[Vision2020] Outdoor lights

[Jeff Harkins]

Great post Fiat:

I too use the motion detector system - a perfect solution for my wife and I 
- it is not clear that that would pass mustard with the ordinance - it 
requires photo sensitive.

Looks like a perfect opportunity to "enlighten" lots of folks on the 
issue.  When informed about light and all its elements, folks can make 
rational choices about what light they need.  I am confident most would opt 
for the "best" solution for their needs.  Thanks for getting that thread 
started.

And it is certainly a process of education.  One poster noted that the use 
of the Energy Saving Soft White Light Bulb is so much better than the 
incandescent bulb.  But of course, the Energy Saving bulb is an 
incandescent bulb - it simply uses a different filament material.

On the Sylvania line of bulbs, here is their recommendation for choosing a 
light bulb:

"To save energy costs, find the bulbs with the light output you need, then 
choose the one with the lowest watts"

Another point noted on a box of GE Miser Floodlights (their energy saving 
line of products) is:

"The Miser Floodlight has a shape designed to gather stray light that 
standard floodlights waste and redirect that light back into the useable 
beam"

Of interest again, this is an incandescent light.

Finally, GE includes this tip on the energy saving issue:

"For greater energy savings use GE Halogen Floodlights"

Of course, horse owners and other barn keepers know that halogen lights are 
a no-no for barn use because of the heat they generate.

Finally, glad we got some discussion going - and your post helps.
