As a matter of fact how much real benefit do you acquire from LED bulbs?

The advanced technology of LED bulbs means that they save a high amount of electricity

, on the other hand, their price is quite astronomical! The additional benefit is the especially long life so overall are they worth owning? I certainly suggest that a credible method to measure the financial cost- benefit is to look at the entire lifetime costs of LED Bulbs and compare this to the equivalent for common light bulbs.

The calculation for lifetime costs.

This calculation involves working out the lifetime energy costs for the LED bulb and adding these to the purchase figure. Then you then work out the energy costs for the general light bulb over the identical period of time and add on the price of 30 traditional light bulbs as the LED bulbs last 30 times longer.

LED Candle Light Bulb computation.

A cost of 15 pence for each kWhour of electricity used has been taken for these calculations.

The electricity cost for a 3 watt LED over a life span of 30000 hours is 13.50. The original purchase price is assumed to be 15. This adds up to a total cost over the lifetime of 28.50.

This LED candle light bulb will produce approximately the analogous lumens light output as a 25 watt traditional light bulb. A traditional bulb will have a lifetime of approximately1000 hours.

It costs 24 for 30 candle light bulbs at 80 pence for each individual bulb. To operate the candle light bulb for 30k hours costs 112.50. For 30000 hours this indicates that the traditional light bulb would have a total operating cost of 136.50.

Working this through you save an impressive 108 through the purchase of every individual LED candle bulb over its lifetime.

That is simply a most substantial cost saving achieved by migrating to LED bulbs.

MR16 LED comparison for a 3 watt lamp.

Working out the saving for the 3 watt MR16 uses a similar process so I shall not detail each and every step. It is crucial to differentiate between high powered varieties which retail at around 15 and the 48 LED variants which retail at around 10. The high powered LED's will have a single or triple beam whereas the 48 LED lamps have 48 different light beams.

Using the exact same cost data for the MR16's as we did for the candles the life span savings turn out as follows:-

A saving of 113 is attained through the use of the 48 LED MR16 for its lifetime.

You can easily save 108 through the use of the high powered MR16 LED over their life.

Again the savings are humongous and only vary by 4.5% across the different classifications of LED bulbs.
