Candles don t burn the same - meaning if a candle says up to 40 hours of burn time it doesn t mean it ll burn 40 hours no matter what It means it has the ABILITY to burn up to 40 depending on how you take care of it But luckily there s things you can do to make your candle last longer and reach that maximum time 1. Let your candle burn edge to edge every time you light it 2. Trim your wick - the larger the flame the faster it ll burn through your candle 3. Plan your candle time - I know this sounds crazy but what I mean is if you know it s gonna take 2 -3 hours for it to melt all the way across, plan to be available during that time
