Is there a comparison chart between LED, incandescent, halogen and even compact fluorescent lighting?
The answer is not easy and here is the reason why:
A bulb containing for example 4 LEDs can produce a luminous flux from a few tens of lumens to about 350 lumens depending on the used LEDs.
And also if you say that a product is using Cree LED, it is not anought, because you have many types of Cree LED. This depends on the quality of LED used in the lamp (3 mm, 5 mm, 8 mm, 10 mm, straw hat LED, Helmet LED, superflux, high power, Cree Led, Edison, Bridgelux, Epistar, Everlight, SMD, etc....), on the power of the LED (from a few micro-candelas up to about 100 lumens), on the beam angle (5 to 150 or 360 for the latest), on the color of illumination (red illuminates very little while green is very powerful, warm white will be less powerful than a bright cool white), on the power given to the supply (sub-feeding a LED increases its lifetime while reducing its lighting power, overfeeding a LED gives more lighting power to the detriment of a shorter lifetime) etc..
