Fiji Sun T5 4ft is cheaper than 3ft

[Ezduzt_nyc]

Buying 100 gallon, 4 ft tank. Going to start a Softy tank with fish and LR, and want to be able to expand to other coral types in a year or two. Was originally looking at the Hamilton FijiSun 3ftx6 lights, and now see that the 4ftx6 are on sale $50 cheaper. Now I'm wondering if I should buy the 4ft instead?

Any advice is greatly appreciated.

If your tank is 4 foot go 4 foot.
