Replacing incandescent automotive lighting bulbs with LED ones
Its "OT" to discuss the TeaBagger's flap on the NRDC's effort to
drop 100 year old lighting technology for more efficient ones
(please do-not do that here).
My topic is EV-related about use of more efficient automotive lighting.
>From what I have read, NRDC's efforts are focusing on non-automotive
lighting (at this time) in an effort to reduce power plant
electricity waste.
I sense it goes beyond the "Well good, that's more electricity for us
EV'rs" initial feeling one might have, to at some point, automotive
lighting will need to be upgraded to the 21st century. While we do
not have to do anything right now, some questions come to mind that
might be interesting to ponder:
-How much power is incandescent EV lighting using?
(head lamps, turn signals, back up lights, dome, and gauge cluster
back-lighting, etc.)
-Where does one go to explore non-incandescent automotive lighting?
(Online, Auto-stores, ???)
-Who has the best prices?
(Got URL?)
-What is the life span of an automotive LED light?
(Write them in your will for the great-grandkids?)
-How much would be saved by switching to LED lighting?
(Pennies, Dollars, Sense?)
-How far would switching go to show how serious EV drivers are
about conserving resources?
(She's even using LEDs to save power ... )
-What is the cost analysis of staying incandescent to getting
with the program?
(Are you part of the problem, or the solution?)
In the excerpt of the NRDC page below, it states how higher wattage
LED lights have to be designed to dissipate the heat from the base,
and diffuse the light emission radiation to be comparable to using
incandescent lighting.

Are today's LED bulbs ready to work as substitutes for
incandescents?

to avoid overheating.
They are a good choice for many applications, but not yet for screw-
based sockets because of the way they give off heat. Where
incandescent bulbs radiate heat from the glass, LEDs radiate heat
from their bases, where it's more difficult to dissipate. This can
impair their efficiency.
Another problem that LED makers are working with is that because of
the way LEDs make light -- in narrow beams -- current LEDs are best
suited as directional light sources. For omni-directional coverage,
when you need to light a whole room, current LEDs might not be best.
But in some uses, they're a good fit, such as for recessed ceiling
lights ...
