sorry i missed that question and thanks for stepping up rayne. i wouldnt hesitate to run the 1825s at 120w on an sst-x. it will run a little hotter and dent efficiency a bit vs lower currents but those chips are rated for 105c case temp/140C Tj.
thats whats cool about the 1825, efficiency is pretty respectable at higher wattages. that 1825 at 120W is about where a cxb would be at like 80-90W on ppfd/W. Pushin it but not too much
SSTX is a force. Its hard to recommend anything else for 80-120W
