Harry999, please report back on your new Neutron. Mine new one had a different reflector than my older Neutron which made the previously great flood beam horrible in the new model. I also had the "moonlight mode bug" in this new 1A cool tinted Neutron and it had a wobbly head. 3 strikes and your out. I'll never order another one. (see my thread link in my post above to see the the new Neutron reflector).

Just to confirm the Neutron 2AA Cool I received today was old stock and has that beautiful flood beam with a pure white tint. I am very happy with it. It goes into storage just in case anything happens to my other four...
By the way I mentioned the buggy UI with the Neutral version of the Neutron to my local supplier. He commented that I should try to clean the threads and contacts in case some non conductive lube had seeped into the circuit. I used Isopropyl Alcohol followed by Deoxit and the some Nyogel. This has significantly decreased the frequency of the moonlight mode disappearing when you loosen the head. It gives me hope the UI quality will improve with time.
