Benefits of LED

There are several benefits attributed to LED lighting compared to more conventional incandescent bulbs and fluorescent lighting:

Long Life: 65x Longer than Incandescent, 10x Longer than Fluorescent
Energy Efficiency: 80-90% More Efficient Than Incandescent and Halogen Lighting
Low Voltage and Current Requirements: Generating Significant Financial Savings
Ecologically Friendly
Direct Lighting/No Wasted Light
No UV Emittance: Will Not Degrade/Damage Sensitive Materials or Fade Paints Under Illumination Area
Durable: No Moving Parts, Can Withstand Vibrations and Impact
Minimal Maintenance Requirements: Replace Lamp Every 50,000 to 100,000 hours
Security: No Lamp Failures, No Dark Spots
Safety: Instantaneous, Constant, Direct Light Over High Risk Areas i.e. Workshops, Stairwells etc.

On the left hand side of the image above, you can see the new LED light fixtures, and on the right hand side, we have the old fluorescent fittings. Both areas showed similar and sufficient illumination when accurately measured with lighting equipment, however, looking at the ceiling of the building we can see the difference in 'lost' light between the two methods. The LEDs have minimal light escaping onto the ceiling due to their direct and focused nature, whereas some of the fluorescent light has been 'lost' onto the ceiling which results in energy being wasted.

Example for Comparison

The table below gives an example of the total running cost of LED Lights compared to the more traditional incandescent or CFL option:
