    Rated 5 out of 5 by Fast delivery and great price I'm used to pay much more for this product. I'm glad I found 1000 bulbs. They are very easy to work with! October 25, 2011
    Rated 5 out of 5 by Great Bulb These bulbs are great overall, with a very fair price. Very bright and nice clean light. They last incredibly long. We use them in our warehouse where they are on 5 or 6 days a week for 9 hours per day, and some of them have lasted over ten years. October 19, 2011

    Rated 5 out of 5 by This product is energy saving, low cost and covers a wide area of darkness Before my business use to use a higher wattage bulb, which was bigger and more costly towards my energy bill , it also was a different brand . This philips brand they have a wider ray of light, lower wattage so it's less on my energy bill.The philips brand they have a longer lifespan also. Highly recommend !!!!!!!! June 6, 2011
