Life-Glo 2 Fluorescent Light Bulbs 48" 40W T-8
Great Plant light!
These are great bulbs. I have a low tech planted tank and they provide the daylight spectrum plants need. Color temp is 6700K and provides a nice light to the eye also, no weird color on the fish and plants. My low to medium light plants thrive under this bulb. If you are using for plants, best to replace once a year.

Nice and bright
I have purchased other glo lights and this makes my tank look the brightest. I have java fern, swords and various other plants and they are do great with this bulb. Everything looks bright and clear.

The Hagen "Glo" series of tubes are really the only choice if you need a 48 inch 40 watt t-8 tube. The other companies make only 32 watt t-8 tubes in that length. These do not work as well with 40 watt ballasts - both burning out sooner and generally producing less light. The t-12 tubes available from hardware stores work, but they are also nowhere near as efficient in terms of light output.
I chose Life-Glo over other Glo tubes because of the type of light produced. It is a full spectrum tube which not only produces pleasing, accurate color rendition, but also facilitates the culture of aquatic plants - which I consider important. I believe the light tube definitely worth the price premium and use it in other wattages as well, even though acceptable substitutes do exist in the other wattages.
