LEDs and electricity savings

[sphelps]

Could be people using a variable electricity rate, which I had last year and it changed from $0.06 to $0.14 throughout the year. Otherwise could be those using chillers at certain times of the year or a number of other reasons relating to equipment changes and tank demands but nothing that shouldn't be fairly obvious to the user.

Yes savings for me works out to around $10-$13 per month.
