4x Buyer Protection

The Yield Lab 1000 watt Slim Line digital dimming ballast can run any HID bulbs (both HPS and MH) rated at one thousand watts. 1000 watts is the biggest standard ballast size and, although the Slim Line runs cooler than most, you will still need to set up an exhaust system.

A 1000 watt system will cover an area of around 4 by 4 to 5 by 5 feet and should hang around 21 inches from the tops of the plants. You can expect yield of 400 to 1000 grams.


Slimmer Design Means Lighter Weight and Cooler Operating Temperature

The new Slim Line 1000 watt ballast has a slimmer design, which means a lighter weight and a larger surface area in relation to the overall size. With more surface area for heat to disperse, the unit stays cooler than larger models, but is still every bit as efficient.


Dimmable Ballast Saves You Time, Energy and Money

The dimmable feature on Yield Lab's 1000 watt Slim Line digital ballast allows you to run your bulbs at 50%, 75% or 100% power. It also has a super lumen feature which boosts your total power to 115%.

Being able to alter the power output allows you to give your plants variable light intensity throughout the day. Yo can also reduce the lumen intensity during the early stages of plant growth and provide a higher output during the later stages.

You can reduce excessive heat during hot days and also for your own comfort whenever you are working beneath the lights, e.g. pruning or doing maintenance work to your grow area. The ability to lower light intensity also prevents burning your plants.

A dimmable balance improves your quality and control and ends up saving you time, energy and money.


The Yield Lab 1000 Watt Slim Line Ballast Can Run Both HPS and MH Bulbs

No need to exchange ballasts or even flip a switch. Simply switch out your Metal Halide (MH) bulb for a High Pressure Sodium (HPS) bulb and easily go from veg to flowering. Or vice versa.


The Yield Lab 1000 Watt Slim Line Ballast Runs Silent and Cool

The new Slim Line 1000 watt digital dimming ballast is designed for heat dissipation, encouraging the flow of air through the unit. It also has large heat sinks and internal cooling fans that drive any heat out through the exhaust ports. This ballast runs cooler than ever and is also designed to operate silently, with no humming or buzzing.
