My vote is for Metal Halide/LED. I’ve just had the best results with it. The LED blue bars just give more of a punch than T5 actinics did.
As for LED, that mainly depends on budget. Many of the LED reef lights will be sufficient for what you want. All are tried and true
At the top price end: Radion, AI Hydra, etc.
Mid Range Price: Reefi Uno 2.0
Low End Price: Viparspectra, SmatFarm, NiCrew, Noopsyche or similar would work.
In the end it boils down to price, features, warranty and related support (or lack thereof), and ultimately coverage. In the low price point I didn’t specify models (some models will have better coverage, features, etc than others).
For example, the Viparspectra is 2 channel control and does not have an app last I knew. SmatFarm is 6 channel control but no app and as I have one of the G5 models, quite frankly the spectrum leaves a bit to be desired to really get that color “pop,” but it grows coral and anemones just fine. NiCrew, I personally wouldn’t buy another NiCrew product unless significant advancements have been made but that’s just my personal experience with the lack of control in the one light I’ve purchased. Reefi Uno has a great reputation but the app and UI can be a bit dated looking. Noopsyche has a pretty good reputation but their customer service is lacking at best.
