Should be.
What are your nutrient levels at? How long ago did you add the light? How long ago did you add your chaeto?

Chaeto been around for 8 months , first with a white led manufactered by finnex - a lot of growth.I added this new light 2 months ago- less growth , green color fading.
Levels : phosphate 0
Nitrate 0

I add Iodine & trace elements.

To answer your question without a doubt put the old light back and see what results you get..
You didn't state what your phosphate/nitrate levels were before so we can't possibly give you a real answer/reason other than yes that light should be able to be used for macroalgae growth..
