CandleLifeEmergency Survival Candle (Set of 4) - 115 Hours Long Lasting Burning Time - Great Source of Light for Blackout, Camping, Fishing and Hunting - Smoke & Odor-Free | Clear Mist

Good to have an emergency backup.

Actually burned longer

Geez.... it is an emergency candle. Says so in the name! No emergency yet. Check back after an emergency and the lights go out.....hahahaha

Adequate illumination; no tell-tale scent; no smoke.Recommended.

I used this in the small un-insulated shed housing the wellhead for my water well when we had temps drop into the low 20's.The first day, I checked a few hours later and it was out and the fuel was gelled. As in other reviews, the wick comes very short. So when you pull the stopper on the wick, get out your multi-tool pliers and carefully grab the wick and pull it out another 1/4". Did that and it's still burning 4 days later.I put this inside a clay planting pot, with another, smaller one inverted over the top. Air still gets in through the drain hole on the pots, but it blocks the wind and also traps the heat so the fuel doesn't jell. It also then radiates that heat into the space. This is a trick I picked up from that "Creek" guy on the Fat Guys In The Woods survival show, who wrote a book on survival tips. Works well. If the temps continue to drop, you can put two or even more of these together. Each one bought me ~4-5 degrees. In a better insulated space or with less draft, the heat would stay in the space better.
