Recent advances in Light Emitting Diode (LED) technology have lead to LED bulbs overtaking Compact Fluorescent Lamps (CFL) as the preferred low energy alternative to halogen. As well as lasting thirty to forty times longer than halogen and three to four times longer than CFL, LED bulbs offer far greater energy savings. In terms of light output, LED bulbs now provide the same quality and intensity of halogen.

LED Bulbs are Easier

to Replace than Low

Voltage Bulbs

Recent advances in Light Emitting Diode (LED) technology have lead to LED bulbs

overtaking Compact Fluorescent Lamps (CFL) as the preferred low energy

alternative to halogen. As well as lasting thirty to forty times longer than halogen

and three to four times longer than CFL, LED bulbs offer far greater energy

savings. In terms of light output, LED bulbs now provide the same quality and

intensity of halogen.

Earlier generations of LED bulbs gave LED lighting a bad name within the lighting

industry as they provided very low levels of light and produced poor colour

reproduction. Older generations can generally be identified by having a bubbly

front lens with multiple LEDs whilst new power LEDs are flat and contain three or

four power LEDs behind a glass front, similar to a halogen. More advanced LED

chips are now used from manufacturers such as CREE that produce the same clear

white light often associated with halogen. Older inferior LEDs should only be used

for decorative purposes not ambient lighting. High power LEDs now offer a true

low energy lighting solution.

The main problem with LED bulbs is the price; they cost around ten times more

than halogen and three times more than CFL. This price is justified when you

consider savings that can be made.

The first saving is made in the life expectancy of the bulb; you're actually getting

better value for money by choosing LED. For example a fifty watt halogen bulb

will last for two thousand hours, compare this with a seven watt Philips Master

LED bulb which will last for forty thousand hours. This means that over the same


Led bulbs are easier to replace than low voltage bulbs

time period of forty thousand hours you would be paying for twenty halogen

bulbs when just one LED bulb would do. This would make a saving of around ten

pounds as buying one seven watt Philips Master LED is cheaper than buying

twenty fifty watt halogens. Admittedly this saving could take long period of time

to achieve and will depend on how many hours per day the bulb is in use.

The forty thousand hours life expectancy of the Philips Master LED could range

from four and a half years (if left on constantly) to over eighteen years (if used for

six hours a day). The best way to convert life expectancy into actual days or years

is to base the daily usage by the hours per day it will be left on for. For example; if

the LED is used for six hours per day, it will last for eighteen years. If the daily

usage is less than six hours it would last even longer. LED bulbs are a fit and forget

product.
