The main cost when running lighting is the electricity to power it - so the less electricity used then naturally the better the financial benefits.
Halogen and incandescent light bulbs are the cheapest lights to buy. However they are also the most expensive to run. This is because 90% of the energy is wasted on heat and only 10% is actually converted to light. This meaning that you can never expect a positive cash flow when using these types of light bulbs. The high amount of electricity they use for their output will always be an expensive method of lighting.
LED's on the other hand use very little electricity. They waste only10% of energy and use 90% of the energy as useful light. This making LED lighting very cheap to run as they use so little energy. The initial cost maybe higher but depending on how little or often you use the LED lighting you can expect to recoup your costs in no time at all.
The other major financial factor to consider is life expectancy. (the cost of replacing a bulb over a given period of time). If you use filament bulbs then average life expectancy is 1000 hours. This meaning that you will probably be changing these quite often , although the cost to replace is not that high, over a 10 year period this will add up.
LED tape has a life expectancy of between 50,000 to 70,000 hours. In real terms that equates to around over 20 years, meaning replacing the LED tape is virtually irrelevant.
LED tape is not made out of glass or tubes meaning they are less prone to accidental dame - LED tape is effectively a fit and forget product. The LED tape can also be waterproof meaning that any water damage, steam etc. will not fault the product.
LED technology is so advanced and the cost to but the LED's has dramatically been reduced making them available for the mainstream market. LED technology is advancing more and more at a rapid rate so the predicted future costs are to be halved within the next 5 years making the product more and more financially beneficial compared to comparison alternatives. The futures bright....the futures LED.
