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.

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.

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.

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.
