Mounting Tips

Continuous flexing of rope light may damage its internal electrical connections. To avoid premature failure, mount rope light to sturdy surfaces such as wood or glass and reinforce it with a channel raceway or reflector trim of the correct diameter.

If you must install rope light on an unstable or moving surface such as trees or bushes, it is most cost-effective to use incandescent rope light, which can be replaced at a lower cost than LED rope light.

Movement of frozen rope lights may also damage electrical connections. Avoid installing or re-spooling rope light when temperatures are below freezing. The PVC tubing can become brittle in temperatures below 50 deg. F.

Note on UL Listing and Installation Safety

Please note that cutting this rope light, even following manufacturer instructions, will void the UL listing of the product. This, however, does not necessarily mean the product is unsafe.

If UL listing is an important concern for you or your organization either use the full length of the spool without cutting it or consider purchasing our shorter rope light "kits".

While encourages all creative use of rope lights, we assume no responsibility for problems arising from cutting rope light. Professional installation is always recommended.

Rated 5 out of 5 by Perfect color shade Used this product for cove lighting in a $250k theater because the light color and amount of output was perfect. January 23, 2015
Rated 5 out of 5 by Liked them so much bought them again! I bought these lights to go across my back yard and they looked so good I then decided to buy them for my front courtyard. I took out the lights along the sidewalk and outlined the whole courtyard as well as the walkway up to the front door. It looks great and I no longer lose my puppy in the shadows when I take her out at night. May 19, 2012
Rated 4 out of 5 by Lasts a year Failure rate is high...a year or so.. but the cost factor is there... April 9, 2012
Rated 5 out of 5 by Awesome Lights These are the best, most reliable, and brightest rope lights I've ever used! October 31, 2011
Rated 1 out of 5 by Poor quality product I used this product to add accent lighting to a home theater project. After a couple of months of use a section of lights in the middle of a long run failed. There is now a 2 or 3 foot section that is dark when the rope light is turned on. October 6, 2011
Rated 5 out of 5 by excellent price-very bright-great customer service I recently purchased the 5/8th superbright 150ft reel. It arrived quickly and after I installed it there was a couple of dead spots. I called customer service and they were right on top of it and sent out a replacement section. an easy splice and it looks beautiful. Thanks 1000 Bulbs! Big B July 18, 2011
Rated 5 out of 5 by Excellent Rope Lights! I purchased these lights to go in our movie room. Many of the lights that we found in the big box retail stores just cannot compare to these. Your lights are so much brighter! I also liked that we were able to cut them to whatever size we needed without having to use extra connectors. For the amount of feet you get in the spool, it's a great price, too. I highly recommend this for anyone looking to use rope lighting. Great product! June 10, 2011
Rated 5 out of 5 by we love them We love these lights and leave them under the eaves of our porch all year, for dinner on the porch, parties, card games. In the Northwest they help to brighten the whole winter. They have lasted a long time without problems June 10, 2011
