The output of the lamp can be regulated by the dim switch 
on the bottom of the fixture. The typical output of the lamp is 
1000W, but it can be adjusted to 600W, 750W, 825W, 1000W 
and 1150W by putting the switch to the required output setting. 
Dimming can be done during operation of the fixtures. 

The fixture is equipped with soft-dim which gradually changes 
the output to the new setting. This takes 60 seconds per step. 

Before you dim or boost your DLI 1000W DE lamp, make sure 
that you have run it at least for 100 hours at nominal level 
(1000W) to stabilize the lamp.

The dim-switch can also be set to controller. This should be 
done when the DLI DE 1000W fixture is connected to the DLI 
Controller. Please read the instructions of the DLI Controller 
first before connecting the fixtures to the DLI Controller.

DLI fixtures come with a LED indicator: See below for blinking 
sequence info.

Hanging distance

You need at least 3 foot or 90 cm distance between the fixture 
and the plants. To check the height, place your hand (palm 
down) over the plants. If your hand got too warm, you need to 
move the lamp higher because than it is also too hot for your 
plants and you will burn them. 

Warranty

Returns

Dutch Lighting Innovations only uses high quality components. 
Under normal operating conditions, the mechanical and 
electronic components are covered by a three-year warranty 
from the original date of purchase. For service return the fixture 
in the original packaging to your shop with the original sales 
receipt. 

Components that are excluded from warranty are components 
that have failed due to abnormal usage.

In the case of defects of the DLI JOULE-Series 1000W DE 
fixture, the fixture will either be replaced or repaired using 
new or reconditioned products or parts. If the fixture will be 
replaced this limited warranty shall apply to the replacement 
product for the remaining initial warranty period, i.e. (three) 3 
years from the date of purchase of the original product.
The 1000W DE lamps are covered by a one year warranty from 
the original date of purchase. Lamps broken due to abnormal 
usage or thermoshock are excluded from warranty . 

Broken fixtures need to be returned in the original packaging 
without the lamp in order to avoid damages of the product 
during transport.

To replace the reflector, make sure the lamp and reflector are 
cooled down. Remove the lamp first. The reflector is held by 4 
holding pins on the sides of the reflector cover (image 1).

The reflector can be taken out by carefully unlatching the top 
of the reflector from the holding pins in the reflector cover 
(image 2 and 3).
