Hi, I used the current calculator that is on this site but I found out it goes to the max mercury content per bulb instead of the average of the building. 

So I have three options:

the total mercury content per bulb multiplied by the quantity of the bulbs / total number of lamps purchased 

or 

only the total mercury content per bulb / total number of lamps purchased 

If I do any of this, my building does comply with the requirements of less than 70. 

If I stick to the max number, which is 108, my building does not comply with the requirements. So which number should I use?
