I'm impressed. You're truly well informed and very intelligent. You wrote something that people could understand and made the subject intriguing for everyone. I'm saving this for future use. vent cleaning

Problem is,


That these figures are complete nonsense...., there are far too many websites & people stating that using it for so many hours a day is the same as years of life, but that is what you get from  websites that are advertising 'shills'.

Lets take this nonsense to an absolute extreme, if I use my LED light for 1 minute a year then it will last  25,000 years....,  and if I never use it, then it will last for longer than the age of the Earth.

Unfortunately many of these so called 'experts' have no background or understanding of electronics, they fail to take into account, aging of components and industry standard mortality figures, not to mention most of these designs contain electrolytic capacitors, these capacitors are liquid based technology, as a result they tend to dry out, especially when subjected to the extremes of heat and cooling.

Simply taking the lifetime figures of a single components  and then applying it to al the other parts in a product design is ludicrous, the reality is that in its simplest form the product has a lifetime equivalent to the  component with the LOWEST lifetime in the design  minus any aging effects due to power cycling & temperature conditions.

Today  I saw a blog post on LED lights. The writer concludes that LED lights are worthwhile and likes the idea of not having to change a light bulb for 23 years: If you add this up over the 23 year lifespan of the LED bulb, it looks pretty compelling. The LED bulb would cost $20.70 to operate while the incandescent bulb would cost $110.40 over the same  23 year period.

Me too.

 But I feel this tube will be using lot of materials that is not really green. Wont the amount of waste generated by LED tube be more than a conventional tube light?

"lighting had been replaced with LED lighting, the cooling costs were reduced dramatically"


Interesting point Matt. We never consider cooling costs when we compare fluorescent lighting with LED lighting. Any idea by how much percentage the cooling costs got reduced ?
