Incandescent vs. Halogen vs. LED Landscape Lighting
Below is a chart/illustration of the vast difference in energy costs for the different types of lighting. I’m passionate about the new LED on the market and I’m always encouraging my clients to make the change. In a previous post, I discussed how one client in particular made the change from halogen low voltage landscape lighting to L.E.D. landscape lighting reducing his energy usage by 88%.
I put together this chart to illustrate how the simple change made such a powerful impact. To keep it simple, the quantity for each type of light is equal to one (for example, one 60 watt incandescent will cost $12.23 per year). The calculations are based on a landscape lighting system running for 7 days a week, 4 hours a day and paying .14 kWh (this is for illustration purposes and not intended to confirm exact costs).
| ***Illustrates the vast difference in energy cost savings | |||
| Bulb Type | Incandescent | Halogen | LED |
| Bulb Wattage | 60 | 20 | 3 |
| Qty | 1 | 1 | 1 |
| Avg Hours/wk (4 hours/night) | 28 | 28 | 28 |
| kWh/Year 1000 | 87 | 29 | 4 |
| Dollars / Yr .14 | $12.23 | $4.08 | $0.61 |
This snapshot is a good indication of how the energy industry is becoming more efficient. These numbers become even more significant when you up the quantity (run 10 incandescent @ 60 watts each and pay $122 per year).
As always, my goal is to present quality information in a non-technical format. Hope this helps.
Take care,
