Letter Re: 12VDC LED Christmas Lights for Emergency Lighting

Jim:
On a lark, I order two strings of these 12 VDC LED sort-of Christmas lights. I ordered one string of blue for the porch (really easy on Night Adapted Eyes and one string of white.
Wow! Really neat. Low current (i.e.: extremely low power consumption) and just plain handy. I’m just guessing but I figure two strings would run for 6 weeks on a fully charged car battery.
Nice for those “loss of electricity days/nights” and a lot cheaper than the camping/emergency lighting systems. I think it is a reasonable purchase.Best Regards, – The Army Aviator
