NEW OLD STOCK, NEW IN BOX WITH CLIPS

LOT OF 4 (four) OHMITE 500 ohm 225 WATTS VITREOUS ENAMELED RESISTORS.  Stock# 0907

It states on all four boxes, "formerly 200 watts"  I don't know what that means.  I am not a Engineer and have very limited knowledge of resistors.  If I have made a mistake please feel free to correct me.  Thank you for looking at my listing!
