Yes, but allow me to clarify a bit. The kelvin, which is the colour temperature of light, is the important issue with 6500K, "daylight" as most manufacturers term it. This is ideal plant growth light, and it also provides a true rendition of fish and plant colours.
The intensity is another matter not directly related to the K although it is true that tubes in the 6000K-7000K range are (in my experience with them) fairly consistent in their intensity.
