Are the home depot ecosmart true color CFL's affective at all against SAD?

I recently bought 5 of the 27 watt ones for a terrarium and aquarium I am building. It's 5500k color temp is similar to the color of the light the sun produces at around 10-11 AM and 1-2 PM, roughly. However, the manufacturer does not supply the CRI ( color rendering index ) number that many manufactures do. This number reflects the bulbs ability to reproduces colors in the same manner as the sun, 0 being as bad as it gets, and 100 being exact or perfect in doing so. It can get much more complex than this. From my experience, of about a week, they are great. The plants seem to be thriving and both the plants and the fish seem much more colorful. I hear the brand Blue Max brand and the Exo-Terra Repti Glo 2.0 do a very good job at these too. I hope that helps.
