There was a huge debate on this before they look them off the market. People are still outrages. I bought 48 40watt bulbs before they sold out but I missed all the bigger. I got them on Amazon and when I tried to buy another box of 24 the price was tripled.
I did not know incandescent lights are off the market in the USA. I thought they just stopped production of 100Watt.
I am using 37w 110v flood lights on an AVR in my brooders at night as an experiment to see if they last longer.
I think I can drop to 25 watts
