Cost to Benefits and how to calculate them

LED replacement bulb: - The cost to benefits of replacing a regular incandescent bulb with a LED bulb and how to calculate that benefit

Over the course of the next 7 years you will save $$ about 97% on powering a LED replacement bulb compared to your current regular light fixture. But how about the benefit you get from the buying price ... ?

Well, the price of a LED light bulb is somewhat high, I agree. But that doesn't mean you won't save $$, because you WILL, in fact.

Why you aks? Well, let's see then: - For a LED light bulb you fork out say $35 on average this year (2008), true.

But when you add the price of the additional 59 regular light fixtures that you WILL also need to buy to replace a 67cent regular bulb in the same 7 year period just ONE LED light bulb will suffice - what happens then?

You actually get a price higher then the price of that one LED bulb.

You will find that running a regular bulb is insanely expensive!

So the overall cost a LED replacement bulb drawing a total of 120 kW power for about 7 years (6.85yrs, 17.5 kW/yr, 10cents/kW) is say $12 plus the price: $35. All up $47.

Compare that to 60 bulbs using 97% more power (525.5 kW/yr) at the same cost: comes up to $360 PLUS 60 times(!) 67cents -- this for the price of the 60 bulbs used in the same period of time:

All adds up to $400.20!!! The bottom line is that you pay $47 for a LED bulb vers $360 for a regular incandescent bulb. How's that for cost benefit.

And the Time to Break Even?

To calculate the time in years (yrs) you will break even - time spent before you start taking profit -- the formula will look like this:




Using the above data that I tabulated below for easy comparison I have calcuted the actual break even time -- it is not even a year.

regular bulb (kW/yr)	525.5 kW/yr
power price ($/kW)	10cents
No of regular bulb used (No/yr)	8.76 No/yr
regular bulb price ($)	67cents
LED bulb (kW/yr)	17.5 kW/yr
LED bulb price ($)	$35

But the current trend WILL continue and LED prices will drop. Meanwhile, power prices will rise. Why? Because increasing demand and environmental infrastructure investments will force that to happen.  So suppose LEDs drop to half the current price and power prices double. -- With a LED replacement bulb then you will break-even 5 times faster -- in less then 1.4 months (or about 5.5 weeks.) Meanwhile the difference you will have started pocketing grows even bigger: In the same approximately 7 years you will have spent $41.5 on one LED vers a whopping $760.2 for 60 regular incandescent bulbs you would have used in the same period of time!!!

There is no point in calculating this further - you win by a large margin, whichever way you cut it. And as time passes you will win much more.

Not to mention that many fun LED devices are VERY reasonably priced. Especially if you add all the neat stunts you can do with them. Color changing without a filter. Programmability and single point color changing. And for many LED stuff NO heat at the light source itself! Which regular bulb can do THAT? The bottom line? The cost to benefits of LED replacement bulbs far outweigh the cost to benefits of a regular bulbs -- more than 8 times. And as LED prices drop and energy prices rise that ratio will increase to more than 18 times and beyond.
