The 100W replacement, for example, achieves a highly creditable 100 lm/W – delivering 1,650 lm from 16.5W. What makes this remarkable this is the 2,700K (warm) white version, with a CRI of 85, and the bulb is dimmable – dimmability can cost up to 2W of consumption. The naturally more efficient 5,000K (cool white) version creates 1,700 lm from 15W – 113 lm/W. This is one of a portfolio of 25 new incandescent replacements aimed at delivering “on the true promise of LED technology to make lighting better than it was before”, said Cree “Most are projected to last 22-plus years, and some up to 32 years.” Rated life of both bulbs above is 15,000 h, operating in environments between -25 and +45°C. Amongst bulbs, there are also 40, 60

The operational life of current white LED lamps is 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of an led lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. If the lighting device needs to be embedded into a very inaccessible place, using LEDs would virtually eliminate the need for routine bulb replacement. There is no comparison between the cost of LED lights vs. traditional incandescent options. With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labor expense and time needed to replace them. These are significant factors, especially where there are a large number of installed bulbs.

1. Long Life - LED Lighting Features Long Operational Life Time Expectations Long life time stands out as the number one benefit of LED lights. LED bulbs and diodes have an outstanding operational life time expectation of sometimes up to 100.000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. If you leave on the LED fixture for 8h per day it would take around 20 years before you’d have to replace the LED bulb. LED’s are different to standard lighting: They don’t really burn out and stop working like a standard light, moreover the lighting diodes emit lower output levels over a very long period of time and become less bright. 2.
