Simplified electronic protection circuit for LED luminaires for horticultural applications

A current conditioning system (100), comprising:

• a LED support structure (261) with a channel (264) extending therethrough;
• a first LED array module (115) carried on a first surface (108) of the LED support structure (261), wherein the first LED array module (115) includes a first LED array (101) and a first current conditioning circuit (110) which adjusts the amount of current flowing through the first LED array (101) in response to a first temperature indication;
• and
• a second LED array module (117) carried on a second surface (109) of the LED support structure (261), wherein the second LED array module (117) includes a second LED array (141) and a second current conditioning circuit (110) which adjusts the amount of current flowing through the second LED array (141) in response to a second temperature indication.
