Rated 4.4 out of 5 by 5 reviewers.
Rated 5 out of 5 by Philips 4' Tubes are great! Philips lighting bulbs are a great value and they perform as stated. I would recommend the Philips brand of lighting to all. July 1, 2014
Rated 5 out of 5 by good value 30 fluorescent tubes received totally undamaged and within a reasonable time. It also was a very good value. I shopped around and many companies won't ship fluorescent tubes for fear of damage through shipping. these lamps were VERY well packaged to prevent damage. March 25, 2014
Rated 4 out of 5 by Basic purchase, nothing special Really wasn't anything to write home about. The local store had the five 30 packs I needed. Three bulbs were not functional. Not the end of the world, but I'm not going to return 3 bulbs to the store to get less than $6 credit (time vs. money back not worth the trouble). The other 147 work great though. You never know what difference it makes until you replace the bulbs. Much bigger than I imagined. September 24, 2013
Rated 4 out of 5 by Bulbs are as expected Bulbs work. 1 was broken in package. Do not have much more to say. September 4, 2013
Rated 4 out of 5 by very good product for the price,they work better than the energy eff. type. very good product and pricing,work better than energy eff. type. April 30, 2013
