Replacement of Halogen Spotlights by LED
Halogen spotlights are popular due to their high quality of lighting. However, although they are slightly more efficient than incandescent bulbs, they are still high-consumption bulbs.
Therefore, replacing halogen bulbs with LEDs is a significant energy-saving opportunity.
There are LED bulbs that can mimic the warm light of halogen bulbs with only a fraction of their electricity consumption.
Energy Consumption Comparison
Typically, a 60-watt incandescent bulb can be replaced with a 45-watt halogen, achieving 25% energy savings.
However, an equivalent LED bulb only consumes 10 watts:
- Energy saving is 83% compared to a conventional incandescent bulb.
- It saves 78% compared to the halogen bulb.
It is only necessary to verify that the LED bulb has a colour rendering index (CRI – Color Rendering Index) as high as possible. Both incandescent and halogen bulbs have a CRI of 100, the highest possible value, which means they mimic natural light sources like fire or the sun.
There are low-end LED products with poor CRI, sacrificing lighting quality for energy savings. Looking for an LED product with a CRI value of 90 or higher is recommended for best results. This way, lighting quality is not lost with halogen bulbs replaced with LED.
Shelf Life Comparison
In addition to offering significant energy savings, LED bulbs have a very long lifespan compared to incandescents and halogens.
- Conventional incandescent – 1000 hours on average.
- Halogen – 2000 hours average.
- LED – 25,000 hours for a light bulb, 50,000 to 100,000 hours for commercial or industrial fixtures.
Therefore, LED bulbs save energy and you from buying many replacements and trips to the hardware store over their lifetime. An LED bulb is more expensive than a halogen bulb, but compared to the 12 halogen bulbs it replaces over its lifetime, it’s cheaper.
In addition to offering greater efficiency, LED bulbs have a longer lifespan than halogen bulbs.
Replacing halogen bulbs with LED offers significant savings in energy and bulb replacement, but it is necessary to ensure that it is a quality LED product.
First, a CRI index as high as possible should be sought, preferably greater than 90. It is also recommended to look for the UL (Underwriters Laboratories) seal on North American products and the CE (Conformité Européenne) seal on European products.
