LED or T5 for 20g long

Okay well I know I would only need two 80 degree Par30 LED's over a 10g which is 12in deep 20in long and 10in wide and I should be able to keep SPS under that. well if I had a 20g long with the same height and almost the same width, shouldn't I only need one more Par30 LED for the tank? The light intensity would be the same throughout the tank since its the same depth so I just need one more LED for the extra 10in on the tank, right? If that doesnt work I do not want to buy two more LED's so would it be better to go with a fishneedit T5 HO 30in 96w 4 bulb fixture? The T5 fixture is only 109.99 but I have to replace bulbs every year while the LED is $240 but I only have to replace them every 10 years. Which do you think is better? Does my LED idea provide enough light?

I would say two of these are what you might want;
Ecoxotic Panorama LED Module I have two over a 55 gal. supplimented with 2 T5 bulbs and it is plenty. I use one Module and one Stunner Strip over my 14 gal. Biocube and it is plenty there also. For SPS two Modules will be great.

 

So two of these over a 20g long is enough for SPS?

 

Yes, plenty.
