2xAA Eneloop should run about 8-9 hours with a M31LL 219b. 2xAA Energizer lithium would be around 12 hours. 1xCR123 should be about 4 hours.
This setup is what I store in my vehicles along with CR123 and AA e2 lithium cells. They're in hosts that are convertible from "3p" to "9p" with delrin sleeves and a dummy 1xAA cell in case I want to run them on a single AA in a pinch.
What value resistor are you using on your modified high/low ring, and what would you estimate the output to be on low?
Anyone know if illumn is going to get MDC AA 219's back in-stock?
Hi, I just purchased one of these to drop in to my MD2 head. The head wrench has been oos for a while now and I've had this drop in for weeks with no way to switch it out. I have given up on waiting for a restock of the head wrench, is there a certain size and/or model number of circlip pliers I can use to remove the hi/lo ring?
