Lumens, PAR, PPF, and PPFD: Measuring COB Grow Light Output

January 11, 2017 / LEDgardener / 11 Comments

Want to figure out how much light your COBs are giving your plants? Getting an accurate measurement is a little trickier than you might think.

A quick glance at your standard COB data sheet will probably show you one related specification: its luminous flux rating. While luminous flux is a good indicator of how bright a COB is at a certain wattage compared to others, it’s not the ideal way to quantify how much light your plants are getting. There are many different units and methods used for measuring light, like luminous flux, lux, foot-candles, PPF, and PPFD. Let’s have a lil’ gander at each.

COB LED Basics: A Beginner’s Guide

After sifting through my posts, I realized that I’ve neglected to write something that’s a little more suitable for somebody who’s brand spankin’ new to the world of LED COBs. This guide will serve as a short introduction to the basic elements of COB LED lighting systems, and is a good place to start if you’re looking to make the switch from other types of lighting, or if you’re new to indoor gardening altogether.

COB LED systems are actually quite simple – there are only a handful of different parts, and they all go together pretty easily. The main components of a COB LED system are:

The COB LEDs themselves
Heat sinks that the COBs are mounted to
LED drivers that power the COBs
The wires that interconnect the COBs and drivers.

Not so bad, right? Let’s delve a little further in.
