LED light measurement: Determining rules in advance is essential

"Growers investing in a lighting system undoubtedly seek a system that performs exactly as promised. The post-delivery light measurement in the greenhouse serves as the baseline assessment. While it's not uncommon for LED suppliers to conduct these measurements themselves, ensuring accurate measurements can be complex. Therefore, opting for an independent specialized measurement company, such as Multi-Meet, is a wiser choice," advises René van der Sar from Orance – Grow Light Architects.

Orance, the grow light specialist for horticultural businesses, has collaborated with leading companies in the market to develop a comprehensive light measurement protocol, specifically tailored for LED. "We define the conditions for entrepreneurs when they purchase a lighting system. This not only ensures that entrepreneurs receive what has been agreed upon but also eliminates any potential for differences in interpretation regarding light measurements."

Nowadays, it is even more crucial to pre-establish the measurement methods, such as completion measurements, and determine how the results will be documented in a report. The technical capabilities of LED fixtures are continually advancing, with features like spectrum control, far-red lighting, and light dimming.

More than with HPS fixtures, the environment also influences the LED fixture. "Additionally, we often see new entrants in the market without specific sector knowledge, and they may not always be familiar with the light measurement protocols and expectations associated with an LED installation in horticulture."

No room for interpretation
In the purchasing phase, most attention is often given to the lighting plans made by suppliers, in combination with the price quotation. "However, figures in a lighting plan only have meaning if you agree in advance on how they should be read and interpreted," emphasizes René. "Where and how will measurements be taken, and when will we be satisfied? That should be specified."

When investing in LED, it is essential that you can rely on clear agreements, including the method of light measurement combined with warranty provisions, as emphasized by Orance. "We deal with these details daily, addressing every nuance. It is important for all parties involved, not always the most enjoyable task, but it is priceless.”
