First, of those linked tubes, the Phillips is closest but still not what i would get. I use Phillips daylight deluxe as the second tube on my three larger tanks, it has more blue (cooler) than the one linked and will in my view be better for appearance and plant growth. The Aqua-Glo you can forget; I have one, it is very weak, plus it casts a ghoulish purplish hue over the tank. The All Glass I am not sure of; if this is the same as the tube that comes with their fixtures, those are garbage, much like the Aqua-Glo. I've no idea what they are called, so this may be it. Forget it.
Check at hardware stores, including Home Depot, for the Phillips Daylight Deluxe. Preferably in T8, but T12 will suffice. The "T" number is the tube width, and in eights of an inch, so the T8 is 8/8 or 1 inch in diameter, the T12 is 12/8 or 1.5 inches in diameter. The significance here is that the T12 tubes are older, the T8 is newer design and they are more efficient (wattages are often less than the comparable T12), last longer, and generally are more intense. All manufacturers are switching from T12 to T8. But if you find the Daylight Deluxe in T12 and not T8, that will do.
Tubes must be replaced regularly, and before they "burn out." A tube loses its intensity quite fast, the T12 much faster than the T8. T12 must be replaced every year, many recommend every 6 months; T8 can last 2-3 years. I have left some of mine too long as an experiment, and while I couldn't see the weakening in light, the plants did, and algae suddenly began increasing. Replacing the tubes solved both problems.
Now to kelvin and watts. Watts first, its the easiest. It is simply the measurement of energy used by a tube to emit the light. It has no direct
relevance to how many tubes you need, though it can serve as a guide but only with T8 tubes and average tanks. It used to be that all tubes came in standard wattages for the length of tube; example, a 48-inch tube was 40 watts. But now, with the T8 and improved manufacturing, there are 48-inch tubes of only 32 watts that are equal in intensity to 40w tubes, of the same general type. This is another reason why watts is rather meaningless.
Kelvin is the measurement of the light's colour. Mid-day sun is around 5500K-6000K. A lower K number means warmer light in terms of colour not temperature, reds and orange; a higher K number is cooler, more blue in the mix. This also is somewhat irrelevant, as the actual spectrum that the tube emits is more important. However, in my experience, the tubes I have recommended have sufficiently good spectrum for plant growth. I have used these for more than 1`5 years, and you can check the photos of my tanks for the results. The colour rendition of fish and plants is also very true.
