The cutting-edge technology of LED bulbs means that they save a appreciable amount of electricity, on the other hand, their price can be considered to be quite astronomical! The extra benefit is the astonishingly long life so all in all are they worth investing in? The bestmost way to get factual data of the financials is to analyse the lifetime costs for LED Bulbs and compare this to standard light bulbs.
Total cost of ownership assessment.
This calculation involves working out the lifetime energy costs for the LED bulb and adding these to the purchase price. Then you then work out the energy costs for the common light bulb over the identical period of time and add on the price of 30 everyday light bulbs as the LED bulbs last 30 times as long.
LED Candle Light Bulb calculation.
A cost of 15 pence for each kWhour of electricity used has been taken for these calculations.
The cost of a 3 watt LED candle is about £15. The electricity expenses over the lifetime of the LED bulb works out at £13.50. This leaves a total lifetime associated cost of £28.50.
A 3 watt LED candle will provide the same lumens light level output as a 25 watt traditional bulb. A normal bulb will have a lifetime of approx.1000 hours.
It costs £24 for 30 candle light bulbs at £0.80 for each individual unit. To run 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.
The outcome is a saving of a massive £108 by the purchase of the 3w LED candle bulb over the lifetime of the bulb. This means that through the purchase of the LED candle bulb a huge saving of £108 is accrued over it’s lifespan.
This is truly a massive cost saving accrued by using LED bulbs.
MR16 LED comparison for a 3 watt lamp.
The arithmetic for the 3 watt MR16 uses an identical logic so I will not go through every single step. As the logic for the evaluation for the 3 watt MR16 is the same I will not detail the full calculation. The crucial choice here is that the MR16 LED’s can be acquired either as a 48 LED lamp or with high power LED’s. Here we need to accommodate for the difference in purchase expenditure with the 48 LED version costing mostly £10 and the high power version costing most often £15. The high powered LED’s will have a single or triple beam whereas the 48 LED lamps have 48 different light beams.
The price of the MR16′s is taken to be £0.80 as with the candles which means that the life savings are;
£113 is saved by changing to the 48LED MR16 over its life.
You are likely to save £108 through the use of the high powered MR16 LED over their life.
As I am sure you will agree these savings are truly astounding and do not change much with the multiple LED or high powered LED bulbs.
