What You Can Do

Fortunately, commensense lighting design and modest retrofitting solve most of the problems under control of residents and business owners/managers. It has been said that light pollution is the easiest and cheapest pollution to control.

Residents

  • Direct outdoor lights down, not up, and retrofit with shielding.
  • Use motion detectors on security floodlights or retrofit with shielding.
  • Use low wattage for landscape lighting and, when possible, direct the lighting down, not up.
  • Use timers to turn off landscape and string lighting after 10pm.
  • Use efficient light sources for outdoor lighting around homes and agricultural buildings. Consider a compact fluorescent for good, energy efficient, economical lighting (a low-wattage lamp gives plenty of light for most properties and applications, and in a fully shielded fixture, it makes an excellent choice.) When higher wattage lamps are necessary, be sure that they are fully shielded, energy efficient, and with 3,000 or less Kelvin so that blue spectrum illumination is avoided. (IDA Guidance)
  • Talk with neighbors about the inexpensive ways they can replace inappropriate and unshielded lighting with more effective fixtures affording greater security.

Business Owners/Managers/HOAs

Consider signage

  • Does it conform fully to requirements of the Ogden Valley dark skyLighting and Sign Ordinances?
  • Has its cost been amortized at least ten years?
  • Is it internally lit? [If so, it should be changed to externally, downward directed illumination or redesigned for size and dark opaque background (see photos, right).]
  • Is there a clear design aesthetic that reflects, in some way, the scenic beauty of its surroundings?

Evaluate lighting

  • Use efficient light sources for outdoor lighting around businesses. Consider a compact fluorescent for good, energy efficient, economical lighting—a low- wattage lamp gives plenty of light for most properties and applications, and in a fully shielded fixture, it makes an excellent choice. When higher wattage lamps are necessary, be sure that they are fully shielded and energy efficient. (IDA Guidance)
  • Eliminate or turn off string lighting by 10pm (recommended by current Ogden Valley Lighting Ordinance)
