[RE-wrenches] 110Vac LED resistance to weak grids in developing world

[toddcory at finestplanet.com]

i have some personal experience with led light bulbs. i put them outside because the cfl floodlights are very s-l-o-w to warm up to full brightness.
 
1) leds are still slightly less efficient (lumens per watt) than cfl's
2) led light bulbs (2 different brands) throw out an ungodly amount of rfi... want to listen to a conversation on the 2 meter ham radio or listen to a weak fm broadcast station or watch channel 6 on the tee-vee? go shut off the led lights off first.
 
my conclusion? led light bulbs are not ready for prime time.

Hello wrenches
 
I am in Central America and looking to suggest customers buy efficient LEDs for illumination in their 120V-wired homes, connected to local power grids with less-than-desirable power quality.
 
I see that so many manus claim long life for the LEDs, in the tens of thousands of hours, yet so few if any back it up with a decent warranty.
 
Folks are hesitant to make this investment, believing that voltage surges or dips could destroy the LEDs.
 
Has anyone heard of LED lights' lives ending prematurely due to grid events? 
Would inline surge protectors [something small to be installed immediately downstream of the breaker in the home's main panel) be helpful, and if so, does anyone have any recommended brands?
 
thanks
Jim MacDonald
