P.S. - The RAB Electric Manufacturing, Inc. Model: WP1C Series looks particularly interesting. It has an adjustable shield - a nice feature I have not seen before. http://www.darksky.org/fixtures/wallutil.html Personally, I just use security lights with built-in daylight/infra-red sensors. These IR detecting security lights are always in "zero-light pollution" mode unless there is someone on the doorstep, although they look ugly for a front-porch application. Such security lights cost about $25 each on sale, when I bought them about six years ago. IR detecting security lights are a nuisance when trying to observe from your front porch. The security lights can be forced into zero-light-pollution "off" mode, when setting up a small refractor for a few minutes of relaxing post-work lunar viewing, by directing a red pointing laser into the light's daylight detector. The security light's daytime sensor is triggerd by pointing the red laser into the daylight detector-switch. Rubber-band a laser red construction level ($19 at K-Mart/Smiths) to a camera tripod. The red-laser construction levels have the convenient feature of a positive on/off switch. Ordinary red laser pointers with a push-button spring-loaded switch can be rubber-banded to a camera tripod and held in "on" mode with an $2 spring clamp (available at K-Mart/Smiths or any hardware store). - Canopus56 __________________________________________________ Do You Yahoo!?
