The Adjusta Watt 720w Retro LED Grow Light is a full spectrum, dimmable LED plant light designed for hobby and commercial growers. Designed for up to a 1.5m x 1.5m area for full coverage. The Adjustawatt Retro LED Plant Light is designed to replace a 600w or 1000w HPS High-pressure sodium traditional grow light. 

Features 

The Adjusta-Watt 720w Retro LED has no driver and is instead powered by a Digital Ballast (the ones traditionally used for 600w HPS lamps), making it possible for the end user to save money on the initial cost of the fixture by using their existing ballast. Don't have one? No problem! Just select a Ballast option from the drop-down menu above. When connected to a 600w digital ballast and mounted at 15cm above the canopy, the Adjusta-Watt® Retro LED produces an average PPFD of 1231?mol/s/m². That’s over twice the growth light than that of a 600w HPS, for the same power consumption!

This highly efficient fixture provides vastly more light than HPS equivalents. Users can manually adjust the output using the dial on their digital ballast. It has passive cooling due to its wide area of coverage meaning massively reduced heat. The evenly spaced light bars provide consistent coverage of good light levels at the canopy. It is silent with no noisy fans or moving parts.

Please note: For owners of other digital HPS ballasts, we advise that you buy a genuine Adjusta-Watt ballast together with the LED Grow light so you are not disappointed if you find your ballast is not compatible with the grow light, as some ballasts may use a different frequency.

Independent Testing

We've taken some PAR measurements in-store with this light, to give you an idea of what intensity levels can be achieved at various power settings and hanging heights. Measurements were taken in an open room without reflective walls, with the distance measured from the centre of the light at bar level.
