Johnson LEDs are a local made COB (chip on board) style LED utilizing top bin CREE LED Diodes, Mean Well Drivers (power supplies), with quality lensing, and come complete with a 3 year warranty. They exhibit excellent PAR output and minimal color shift as a result of the diodes being ran at ½ of the maximum rate; under-driving the diodes creates a a lot more efficient light source with better color-rendering.
The CX-4 is an appropriate replacement for 315 watt Ceramic Metal Halide or 400 watt HPS for a 2 x 2 – 3 x 3ft area. As much as 6 units will also be daisy chained in conjunction with supplied cord. The lenses used in this unit are proprietary 90° lenses. The advisable hanging height for this unit is 24″ above the plant canopy to maximize growth and coverage.
