Agree with @esolo16, low to medium light is fine. IME they adapt to almost anything. Mine is about as low in the tank as I could go, but I run 4x Hydra 26's across a 60" tank and at like 75% total power 20,000k color temp. So I would say mine is in moderate strength light and moderate flow. It balloons up so big it looks like it's ready to pop.
This is 11 heads, measures about 7" diameter

I have been having terrible luck with Duncans. Had small one in my 10 gallon that died and the one in my DT is closed and acting odd now too. I moved to low flow and lower light area, but still closed. I removed a pest stone crab that could have been bothering it but I'll not sure. All my other corals are thriving.

IMO well at least in my case they don't care if its low or high. I have 3 colonies all grown from single stalks in 3 different tanks . 1 is right at the top kind of a center piece 1 sits at the bottom on a shelf and a third is in the middle/top all three of them are between 30-50 heads each at this point. As far as current its kinda the same at least for me. I have one sitting close to a MP60 one that sits by an MP10 and one that gets little direct current. Duncan's are pretty hardy once established

That Duncan looks very healthy. You should start to see additional polyps sprout from the stalk if it's really happy. My Duncan and my hammer (similar in growth to a Duncan) seem to sprout a new head every couple of weeks.

With a lot of corals (like real estate) it's location-location-location [emoji6]
Just keep moving it around to different spots every few days until you see it open nice and big.
My Duncan was easy to find a spot as compared to this one toadstool leather I have. I moved that friggin thing like 10 times before it was finally happy and opened up.

They are durable. Had my colony in medium low for about 5 years. Than high about 400 par for the last 2 years. The growth in low has longer stems between heads and better color. In high the polyps are more clumped. Looks more like a giant anemone. The tentacles are also longer in high high light.

I love Duncan's. My are high up about 6" under the water surface. I run an 8 bulb ATI fixture that is 10" above the waters surface. I've had them in all kinds of light and they always adjust. Feed them. They will grow very fast.
