Alex,
One nice thing about using that adapter is that opens up the possibility of using Lithium batteries. The reason for this is that Lithium batteries are not susceptible to corroding your handle light. If that happens with regular batteries that you leave in too long, you may have to kiss goodbye your pricey handle light. I lost my long handle Mag flashlight that way, because in my move I wasn't paying attention to how long it had been.
I've had very few issues with batteries corroding, but i want to be especially careful with this one, as i'm sure it will become extinct one day. I want to keep this as long as possible.

I was even wondering, I wonder how hard it would be to fabricate this out of some other material (i'd never be able to since I don't know how to fabricate), but it's the thought that counts.
