Whether you decide to go for two or three layer torch down roofing will make a difference to your new roof's life. A three-layer roofing torch down project will include a base, smooth torch down and granule surface torch down, and should last for about 20 years. Two-layer torchdown roofing, with a base and one torch down layer, should have a life span ranging from 10 to 15 years. Regardless of whether you want your torchdown roofing to have two or three layers, you will have to use a base sheet.
While it can vary slightly depending on the bulb, on average LED light bulbs last over 50,000 hours. That would be almost six years if left on twenty-four hours, seven days a week. In terms of usage, if you leave your light on all day (16 hours), an LED replacement bulb would last 3,125 days or approximately 8.5 years. If you leave it on only during the evening (4 hours), an LED replacement bulb would last 35 years. Comparatively speaking, both incandescent and compact fluorescent light bulbs last a mere fraction of that. LEDs last 50 times longer than a traditional incandescent bulb and 10 times longer than a compact fluorescent.
