Light-Emitting Diode vs High Intensity Discharge lighting

Post by grow420 »

Okay so let's break this down.

High end Led lights these days emit around 220 lumens per watt of electricity, and they produce around 3.1umol/J.

But a high end High Intensity Discharge light like High Pressure Sodium, Metal Halide, or Ceramic Metal Halide will only produce a max of around 160 lumens per watt and 1.9umol/J.

So on paper LED is king it produces more visible light and emits more photons per second than a High Intensity Discharge light source.

But keep in mind I have spoken with a number of growers that say High Intensity Discharge lights will penetrate deeper into the canopy vs LED.
