The Lazerlite PRO 720W is The Pure Factory's professional bar fixture, catalogued as Lazerlite Pro 720W 3.1 for its efficacy: 3.1 µmol/J. It carries 2340 Samsung diodes plus 216 red 660nm SMD2835 LEDs aimed at the flowering phase.
Two things separate it from the cheaper 720W option. The power is split across Letron 2x350W drivers rather than one, which lowers the load on each; and The Pure Factory claim a more uniform PPFD without the central hot-spot a single-board fixture tends to throw.
It covers 150x150cm and weighs 6.25 kg — light enough for tent poles at that footprint, which is not a given in this class. Bar fixtures spread their weight and their light the same way, and that is the argument for one.
