Question: does this unit have a motion sensor built in?
Document: i ordered two of these nice looking lights. installed, the both worked great at first. in about six months, however, one stopped working altogether; apparently as a result of a bad ballast (which is a pain because it took a call to the electrician to really figure out the problem).
excellent product but a little hard to install since the mounts don't work - the distance between the 2 holes do not fit the junction box. you will need an additional bracket (not provided) and two persons to mount this light fixture. I like cool white but the 2 fluorescent lights provided give a yellowish light that simulates natural sunlight. Perhaps this is more pleasing to others but I had to change them to cool white for my study.
Went up easy. Looks better than the one that was up there. Let's hope it lasts as long as the last light
We love it, we currently have the same light in the bathroom and it is wonderful as well !! !, wonderful purchase ! !
We are redoing our home using a very modern motif. We chose these lights for some halls and even closets (low price again).They truly have changed the drab look of these rooms into an elegant atmosphere along with our other lighting. These just went so perfectly with the decor they just made the room even classier. Also, they put out a nice stream of light.I would buy more of these without hesitation.
This said, the light itself is nice.
This ceiling fixture installs easily (with two people) and has stylish looks. It appears to be well designed with a large internal starter/ballast. One of the two bulbs was not functioning so we had to get a replacement (they seem to be commonly available) before we could tell if it was the fixture or the bulb - a nuisance.We were so impressed with the brightness that we ordered two more for another house. They seemed to have improved bulbs.
This ceiling fixtue was not all I expected in brightness and  clearness  I needed for my work area. This is more for decorative lighting rather than my intended purpose. The fixture is absolutely beautiful and would add to any relaxed area decor.
There are a lot of companies out there that need to take customer service lessons from American Fluorescent.
The light looks good, puts out a lot of light. After 4 months the ballast failed which is an all too common problem in two bulb circline fixtures. I called American Fluorescent about the problem with the ballast, no questions asked, a brief less than a minute phone call and they had a new ballast on the way which arrived 3 days later. I can't say enough about American Fluorescent's telephone customer service. They are polite, on top of it, and immediately respond to your concerns.
