phoenix VS marineland HQI

Different brands will burn differently. One manufacturer's 14,000K is not going to be the same as the next. All bulbs lose blue as they age, but the most noticeable difference will be in the first month.

There is no science involved in the kelvin scale... Its basically a best guess scenario decided by the manufacturer. Thats why they all look so different. The CRI index is way better. Hopefully we see it at the hobby level soon. CRI Sure made my job easier.
