LEDs are going to provide the best color from your corals in general. Best Brands are Radion, Ai, Red sea, Orphek, and Kessil imo. Radion will be best choice for SPS, they put out the best par output, are a higher quality build and have dense matrix LED bulbs which gives the best light output. Only cons are they are one of the most expensive and are a little more difficult to control unless you get the Gen 5s which can be connected via Mobius (app). Ai is similar to Radion in that you can control each color intensity individually and it is able to keep SPS easily. Ai is slightly lower quality than Radion but also significantly cheaper and imo easier to control and work with their app. Red sea lights are good if you are new as there are a few settings on it and that's it, its not as controllable as AI or Radion. They are about the same as Ai. Ai uses a diffusor plate in their led build, Radion uses dense matrix leds, Red sea is like a combo of both designs. Kessil is a great light for showing off coral but it doesn't seem to grow it as well as other brands. Kessil is not really cheaper than AI or red sea, doesn't have an app to control it easily, and doesn't have a vast array of color diodes. Kessils are also not the best option for SPS. Kessils do have a shimmer effect that is unlike any other light on the market, so corals do look great under them however. Orphek is like most off brand Chinese black box leds but, imo the highest quality of its class. Black box leds or LED Strip lights in general will keep most easier stuff alive and looking good but, will burn coral if its too close to the light. Hope this helps.
