LED Bulbs
Facts about Lighting
- Electric lighting burns up to 25% of the average home energy budget.
- The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself.
- Red and Green lighting are ideal for maintaining night vision
- Amber lighting doesn't attract insects and is ideal for outdoor party/barbeque lighting
- Blue Lighting is excellent to read by and many people have reported that they can read for much longer under blue light than by conventional multi-spectral light.
- Warm white light is ideal for home and mood lighting
- Cool light is better for task oriented lighting where detail and precision is desirable.
LED Spotlights & Downlights
- Equal or superior lighting to existing incandescent or halogen lighting
- Doesn't protrude beyond your existing housing
- Cut your electricity bill by 90%
- Typically pay for themselves in under 18 months
- If you consider LED lighting in terms of an investment, then every Euro invested in LED lighting will pay for itself fifteen times over in recouped electricity and hardware costs 15 times over its lifetime compared to the alternative. That's a 1500% return over the lifetime of the bulb or 88% annual return !
Savings per bulb assuming 6 hrs usage/day. LED vs Halogen 50W downlight
- Year 1 : €4.77
- Year 2 : €34.54
- Year 3 : €64.30
- Year 5 : €123.84
- Year 10: €279.68
- Year 20: €591.36
- LED lighting...the future of lighting
- Ultra efficient. 3 watt LED is the equivalent of a 50 Watt halogen (Only 6% of the power!)
- Won't overheat or smell
- Up to 25 years service (you may never change this bulb again!)
- Instant brightness, no "warm up" time like CFL bulbs
- No flicker or hum
- Long-lasting - LED bulbs last up to 10 times as long as compact fluorescents, and 50 times longer than incandescents.
- Durable - since LEDs do not have a filament, they are not damaged under circumstances when a regular incandescent bulb would be broken. Because they are solid, LED bulbs hold up well to jarring and bumping.
- Cool - these bulbs do not cause heat build-up; LEDs produce 3.4 btu's/hour, compared to 85 for incandescent bulbs.
- Mercury-free - no mercury is used in the manufacturing of LEDs.
- Lower Maintenance costs - Because these bulbs last for years, energy is saved in maintenance and replacement costs. For example, many cities in the US are replacing their incandescent traffic lights with LED arrays because the electricity costs can be reduced by 80% or more.
- Cost-effective - although LEDs are expensive, the cost is recouped over time and in battery savings. For the AC bulbs and large cluster arrays, the best value comes from commercial use where maintenance and replacement costs are expensive.
- Light for remote areas - because of the low power requirement for LEDs, using solar panels becomes more practical and less expensive than running an electric line or using a generator for lighting.
Trade/Industry Applications
- Long life makes LED technology is ideal for hard to reach locations where the labour cost of replacement is significant
- Low running costs make LED lighting ideal for cost effective display lighting
- Narrow light frequency emissions won't cause display items to fade
- "Cold White" LED lighting is superior for detail lighting of small objects
- The absence of IR radiation allows LED fixtures to be positioned in locations where heating from conventional sources would cause a particular problem e.g. illuminating food or textiles
