Adjusta-Watt® Retro LED

Option: Adjusta-Watt® Retro LED 720w NO BALLAST


We’ve removed the driver, meaning the end user can save money by using their existing 600w digital ballast.

When connected to a 600w digital ballast and mounted at 15cm above the canopy, the
Adjusta-Watt® Retro LED produces an average PPFD of 1231μmol/s/m2. That’s over twice the growth light than that of a 600w HPS, for the same power consumption!


Using the Adjusta-Watt Splitter Cable, it’s possible to power two Adjusta-Watt® Retro LEDs and

cover twice the area using just one ballast. The splitter cable divides the power evenly between the two

fixtures but also reduces the current, thus increasing the efficiency to 2.8μmol per fixture. The average

PPFD is now 710μmol/s/m2. This is 10% more growth light, per m2 than two 600w light kits, at half the

running costs!
