The LEDs are already knocking on the door. Pretty powerful and soon available at the right warmth and brightness.
i also think the same
LED is the future.
i am not sure about just one thing - how much energy factory needs for making amount of leds equal to one "old fashioned" bulb?
similar debate was about toyota Prius - how really that car is "greener" then ordinary one - if we include energy needed for making it from basic elements.[ Parent ]
they also did not figure in repairs as the prius is reported (by toyota) be in the very low cattagory for problems/repairs, I do not know about the hummer.
As for lifespan it is reported some of the early prius's are getting up on the high miles of over 200000 miles with the origanal batteries
just do a search for "prius hummer" and you will find alotg reif [ Parent ]
