Life-Glo 2 Fluorescent Light Bulbs 18" 15W
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.

Good plant light
I use these 20W bulbs in all of my "low to medium light'' planted tanks and find they are very good for plant growth.
