Oct: 14: Oxley, president of Outdoor Illumination, Inc., in Bethesda, presented an overview of outdoor lighting to enhance outdoor landscaping at night. While showing examples of the firms' work in the DC metro area, Oxley discussed uplighting and downlighting, forelighting and backlighting, avoiding glare and overkill. He said it was better to error on the side of less. In terms of equipment, Oxley urged members to opt for quality. He discussed the need for an outdoor transformer with an internal circuit breaker, 12 volt multi-reflector bulbs, wiring and an electrical source.
Following the meeting, Oxley led about two dozen members over to 6th and D SE to view the landscape lighting in a side garden which features what is believed to be the oldest winter-hardy crape myrtle in the United States.
Several varieties of crape myrtle grow in the United States. The common crape myrtle (Lagerstroemia indica) was introduced in the 1750s from mainland Asia. A Japanese variety (Lagerstroemia fauriei) was introduced in the 1950s and was used by the U.S. National Arboretum in the 1960s to develop a strain of winter hardy, disease resistant crape myrtles with decorative cinnamon--brown bark.
The tree on 6th street is apparently one of the earliest of these Lagerstroemia fauriei. It towers above the adjacent two-story row houses and is uplit. The transformer is below left:
