What is considered high lighting?

[cgthebeast]

So I'm upgrading my plant variety and was wonder if a 2 bulb t5 24wattsx2 is considered high lighting? It's has a output of 10,000 k per bulb and could support corals on a smaller tank. My amazon swords have been thriving under it but I'm afraid if it might strangle java moss? Or that it might not e enough for alternantheta renineckii or ludwigia reopens rubin

No way to tell you without knowing the tank size and what depth it is from the lights. OS.

Oh my bad haha. It's your average 36 g bowfront with 30x 15x21

Light Level

OK thanks,
A lot depends on the quality of your fixture's bulbs and the reflectors. I'm attaching a couple of links to articles about lighting that may help you determine what your fixture may be. The old watts per gallon rule really doesn't apply anymore. But 48w total on 21" would be the lowest side of medium light IMO. Hope this helps. OS.

Well after checking you charts and such (thanks for that, I couldn't find a par chart anywhere!) I have very good broad reflectors where you can clearly see mulitimages of the bulbs. And based off theses I'm gonna say high medium lighting or low hight light close to the surface. So I have a 2 bulb T5ho with good reflectors.
