300-400W ALTERNATIVE LIGHTING TEST
300-400W ALTERNATIVE LIGHTING TEST
We’re pretty excited over here at
SPECTRORADIOMETER from StellarNet.
because we have just received our SPECTRORADIOMETER
This expensive piece of equipment will help bring our testing to the next level, beyond
measuring simply lumens or photosynthetically active radiation (PAR). A spectroradiometer
allows you to measure intensity at specific spectra over a wide range of colors and interprets
it into a graph, just like the ones you see on the boxes of HID bulbs. Lumens simply measure
light intensity to the human eye, not neccesarily the intensity of light used for
photosynthesis. A PAR meter measures the intensity of light between 400-700 nm,
yet aggregates all spectra within this range equally, as a number.
Our spectroradiometer measures from 340 to 1000 nanometers (nm). The human eye can
pick up light sources between about 390 (����) and 700 nm (���). Below 400 nm and you're
in the Ultraviolet range (UVA-UVB-UVC). Above 750 nm and you're in the Infrared range (IR).
For this test we decided to grab some of the most popular new lighting technology
available in the 300 to 400 watt range--a range we’ve had yet to test. We also included a
traditional high pressure sodium (HPS) light to the test because, of course, we were curious.
The lights tested were:
LUMIGROW PRO 325
SUN SYSTEM LEC 315
CERAMIC METAL HALIDE FIXTURE
BLACK DOG 360W LED
BD360-U
(UNIVERSAL SERIES)
KIND LED K3 L600
400W HORTILUX HPS LAMP
400W QUANTUM BALLAST
YIELD MASTER 6” REFLECTOR
FERO LED 10 SPOT
In addition to recording and graphing the spectral output of each light with the
spectroradiometer, we also measured the PAR output over a 4’ x 4’ grow footprint. Using
our Sun System PAR meter, we measured readings in 33 spots as seen on the grids in the
infographic below. We took these readings with all lights 24” above the 4’ x 4’ grow
footprint. We then plugged all of the grow light fixtures into the Kill-A-Watt meter so we
could read their wattage, amperage, voltage, and hertz. For this test we tried to collect as
much data as possible.
