Go to the "Migro" page on YouTube and search for your light. They do great reviews and testing of lights so you can see how yours compares. They also have videos explaining light measurement and what the different (PPFD, LUX...) units mean.

Also, you may be confusing µmol/m²/s and µmol/J. µmol/m²/s is the measurement of photon flux (PPFD) on a light meter that can measure PPFD (actual growing of the plant). µmol/J is how efficient the diodes are (electricity bill related) as I mentioned in my previous comment.
