I installed these on 110' of deck railing then again on a hot tub privacy wall. Total 8 rolls. Originally I looked up LED strips, wattage, etc. For some reason I thought 1 300w would run the deck railing and not even be at the 80% capacity. After testing on the privacy wall (4 full strips) the 300w converter was hot. I did some closer checking on these specific ones and realized you're looking at approx 120w per roll (4 rolls = 480w) Nobody sells a 600w that I could find so I had to re-wire and run a total of 4 300w converters. They work perfect after updating the wiring and adding the dimmer. They're bright enough you can see them during the day but at night they're actually so bright you need to be able to turn them down. FYI I used 4 of these to run them https://www.amazon.com/UL-Listed-Dimmable-Transformer-Waterproof-Outdoor/dp/B07PWPVDYL
