“The lamp and the ballast are the
heart of the fixture, but the reflector
is the soul of the fixture.”
We’ve seen lots of similar lighting
fixtures released in recent years;
what sets the JOULE-Series apart
from the competition?
I’ve seen them come and go as well. Now
every ballast builder or lamp manufacturer
calls himself a fixture-manufacturer, but
making a fixture is a different trade.
The lamp and the ballast are the heart
of the fixture, but the reflector is the soul
of the fixture. We developed lighting as a
means for production. We made sure that
the reflector was developed to be highly
efficient, but also entirely uniform. We’ve
created an open-style reflector that will
show no hotspots on the plant, even
when the distance between the reflec-
tor and the plants is as low as three
feet. The reason no hotspots appear is
because the light is distributed evenly
over the canopy instead of focused
downward like most fixtures on the
market. The fixture itself is made to be as
compact as possible, with a built-in spirit
level, to assure a perfectly even light
spread. We also developed an easy-to-use
controller that can take up to 1,000 lights
per unit on four different zones.
So, if our readers have invested in a
generic fixture are there any tell-tale signs
the product might be substandard?
Any light fixture will help growing plants.
A candle would even help growing plants.
We are focused on efficiency and bringing
light efficiently towards the plants. We’ve
researched the best spectrum for growing
and made sure to supply the most effi-
cient lamps with our JOULE-Series fixtures.
We’ve focused on temperature manage-
ment of both lamp and electronics to
assure a long lifespan.
If you combine spectrum, energy-use,
and uniformity, it could mean replacing
generic fixtures with the JOULE-Series
could make your grow about 50 per cent
more efficient and the quality of the
plants would be remarkably better.
What can you tell us about your
DLM-4 Zone Controller; how is it
different from existing controllers
on the market?
The DLM-4 Zone Controller is specially
designed to set up a daily lighting
management system for your Dutch
Lighting Innovations JOULE-Series
fixtures. The DLM-4 Zone Controller can be
connected to up to four separate zones of
DLI lighting fixtures. Each controller can
control up to 2,000 lights. Once connected
to the fixtures, the controller will monitor
and control the lights using a digital
time-clock. Up to four separate tempera-
ture sensors can be connected that will
measure the temperature of up to four
zones/growing areas. The user can select
to dim the lights if the temperature goes
above their chosen set-point, or to turn
the lights off. Each fixture comes with a
cable-set so that it can be connected to the
controller. In the coming months we will
be launching a full climate control system.
In addition to the lighting, it can also
control CO 2 , temperature, and humidity.
