Pure LED 680 3.2

The Pure LED 680 3.2 is The Pure Factory's efficiency flagship, listed as Pure Led PRO 680W 3.2. The 3.2 is the point: 3,23 μmol/J, from 2.940 Samsung LM281B PRO diodes and 180 SILAN SMD3030, for a photon flux of 2.190 μmol/s.

The driver does more than dim. It simulates sunrise and sunset, so the lights ramp rather than snap on, and intensity steps in increments of 25%. It also talks to the Pure LED 2.0 controller, which manages up to 250 units at once — that is a commercial-room number, not a tent one.

The frame folds, which matters more than it sounds: a fixture this size ships and stores flat and goes through a tent door. Between the efficacy and the flux figures, this is one of the few in the catalogue you can compare on published output rather than a wattage in a name.
