t5 lighting question

[LifeOfAquatics]

would a t5 light like this one https://www.bulkreefsupply.com/aquablue-azure-t5-giesemann.html work fine as a standalone and the only form of lighting in a mixed reef tank? I want to eventually keep sps and my tank will be a 20 long. also, would any light fixture that fits work for that bulb? i only plan on having that one bulb. also, will I need to have some distance between the fixture and the lid of the tank or can i just put the fixture directly on like a glass lid? thanks in advance.

I recommend a mix of bulbs but thats my opinion. A lot run 2 coral+ and 2 blues
