So I am attempting to engrave on the ceramic tile which I am making progress but that’s not the only purpose for this topic I have a question. My laser is an atom stack p7 M30 and my dad is concerned about the electrical bill with laser usage especially with tile as well as with regular use now I might be wrong and please correct me if I am but on one tile project it requires 5 hrs to complete that’s where my dad’s concern comes in will that raise the electricity bill or will there be not much chang to the bill…. OR am I not setting up the correct settings for said project ? My location is in Oklahoma and my laser is 5 watt diode I did try to contact the electric company and they couldn’t tell me any information

      The website for this product specifies the 5.5 W output of the laser and also lists a 30 W electrical output, but it’s almost certainly referencing the power consumption or 30 Watts. Electricity is measured by kiloWatt hours and charged in the same manner. The rates local to us have recently been raised to US$0.14 per kWh. Yes, fourteen cents per kiloWatt hour.
Let’s kick the number up a bit to twenty cents per kWh. The k is one thousand, which means you’d have to run the laser for 1000 / 30 or about 33 hours to use one kWh, or twenty cents.
