I recently lost one of these four lamps. I was going to replace them all with LEDs but every review said the light box cap wouldn't fit since the bulb is basically 1/4-1/2 inch longer. The photos confirmed this. So no LED replacement, but I still wanted to replace the bulb! I don't use them often, but one of the four that didn't bothered me. I bought this product and it is dead for the same size. It gives off a bit more of a white glow, but honestly you won't notice it unless you stare slowly at all four. Can't comment on durability but bought a six pack just in case. How it helps! Again - check the dimensions of the replacement LEDs. If you have a small glass and metal lid that attaches to the light figure, other options may not work. The main thing is that everything fits!
