I've used the FAQ thread calculator to find out my light is low light, as in the lowest of the low.

However, I've had some pretty amazing growth from my Echinodoris plants, and my Rieneckii are starting to turn red and purple. I am also getitng algae, but I think that is due to my 10-12 hour photoperiod and overstock. I've sold off some fish and lowered that to 8 hours, and up my Excel dosing.

So I am curious if someone can help my better understand how to interpret the specs of my light in terms of the aquariums hobby.

A few pics

Tiger Lotus. New leaves 1.5 per week. Staying low for some reason.

Reineckii. When I bought it had big, green leaves spaced apart. Now it's growing tighter and much more red.

This Melon Sword had all green leaves with oval shaped. Now it grow leaves that are brown or red and elongated with points.

Ludwigia Repens? Growing very tightly now with reddish and pink leaves.

I thought they were showing signs of lack of co2 and nutrients but I didn't think lighting is a problem right now.

you don't mention your tank dimensions or light placement.
Depending on that your light can be from high to zero...

for a fun comparison..

Lumens don't include delivery efficiency, just gross output..

Here’s The Catch…..What Is The True Output And Where Does That Light Go?

The fluorescent lamp is an omni-directional light source, shooting light in every direction, and only 1/3 of that light directly lights it’s intended surface. If the tube is mounted in a troffer and even larger portion is reflected within the fixture and really never leaves it. LED is a directional light source. It’s lumen output is measured outside the fixture or once the light actually exits the fixture. It’s usable light that is directed towards it’s intended surface vs. scattered and lost from the fluorescent source.

Tank is 16" tall, light sits directly on glass top.

Edit: Took me a minute, but I see the point you are making with the chart.
