Hi guys,
It seems a good time to provide some background, potential options and a status update on the SunDrop.

First a little history. When I designed the SunDrop, I saw it as being either of the "x2" platform (PD style) or of the E-series (Aleph) platform. I knew it would have a limited and niche market and not be considered tactical, what so ever. At the time, Wayne was developing the GDuP and I felt the SunDrop, if offered in a multi-level version, would be ideally suited for use with the GDuP. I opted for the E-series platform due to all of the potential options and converter possibilities. Well as fate would have it, as the SunDrop components started coming in, access to converters and converter options became restricted.

At this point, a little more than half of the 100 SunDrop sets have been assembled and released to the community. I have ~45 sets ready to go once I have built the LE and it's simply a question of getting converters so I can build the LE.

For good color rendition which I believe is the primary role where the Nichia High CRI LED shines, I believe you need the LED driven at full power and a single speed converter will provide this. I have some GD converters on order with Wayne and Cindy and with these, I can build 1x123 SunDrops which will perform well on either CR123 or R123 batteries. However, personally, in addition to good color rendition, I also would like my SunDrop to be viable in applications where I have been using a mule and for that reason, I want less output as an option and a three speed is my answer.

A number of months back, I sent Wayne a request for quotation on a large number of GDuP converters. I figured first up would be the SunDrop wave and I could do follow ups as well as branch out into some other 3-speed designs. Well building a large number of GDuP's didn't fit with Wayne's business plan as it turned out and I was informed that if and when the "black out" period on the GDuP was lifted, I was welcome to purchase the converters from the shoppe just like everybody else. This was a reasonable decision on Wayne's part but unfortunately I couldn't make any plans with the uncertainty of access or availability of the GDuP. The first wave of SunDrops was in a single speed offering as a result.

In the mean time, I have been working with a friend in Japan who has a designer who has come up with a 3-speed buck/boost converter which works well with a single cell pak and the 083LED. I have a SunDrop proto hosting this converter and in the spirit of being a real weenie, I have mine! :nana:

I had hoped by now these 3 speed converters would be on order and in process. In reality, we are getting close but there are some real logistic problems and desirable economies of scale we simply can't meet. Broken reel quantities can be painful if even made available and less than reel quantities of a chip that needs to be programed prior to mounting is a real hurdle at the moment. It does seem that we can get there but these converters are going to be expensive and I anticipate a non trivial premium on any SunDrop I may be able to build using one of these. At present, the possibility of using a three speed in this first set of SunDrops is questionable and this is vapor in a rather volatile atmosphere. Because it is a possibility, however remote, I wanted to let you guys know of it.

Because the SunDrop head is of the E-series platform, in addition to using it with the 1x123 McClickie paks I already have set aside with the existing heads, I now have the option of using the SunDrop head with some 2x123 McClickie paks I just got in. To add to the momentum of such a consideration is the fact that I have plenty SOB converters on hand and can actually build an extended play SunDrop now with components on hand. Such an extended play SunDrop has the ability of running on 2xCR123 or 2xR123.

I don't see that I have anything to loose in offering to build some of these extended play SunDrop lights other than the fact that whatever I do here will reduce the size of the waves of SunDrops later unless I commit to another run of titanium heads and paks. Because the SunDrop is a niche item and the program has been haltered from the outset, I have no feel for the advisability of going for another set. Obviously the smart thing to do is wait and see how things go.

So to try to recap, as I see it, I have three primary options to consider in my plans with the SunDrop and ranked by their time frame:

1) At Present: Build extended play SunDrop using SOB 333 & 2x123 pak (1 speed light, any 2x battery set and a price of $460)

2) Soon (hopefully before Sept) build the normal SunDrop using GD 333 & 1x123 pak (one speed light, any battery and a price of $400)

3) Maybe (Sept or Nov) build a 3 speed SunDrop using a 3 speed converter and 1x123 pak (any battery and price unknown but likely around $450)

Looking beyond the next few months, I am very hopeful that I will be building more SunDrops of whatever configuration because I really like the light, believe in what it has to offer and not to hide anything, I have a good number of the sapphire lenses, LED's and LE components that need to be used somewhere! :green: :eek:

In light of the 2x123paks now being offered, it seemed a good time to update on the SunDrop and in the not surprising case I have missed something obvious, I want to open this up to discussion and comment.

On a preemptive note, this discussion is about titanium paks and heads. Aluminum hosts are not topical here. In addition, once I have converters on hand, I won't rule out the possibility of offering some LE's separately or perhaps at least included in any Aleph McMule EN sets I may still have on hand.

This was a long ramble and to any of you who made it this far, thanks. :eek:
 
Some great advancements and additions to such an already amazing system. something for everyone to keep their eye on
 
IMHO 2-speed would be enough for this light if it makes it any cheaper :nana:


Seriously though, in a 3-speed I'd think about a really low low ... think locator or night light.

Apart from that ... all options sound good. I do not know how many of us will need the extended runtime of the 2x123 pack given the fact that the 1x123 does offer some respectable burn-time, but more never hurts and I like lights that bring ne through the night on one set of batteries.

3-speed sounds nice but I'm actually more interested in the XP SunDrop. I think the ammount of light the Current 1-speed Sundrop produces is just about perfect and I'm not sure if I would ever use a lower level even if it had one (But that's just me, others may feel differently). The 2x123 Sundrop however, would be a true workhorse of a light and I would love to own one :thumbsup:

What is the runtime of the SunDrop anyway? I think I'm still on my first battery :p The 2x123 would be an awesome light for camping or a long blackout.
 
Hi Don, thanks for the memo. It was worth reading to the end :D With light of a possible 3-speed converter, will there also be 3-speed LunaSols in the future (something akin to your proto GDuP LS27)?

It will certainly have a long runtime. I figure (actually guess) that the 1x123 will run 2 hours continuous ... probably 5-6 hours in a 2x123. The lower levels would extend that number many times more.
 
All of these options sound very good.
Don I was wondering if there is any difference between the
2 SOB head options. Meaning can take the head off the 2 cell body and put it on the single cell body and get the same output? Is the difference in runtime based on the 2 cells or some difference in the circuit setup?

`I really look forward to your 3 speed setup. I see myself saving up some dough for this one. Would it be compatible with the 2 cell body?
I ask because I really would like to have one of the new 2 cell bodies and am aiming for maximum compatibility both now and down the road with your offerings..

I like the focus on the sundrop. I believe that many end users will appreciate the fantastic "look" of things when illuminated by the unique sundrop driver/emitter/optical system.

Have you considered a sundrop version with a LARGER lens?
The idea of more power and Bigger beam is appealing to me anyway.
Thanks for all of the heard work.
I will be making my request for a 2 cell body when my next picture starts...
Thank you again Don for the hard work and your consideration of your end users in determining your path.

Take care.

Hi guys,
The SOB is Waynes buck converter so it will not work on 1x123. I might work with a R123 but I have some doubts as I recently experienced with a SOB driving three LED's in series where the Vin needed to be in excess of the Vf to get the target current. I think the safe position is to state the SOB with the 083 LED should only be used with a pair of batteries and not a single one. If empirical experience from some of you is contrary to this, so be it. I actually got a bunch of the SOB's originally thinking that they would be an efficient option for use in LunaSol's made solely for R123 users. I ended up going with the GD buck/boost that could play either game.

The three speed proto I am working with has a Vin limit of around 5 volts so it will not work on more than a single battery. I believe the GDuP has a similar restriction. So, a 3 speed might work on a 2x123 pak if the pak is host to a single Li-Ion battery but otherwise, no.
 
...I won't rule out the possibility of offering some LE's separately or perhaps at least included in any Aleph McMule EN sets I may still have on hand.
I'd love to see a three-speed in one of the black EN McMule hosts. My favorite, and most used Mule, is the same host with a GDuP/Q4.
 
Since I just jumped in on the 2x123 McClickie and also have an EN Mule I say go for any and all options. A three speed would be most interesting and I am jacked to think I could add the Sundrop head to my recent purchase. I guess my kids can go to a state university. They'll understand.
 
.... and I am jacked to think I could add the Sundrop head to my recent purchase. ....

I don't want to give the wrong impression here. I have offered the paks separately and I think the offer has merit. However, my primary focus is on complete lights and I have no desire to get into offering all of the various components or partial assemblies like just a head (with or without LE). Now I have already accepted the request for a SunDrop XP (extra play with the 2x123 pak) and it seems I should just offer up a "build as needed" wave of these and let it run for a bit and see what happens. For those of you who have already purchased a 2x123McCP, I will offer you a SunDrop XP head for the additional difference in price ( 2x123McCp - $230 + additional $230 to get you to the SunDrop XP price of $460). Beyond that, I am not making any offer for just a head or whatever. Sorry.

I get many requests privately and typically they are prefaced with "it never hurts to ask". Well that is certainly true and I see no fault here. However, for some of us, it does hurt when we feel the need to say no and deny a reasonable request. There is often more involved and an interrelationship of components and inventory management which can be a challenge in the best of times and with a closed door, if that makes any sense.
 
Hi Andy,
No this isn't a wave here. I need to get my act together and I will most likely launch a conditional wave in the next day or so for some SunDrop XP's. Since they will draw from the same lot of 2x123McClickie paks, it seems I should make the offer now. These lights won't be ready for immediate shipment as I will have to build the Light Engines but since I have all that I need on hand, this can be quick.

That is a great offer, and I would very much like to buy a SunDrop XP head to put on the 2x123McCp I just purchased. Looking forward to the wave :)
