Zoo Med Ultra Sun Trichromatic Super Daylight 6500K Fluorescent Bulb T8 15 Watt, 18-Inch

Ordered this light for my 20Gal Xtra-High Freshwater tank, and I'm extremely happy with the quality. It's as bright as a sunny day outside in my tank now, and the live plants I have already seem to be doing better with this.

Highly recommended for anyone who needs a new Aquarium light. Will definitely order again.

Very nice product. I did not use it in an aquarium...I built a "happy light" out of it (for winter blues). Bulbs are made in Germany and seem to emit the UV spectrum as advertised; A UV sensitive bead my child brought home from school indicated this. A similar bulb, bought from a big-box pet store did not emit UV waves, despite the packaging saying it did.

I don't know about the UV waves but this bulb brings a whole new look to my aquarium. Now it is brighter and all the colors are vibrant. It looks so good that now I have to replace the other bulb to match it.

Great light for a 10 gal tank with medium to low-light plants. My plants have experienced excellent growth. Don't keep the light on for more than 9 hours or you will see algae. Planted tanks are a balancing act. Find the right amount of light, the right fertilizer, and the right stocking amount, and your tank will glow with green. This light certainly helped me achieve that. Highly recommend this light for a 10 gal tank.

Received product about 2-3 weeks, shipping was slow than expected. Item as described and very good, brighter than normal bulb which sale at local fish store. I bought 2 extra bulb just in case...noticed it's 2x the original price I bought it for ($8.35).
