    Replied to all PMs.

    BTW the number of PMs received so far happens to equal to the number of packages I bought the other day, so I will be able to ship them all simultaneously, hopefully later this week. And buy more packets for the next wave of shipments if there are more confirmations.

    In a matter of fact, the 5mm LEDs are now out of stock, all versions.

    Please accept my apologies, but unfortunately I will need to decline at this point - PM sent.

    This should free up 10 emitters, and I do hope that others here may be able to find a use for these, so that you are not inconvenienced.

    Thanks for your understanding.

    My deepest apologies for holding up the process- I had mis-spelled ma tumba's Paypal address... Sorry everyone!

    All paid ones shipped out this morning. I will supply tracking numbers via PMs later today, but I don't expect them to appear in USPS tracking system before Monday.

    I didn't receive tracking, just want to double check it shipped.

    Everything shipped out Thursday, all tracking numbers provided this morning. Wanted to provide them earlier but CPF was so slow to me that I just gave up at that time.

    I checked the US bound shipments, thay are all available in USPS tracking system already. The other shipments are available in my local system so I am sure they are on track, too.

    I noted your request. It is pending confirmations of other members that subscribed earlier. I think the deadline for them would be July 1st.

    For folks that have received theirs, if anybody wants to know of a 1xAAA host, I found out the Sunwayman R01A is unpotted and I was able to solder one in. It was tricky due to the small size, but patience and modest soldering skills are enough to do the swap. I have pictures of how the pill comes apart if needed.

    The R01A doesn't seem to be quite as durable or efficient as the Fenix E01, but it is small and well-regulated.

    The 5mm LED fits a TAD's e-series socket. Easily focused in an e1 bezel, providing very nice beam. ZERO tint shift.

    One interesting observation though. When powered by a 3V cr123, the cct is about the nominal value of 3200. But when powered by a 3.7V rcr123, the cct shifts to much higher temperature, providing a gorgeous ~4000K light. So kind of nice overdrive in the LED world.

    Excellent looking tint lucky. How is the brightness compared to original on the r01a?

    If any of these LED's gets freed up by any on the list who have changed their mind, please put me down for both 3200k and 5600k versions.

    Similar ballpark, but obviously more flood, less throw. I'd have dig through my notes to be sure, but I think I was careful to use exactly the same settings for each photo, so it should be a good comparison.

    I measured current at the LED as 23 mA. The Yuji is rated 6-8 lumens at 20 mA, so it should be right around there. It might actually be a bit more, because with low currents like this, the internal resistance of the ammeter can unintentionally reduce the current.

    There were more modding ideas in this thread. Coin cell lights are a popular and easy one. Leanburn found these LED's also seem to survive just fine direct driven on 2 alkaline batteries - not even using a resistor. That also sounded very easy as a replacement for a bi-pin bulb, such as a Maglite. I think at least one person put one in a Gerber Infinity Ultra, which is probably overdriven.

    Wow! 3.7V is a lot to put into such an easily-driven LED as this. I can only imagine it significantly reduces the life of the LED, but it's great that it seems to be working so far. The thought of a Yuji is a Surefire is awesome!

    I would like to see pics of the pill removal on the r01a if you get a chance. I may pick one up if the soldering isn't to delicate.
