Sold/Expired (2 CLOSED) D26 Copper 1x26650 Host From FIVEMEGA

I was using NB's XML drop in at 3.1 amps. I left it on for over 2 minutes though. I would guess closer to 15-20 minutes.

I've left NB's SST50 @ 2.8 amps on for awhile in the older model and it got quite hot, but the tail cap never got as hot as the copper version's. I'm not sure how much difference 0.3 amps makes, but I was quite surprised to get burned by the tail cap.

The new copper D26 host is 34.89mm wide at the widest part of the body and the older non copper version is 31.76mm wide at the widest part of the body. The copper host weighs 5.40oz and the non copper version weighs 3.15oz. These weights are the body and tail cap only.

The first three pictures are of the new copper host and the last two are of the older non copper version. All 5 pictures have a LF mini-turbo D36 head that was coated in HA III black.

Thanks for the replies guys. I appreciate it.

QtrHorse,
I just saw post #27 of this thread which definitely shows that the copper host is a lot thicker than the previous non-copper host. The tailcaps are switched in the photo but other than that, the diameter differences of the copper vs. non-copper host is significant.

But I will wait for your measurements. Thanks for your input which will help me decide some things when FM does a second run.

swrdply400mrelay,
What type of drop-in are you running to get the tailcap hot after 2 minutes? Or does the hot tailcap show that the clicky is being pushed to the max in regards to current flow through it? In any case, your experience seems to suggest that the copper insert works as advertised. Impressive.

QtrHorse,
Thank you very much for all the work you did for me. The pictures are great! The older model fits the LF head perfectly.

The pictures really show the difference in the fit up, especially with the increase in diameter of the battery tube. On that point, the diameter is getting too big for me because I still want to hold it cigar-style and I have small-medium hands. I understand the increase in diameter is due to the copper insert, not to mention the extra mass for heat sinking.

As for your measurements, they show that the battery tube diameter is almost the same as the tailcap diameter. That is one massive, yet compact light. I wouldn't mind if fivemega's next run was made a bit slimmer for better ergonomics but I'm sure the main crowd probably prefers more heat sink mass.

My perfect light would be a slimmer battery tube like the previous non-copper version and a mini-version of FM's turbo C head.

Once again, I really appreciate all you did for me. A big thank you! carl

swrdply400mrelay,

OK, 15-20 minutes makes sense. If the outside is "hot", the drop-in must be absolutely white-hot! But in any case, the copper must be doing its job. Thanks.
