[Rhodes22-list] Environment

[Joseph Hadzima]

The ones I use out side the house are fine, except for cold
weather ... then they require a while to fully illuminate
... They start slowly, and are dim, and slowly gt brighter.
 But they seem to last longer, and I switch many moons ago
to reduce energy usage around the house.  I was just
curious about any waste management issues.

happy conservation!
