ParfactWorks WF420 is a 420 W WingFlex foldable 8‑bar LED grow light designed for tents, low rooms, and rack setups. It delivers a full spectrum using Samsung white diodes with Epistar 660 nm red, plus 730 nm IR and 395 nm UV. The fixture produces 1,176 µmol/s at 2.8 µmol/J, covers about 6 x 3 ft for flowering (up to 7 x 4 ft veg), and is dimmable 0–100% via onboard control or an RJ11 master controller. The IP65, fanless, passively cooled design uses a built‑in UL driver and supports daisy‑chaining of many fixtures. Physical size is roughly 22 x 42 x 1.77 in and weight 16.1 lb, with a rated lifetime over 100,000 hours. ParfactWorks suggests 36 in seedling, 18–24 in veg, 12–18 in flower.
