Time for LEDs?

Well just keep in mind with the LEDs is you're not going to save a ton, realistically you'll be saving 400W max and that's if you downgrade. 400W is about $100 per year for electricity on a typical light schedule. The bulbs will save you more but it'll take a few years to pay off the investment.

Next consider effect, the tank will be dimmer and the effect you get from your T5s will be lost. Essentially two Radions will be similar to to just the two halides running in terms of appearance although the LEDs will offer a more actinic feel not all colors will be improved.

Between the radions and the AIs I think the AI sols are a better bang for the buck. While a single radion tends to be compared to 2 AI sols in terms of wattage keep in mind a good chunk of the radion wattage is given to green and red LEDs which will run very low if at all. The sol blues have a good ratio of what's actually needed and would be a better choice over the sol white. The AIs also come with a mounting rack and hanging kit when purchased as a set.

Vertex is also nice and worth considering, better looking than the two above options as well.

Reds and greens are in wave lengths that do not promote photosynthesis in the symbiotic algae cells living in our corals. They are almost purely for aesthetics.
