I wouldn't recommend this fixture for a serious planted tank enthusiast. The PAR at depth for a .06W led
with no optics is pretty abysmal. Unfortunately, in the current market, a good LED
fixture for $39 is probably too good to be true.
That being said, it would probably grow some low light plants ok.
If you really want to go LED
, consider the trulumen pro, a taotronics fixture from ebay, or building a fixture yourself from parts from rapidLED.
