Is it possible to modify the E2 bulb assembly to make it fit the scorpion? The two look similar to me. Even if the assembly don't work on the scorpion, can the bulb be removed and use as a bi-pin? I've heard that the E2 bulb last longer so it would be nice if I can use that on my scorpion. The bulb on my scorpion is blackening and it's only on its second set of battery.
