Drano, I love my MR BUDDY propane heater. One room or more size is about $70 on Amazon. Comes ready to use the little 1 lb bottles for $2 or $3 each. You can also get a hose to hook it to a 25 lb tank. Read the instructions. leave a window open a bit for safety, and have a carbon monoxide detector that works. Should have one any how. I think it also has a built in low oxygen detector. I have only used it for about 45 minutes since the weather has stayed good since I bought it - figures.
Also, I have a couple little grills that use the same bottles. When we were out of power in Puget Sound area a few years ago, I cooked all sorts of stuff on the grill in stainless steel cake trays: coffee, french toast, scrambled eggs, soup etc. in addition to all the usual grill foods.
I'm with you on led lights. I found that that the most useful were the LED headlamps. Got a 3 pack at Costco for about 10 bucks.
