Coralife 05486 50/50 Straight Pin Compact Fluorescent Lamp, 65-Watt

When you first plug this bulb in and turn on the fixture, it will make the colors in your tank "pop," from fish to corals. Sadly, that doesn't last long, and within a couple of months it's not much better than any standard fluorescent bulb. (I really noticed the difference when I replaced one of the two bulbs on my fixture, and saw the radical difference in light intensity and hue between the new and old.)

I think for my next fixture, I'll be looking at LEDs...

Tubes give off sufficient light and duration. Only slightly cheaper than purchasing at aquarium store. In any case, these tubes are way over priced and I'd looks to see if there is not a better and cheaper technology!

Though it's the right replacement for my lighting set up, it keeps on flickering when turned on. I returned it and still waiting for my refund.
