Rated 5 out of 5 by Great Experience I was trying to order these bulbs from another website but couldn't get it to process and got no help when I called so I found 1000bulbs.com. They had the bulbs I needed and for a much better price. Shipping was fast and they arrived in tact. Their pricing was much better than the other site so I was able to order more than what I needed. Great experience. I would shop here again for all my bulbs. September 13, 2014
