If you only intended to live two or three more years, your analysis would be perfect.
You are comparing a bulb with a higher initial cost and a far longer life to a bulb that has a lower initial cost and a shorter life. Your comparison is over a shorter life.
Bad comparison.
By the way, I am getting LED bulbs for around $5.
