I don't even remember which comment of mine you're replying to at this point lol.
If it's the one where I was asking about the HLG light, then...my tent currently runs at 15w per sq ft and barely budges my electric bill. Doubling what I draw from then wall will only add $14 to the bill.
If it's the one about the sound activated bumbershoot, All you have to do is replace the battery and yell "Gardyloo" into the horn at the top, The gubbins should reset and you're good to go.
