Many homeowners avoid installing outdoor lighting because they think it will increase their utility bill costs. This could be true if you use standard bulbs, but the increase in cost is relatively low when you use LED bulbs. We use energy-efficient lights that consume low energy, and landscaping of 20 lights would consume under 18 kilowatts of electricity per month, which will cost around $5 a month. It's a relatively low price to pay, especially when you consider how beautiful your landscape will be and how your house will be safer.
