Macro Algae will grow under any color temperature. Although 6500k temp is a good temp. However these higher temp bulbs are a bit more expensive than the more warm/ white color temps commonly found in all hardware stores.
Sure, some macros will grow just fine under most lights. However to get the best growth you need a wider spectrum of light than nearly all reef lights supply.
Also, where are you shopping for lights? I found my 6500k cfl bulb for $3 at a local big box store. All in all my refugium light was approx $11 and costs very little to run.

If you want to grow SPS
corals then that light is insufficient. However it will suffice for nearly all soft corals and a fair number of LPS
