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!
