The crazy thing is you can still buy a 100-watt light bulb for about 25 cents in today’s dollars.
Why take chances with eyes?
Good light costs so little
Eyesight is priceless . . . good light is cheap. Why take unnecessary risks? You can buy a genuine 100-watt Edison Mazda lamp, the size that is so fine for reading, writing or working, for only 25 cents, and the smaller sizes, 75-watts and under, for only 20 cents. These good lamps not only help guard against eyestrain… they protect your pocketbook by using electricity economically. And they don’t burn out too soon. Why take chances? Look for this mark on every bulb you buy.
