I am looking to add some lights to the shrub bed against my house to provide ambient light to two very dark areas of my yard. My exterior doorway lights don't currently reach these areas and the lighting is now concentrated just at the doorways. I'm not interested in uplighting the house. I just would like to add about 4 or 5 area lights to fill-in these dark areas in the shrub beds along the foundation. There are no pathways in these dark areas, just shrubs and lawn. My home is a two-story colonial on a small 1/4-acre lot with narrow shrub beds that are about 4 - 5 feet deep against the foundation. What is the simplest way to select light fixtures and bulb wattages to light these areas to balance the intensity of the new fixtures with the current lighting? Is there a way to use a flashlight, work light, temporary spotlight or some other temporary lighting to mimic the desired intensity, then translate that brightness into the selection of fixtures and bulbs? I realize that there are professionals that have the equipment and software to accurately measure the existing ambient lighting and design a lighting system, but I'm just a DIY'er looking for an easy way to buy and install a few fixtures without making a big mistake. Thank you in advance!
