My daughter was having her wedding reception in an open air pavillion and wanted to have globe lights hung from the center rafters as well as along the open sides of the pavillion. I ordered 8 strands of 25 feet for the perimeter and 2 strands of 100 feet to hang across the center rafters and 400 bulbs. The only other lighting in this pavillion, which was approximately 80'x 40', were two small chandeliers. I received them all in a timely manner and not even a single bulb was broken! My son-in-law and I personally installed the lights, putting the strings up first and then screwing in the bulbs, as I read somewhere. Not a single bulb broke. Fantastically, the amount of light from these bulbs totally lit up the pavillion and we only had 1 bulb out of the 400 burn out. These bulbs are no more fragile than a regular light bulb and if you use reasonable care installing them you should have no trouble with them breaking. The price for these bulbs and light strands was impossible to beat. We were able to buy all of this lighting and install it for one half of what it would have cost to hire a professional company to rent lights and install/remove them and we owned the lights after the event was over. We even gave some of the lighting to family and friends who because they were so impressed. Most importantly, my daughter was thrilled with the ambiance these lights created for her wedding.
