NOTE: Please read edits and updates at the bottom of this post for changes and additions to the offering. Thanks!
Hi guys,
This is a small wave (8 lights) of the titanium SunDrop XR-U discussed in greater detail, HERE. The light consists of a 3S converter driving a Nichia High CRI 083B LED. The XR-U head has the same sapphire lens as that of the original SunDrop but the lens is positioned further from the LED. In the case of the Nichia LE, this means a tighter flood angle and higher lux.
The 3S converter provides ~330 mA to the Nichia 083B High CRI LED. Medium and low levels are PWM with reduced duty cycles of this set current driving the LED and resulting in lower output. The designer of the converter has tagged the converter as a "constant color" driver.
This head is also compatible with any number of other Aleph style light engines as well as the Cree 3S LE I have been using in the Haiku lights.
I have called this small wave because I hope to continue to use this thread and offering for subsequent waves of these lights. I may have to close this offering for a period of time until the currently on order components arrive and I can replenish the stock. Whether I can maintain an open wave or have to open and close this offering as multiple waves, only time will tell.
The price on these titanium SunDrop XR-U lights is $440 plus shipping*.
These lights are available on first come first serve basis; as determined by e-mail orders I receive which are clear, concise and include the must have information:
In the subject line of the E-mail please state: SunDrop XR-U
Your CPF name (if you have one)
Your real name and mailing address
phone number if international shipment
Any exceptions to standard shipping, which is priority mail.
If the shipment is domestic and you want insurance, please so state. (No insurance offered on international shipments)
For my general info on how I process these offerings, please refer to THIS THREAD.
Note:
The SunDrop 3S is compatible with a single cell battery pak. The converter is a buck/boost driver capable of running from a single primary lithium or Li-Ion battery.
* shipping is via Priority Mail with Delivery Confirmation or Global Priority mail. If you wish shipping via an alternative method, or signature confirmation or insurance on domestic shipments only, please specify in your e-mail order.

If you would like to order a SunDrop XR-U 2xAA flashlight that will have a 2xAA McClickie battery pak instead of the stock 1xCR123 McClickie Pak, the price will be $480 and please specify SunDrop XR-U 2xAA in the subject line.

Hi guys, I now have the original SunDrop heads also on hand so you can order either a SunDrop XR-U or SunDrop. Same price and both come with the latest Nichia High CRI LED I have been building with.The XR-U has roughly a 50 degree beam angle whereas the SunDrop has approximately a 75 degree beam angle. Below is a drawing set showing the physical differences between the SunDrop and SunDrop XR-U head:
If you want to get a SunDrop instead of SunDrop XR-U, then use the appropriate designation in the subject line of your order request: I.E.
"SunDrop" as opposed to "SunDrop XR-U"
If you have any questions, please post them at the end of this thread.

Hi guys, it's about dang time I updated this first post!! The SunDrop XR-U is still available but wioth contemporary LED's.
For the stock 1x123 complete SunDrop using a Nichia 119 or Cree XP-G2, the light is $440 plus postage. For a SunDrop with the XM-L Cree, the light is $445 plus postage.
Since I am onlu using the SunDrop XR-U head these days, I will often identify it as just the SunDrop. The original SunDrop head is no longer in use.

). The converter can handle the Vin of a single fully charged Li-Ion battery.
