) This
is a shield placed
over an old style unshielded
wall pack. The shield should be painted a light color on
the underside so
as to reflect more light down to the ground. Larger view |
by Cliff Haas -- This is an important
resource
for the do-it-your-selfer. The site provides a number of examples
of easy and inexpensive ideas to improve outdoor lighting. The example to the left is from See IDA Information Sheet 159 - Shielding Floodlights, by Bob Crelin |
) This
shield is placed over a wall
mounted flat lens shoe box.This wall is about 8 feet from the adjoining property. However it appear to be far more shielding than necessary. Larger view |

CAUTION --
Notes on Modification of
Light Fixtures --
1.a. Any modification which compromises the integrity of the fixture, such as drilling of holes etc. should be avoided. This invalidates the certification. 1.b. Modifications which would cause excess heat to build up in the fixture, such as fully enclosing a fixture in a box etc. should be avoided. 1.c. By compromising the UL approval, the modifier, property owner, and others may be liable if fixture failure causes a fire or other damage. 1.d. UL provides field certification of fixtures. For a large modification projects field certification may be a prudent approach. 2. Use manufacturers shielding. 2.a. Most manufactures provide shield for flood lights, house side shields or additional shielding for fixtures they manufacture. 3. Photometrics. 3.a. While it is the intent of a shield to modify the photometrics of a fixture, reduction of the light pattern in the intended target area should be avoided. 3.b. If it is shown that the intended light levels have been reduced below the jurisdictions minimum levels, liability may be an issue. 3.c. When ever possible paint the underside of shields white or silver, thus increasing light levels in the intended target area. 4. Legal Notice 4.a. Because of liability issues, International Dark-Sky Association does not support or condone modifications of light fixtures. 4.b. Information presented here and in our Information Sheets is for educational purposes only. 5. 5.a. Underwriters Laboratories Inc. (UL), is an independent, not-for-profit product safety testing and standards-writing organization. UL has been testing products for more than 110 years. 5.b. There are no laws specifying that a UL Mark must be used. However, in the U.S. there are many municipalities that have laws, codes or regulations which require a product to be tested by a nationally recognized testing laboratory before it can be sold in their area. 5.c. Many companies make it their policy to obtain UL Listing not only to minimize the possibility of local non-acceptance, but also as a matter of corporate policy and commitment to minimize the possibility of risk in the use of their products. 5.d. UL is concerned with the safety aspect of all potentially hazardous products. 5.e. UL primarily exists because of "liability issues" as is evident in 5.d. above. Please help us collect photographs and description or web links that show how various fixtures have been modified to reduce light pollution or light trespass. |
