How much lighting is necessary for a Green Duncan coral? I recently purchased a Mingdak 24 inch LED fixture. It's only 11 Watts. Would this be enough to sustain a Green Duncan coral if it's placed at the top of the tank? If not, does anyone know a cheap LED light that could supplement my main fixture?

How deep is your tank? Duncan's do well with low/med lighting and low/med flow. They also do well if fed small meaty foods periodically.
I know nothing of the lighting you're speaking of. A link would help.

As mentioned, Ducans like Med light and flow. With the light you have it may not be enough to keep your duncans happy. Mine are on the sandbed @ 250-300 Par with med/high flow and are growing like crazy. I have to frag 1x month to keep it from taking over my sandbed, I believe you need more lighting even if placed higher in tank, IMO

Look at this forum, people have lights on sale all of the time. I would go T5s if your budget allows, great color and par with ATI bulbs.

A DIY gu10-bulb based fixture like the ones I have built (and the ones profiled here) can be that cheap. Given the budget you have defined I would definitely consider building one. Definitely read at least the first post of that thread to see if it looks interesting.
As a minimum, you could build a 12" fixture just to light up that coral (building a bigger fixture later, recycling these parts into it). That would only take five bulbs (three white; two blue) and five sockets. Bulbs can be as little as $1.50. Sockets as little as $0.50, but you can easily find bulbs for $3 and sockets for $1 - still a fine deal. (Some folks elect for bulbs that cost up to $5-$7 for different reasons...somethings you can consider for that bigger fixture later.)
That's $20 in parts for a twelve inch fixture that'll grow SPS. You supply (at minimum) an extension cord and something to mount the sockets onto. (See that first thread for lots of ideas....but stick to the standard design for bulb layout.)
Also, get a [HASHTAG]#lux[/HASHTAG] [HASHTAG]#meter[/HASHTAG] so you can stop guessing about the lighting levels on your tank.

Most corals seem happy when a tank gets moderate light levels around 40,000-50,000 lux....however most corals also seem to tolerate from 20,000 to 80,000 lux very well. Many corals will be even fine with 10,0000-20,000 lux. More is almost never better...

You can presume they will love blue-heavy light and moderate flow from this....no red light that low and no sand in high-flow/high-turbulence zones.
One of the ideal reef tank corals IMO!

If those are those Amazon aquarium lights, they aren't for marine and coral growth. You need to look at something that is suited for corals.
I recommend going on eBay with your budget and buying a full spectrum led box for $80-$90 bucks. T5 was also mentioned which is always a great choice.
Again a link to the light would be nice because googling it I found just the submersible lights for freshwater tanks.

Do you have 250 to 300 par on your sand? If not, what are your readings on the sand where the Dunkins are doing so great. I’m ready to buy another Dunkin but I’m not sure where I should put it in my tank so I ordered a par meter
Not sure if you've realized it yet, but you responded to an 8 year old post.......
