Crescience PAR database

We put our LED products through their paces under real conditions. The measurements take place in a closed test environment. In contrast to tests in an integrating sphere, the results are therefore subject to losses that are also present in a normal installation environment. For example, reflection losses on the walls and the power loss of the power supply.

Grow LED PPFD Measurement
PPFD test of a FLUXengine x4 setup - "The Halo

Why measure PPFD?

The most important factor when designing a LED system for horticulture is the performance of the fixture.

There are two approaches to this: Laboratory tests that integrate the photon output. These have the advantage of a high degree of standardization and thus enable a very objective comparison of different plant lamps. However, a high measured photon output in a Integrating sphere not necessarily that this luminosity is actually available for the plants in the area under cultivation. The indicated PPF values are therefore of a more theoretical nature.

We therefore perform standardized field tests and measure the photosynthetic photon flux density (PPFD) in a measurement grid. In this way we make visible how much light (PAR) actually reaches the plants and, above all, how the intensity is distributed.

The ultimate goal is not to whitewash - with our PAR test system we deliver minimum values which the user can exceed with a high probability in reality. Our test standards are transparent!

Test standard for PPFD measurements

Automated setup for PAR measurement. White coated HDF boards on walls and top, floor matt black.
The test setup currently allows measurements on surfaces with side lengths of 60, 80, 120 and 150 cm.

The effective usable radiation of a plant lamp depends strongly on the distance. We therefore measure different distances in order to the ideal hanging height to determine.

Unless otherwise specified, the lamp is placed centrally above the surface.

Apogee SQ-520, a widely used Quantum Meter that is appreciated by many users for its reliability and repeatability. The sensitivity reproduces the PAR spectrum from 400-700 nm quite well.

Crescience PPFD database 1

The power consumption is measured at the socket (input power of the driver). Electrical losses are therefore already taken into account. If possible, color channels outside the PAR range are switched off (concerns far red/infrared and UV radiation).

Old test series

PAR tests in a Homebox Ambient Q100 with manual measurement in 10 cm increments. Black floor, white walls.
