One Button Between You and the Right Light Level
A simple, dedicated dimmer for growers who already have switching sorted and just want clean control over intensity. The DLI DLMini Controller manages the output of DLI fixtures including LED, HPS, CMH and UV, and is built for setups where conventional switching gear handles the on/off duty. It is a plug and play unit with one-button control, so adjusting output is a matter of pressing a button rather than digging through menus on a controller that does ten other jobs badly.
Key Benefits
- Versatile fixture control across DLI LED, HPS, CMH and UV lights from one device
- Plug and play installation with no configuration to work through
- One-button operation, so output changes take seconds mid-cycle
- Pairs with existing switching gear, leaving your timer or contactor to handle on/off
- Fine output adjustment for matching intensity to the stage the crop is at
Excessive Stretch from Light Levels You Cannot Trim
Running a fixture flat out from day one gives you excessive stretch in early veg and scorched tops later in flower. Without dimming you are stuck raising and lowering the light, which changes coverage and leaves the canopy edges dark. The DLMini lets you drop output for young plants, then bring it up as the canopy fills.
How to Use
- Connect: link the DLMini to your DLI fixture using the control connection on the driver
- Keep switching separate: leave on/off duty to your existing timer or contactor
- Set output: press the single button to step the fixture to the level you want
- Early growth: run lower output over cuttings and young plants to limit stretch
- Flowering: step output up as the canopy fills and demand rises
- Hot weather: ease output back rather than switching lights off
