a certain portion of the electromagnetic spectrum, called wavelengths.  

Most NDIR miniature and sub miniature vacuum lamps are rated for 5V, AC, continuous operation. Lamp life ratings are determined by measuring a very large batch of lamps and recording when 50% of the lamps fail to illuminate.

Employee health and safety in the workplace is a paramount issue for employers, and is regulated by the government.  Employers are required to provide a safe working environment for their employees and visitors.

ILT produces a number of custom LED lighting retrofit solutions every year, many of them for companies in the commercial/retail sector. This custom LED lighting solution involved improving the overall lighting of retail cosmetic display cases in hundreds of drug stores across the USA.

A researcher recently contacted ILT with the following UV measurement application:

International Light Technologies (ILT) was contacted in early 2016 by a local electrical contractor, M-Raz Electric, to assist with some unique architectural lighting applications on a new, high-end ($2M+) home in Winchester, MA.

Below is a recent inquiry from a potential customer looking for more information on making a particular light measurement:
