Rated 3.0 out of 5.0 by DoItBetter Very Slow Start
BEWARE: This ballast is classified as "Rapid Start" by Philips, but this means it takes 1-1.5 seconds to produce any light. I called Philips tech support when I experienced this delay (with new Philips Alto bulbs), and they confirmed this is normal--the delay is also stated in the on-line spec sheet (but not on or with the product in the store). My previous ballast (older magnetic type, Universal Therm-O-Matic-X brand, also rated Rapid Start) started nearly instantly. Waiting for light as you come into a dark room is very annoying. HD is selling Philips exclusively, and Philips does not appear to make/sell any "Instant Start" ballasts for the F40T12 bulbs, so there does not appear to be any alternatives with Philips or at HD. The slow start is supposed to increase life, even though my last one, which came on instantly, lasted at least 15 years with constant on-off use. Personally, I would like to have a choice: life vs. speed (with an "Instant" start rating?). Aside from the "Rapid" rating on the item's label, the in-store literature should at least notify the buyer of what to expect--you should not have to call tech support to find out something so basic. On the plus side, if you can tolerate the slow start, it's size and weight are very convenient compared to the older magnetic ballasts, the price is relatively good, and it evens comes with a good 5-year warranty (probably, partially because of the slow start).

Make sure one gets the right replacement part. Follow the wiring in the replacement, not in what is getting replaced. School yourself on what wiring diagrams mean. Putting in was easy, you need a wire stripper and wire connectors. Rest is simple!

Rated 5.0 out of 5.0 by DonF SO far so good!
After replacing all the tubes in my office the old magnetic ballast failed on one fixture. Bought and installed this ballast. Easy to install. Notice this fixture now lights instantly with absolutely no flicker - now I will replace the others one by one.

Rated 4.0 out of 5.0 by Skip Ended up not needing it.
When I disassembled the ceiling light to install the new ballast, I found that my problem was a bad wire instead. However, the ballast would have fit perfectly and would have been very easy to install. Instructions were clear and understandable.

Rated 4.0 out of 5.0 by yogwood AMbistar fluorescent ballast
My old fluorescent fixture stopped working and it turned out the ballasts were at fault. I had 2 ballasts in my old fixture and I decided to replace them. I couldn't find any local store that carried it and so turned to HD. The ballasts came on time and I was able to install it based on directions I found on the web.
It took HD 10 days to get the product from their warehouse in OH to NJ. I don't understand why it takes so long, but outside that everything was as promised.

Rated 5.0 out of 5.0 by Richard Some Built a Better Ballast (finally)
I work in the Hotel / Motel , Condo Maintenance field and we are always replacing ballasts.
This is a newer Electronic Ballast and if you have ever had to change many of them on top of a 20 foot ladder you be be thankful for the smaller size and less weight the new ballasts have.
