My not so popular input:
I will take water stability and clarity over lighting, all day long. That requirement being met, you could probably keep most corals alive using old school power compacts. In 2006 I had a booming 75 gallon sps tank, lit by a tek 6 bulb fixture. At that time, I had many reefers telling me that t5's wont work, it was so much fun posting pics of my tank, beautiful, colorful acros :) Back then, many claimed sps could only thrive under MH, and use of vho's to supplement. 15 years later, now t5 is pretty well accepted for growing sps. I have never used a par meter, old school observation, and proper coral placement. Thinking ANY lighting will guarantee success is misleading and not true. For example, I have not seen a speciazed refugium light do anything that a pc, t5, or cheap 6500 k led bulb do, as far as growing chaeto. I use the latter, and am growing healthy chaeto like crazy, 25watt led 6500k led bulb from HD. Sure the red spectrum looks cool, but based on years of keeping chaeto, I wouldn't personally wsste my money on chaeto.
As far as the reef goes, SPS corsls aside, I feel trendy led lights are just that, and often used in a scenario where its unnecessary for certain coral keeping. Use them, don't use them, it doesn't matter to me, spend your money as you choose. I just find it odd when I see a 50 gallon tank with 2k in lighting, using a cheaply made chinese skimmer and pumps. Do they work, absolutely, so do their lights ;) Corals dont care what your lighting choice is, they just need what they need to be happy and grow :)
