Recently came into some Eiger stuff in a trade. Ended up with an older single mode AAA body with a very warm white led. Also got a 10180 body only. I now have 2 new heads coming; one mule and one regular both high CRI. Noticed in the bottom of the 10180 tube is a small black donut that looks like rubber. I am assuming that it is QTC material. My question is, will these new heads fit the 10180 tube. I thought I remember reading that these were standalone lights and not interchangeable.
Hoping I am wrong.
