It all depends on what you want to spend. LED's are the best Reef invention since the invention of water ( yeah I know..took that a little to far lol ) BUT the initial cost is higher.
A 6x48 T5 is more than enough for SPS. I have been running a 6x36 on my personal SPS tank for a few years. The ONLY reason why I'm swapping them out next month is because my F-series LED's are coming in.
So let's talk price.
48" F-series LED sells for $1,099.99
2 x radion LED's sell for $1650.00
6 x T5 48" TEK sells for $349.99 + 6 ATI bulbs at about $150, total of $499.99
The "problem" with T5 is you need to swap out the bulbs every 9 months....although I have gone 1 year with little browning. I have my T5's on a hanging kit so I lower them every few months, it extends the need to replace bulbs a little. With that being said, you need to dish out $150 on bulbs every 9 months.
Both are great lights, both will grow SPS. The question is $$?
Good luck with your purchase.
