Pretty keen for both of these. I’ll obviously need to do some reading as to setting up custom Anduril builds (eg. 65% FET + RGB), but looking very nice.

Is gloss white an option? Black is good, purple is fine, green seems not ‘special’ enough.. but really I’ll accept any color as long as it has the right components.

Aux board though should definitely be white or black IMO

This modification is beautiful! Like having a smaller Emisar D4S. I wish I had the equipment & time to do this, but life is in a bit of a mess right now (preparing for a move). But I’m hopeful this will eventually make it to production lights as an option!

loneoceans, the GB driver still has a sense resistor that adds significant resistance to turbo, right? Also, is the schematic available anywhere?

The schematic and source files will be up on my github and webpage as soon as I get them together.  The production driver has a sense resistor that adds resistance to Turbo. Based on some prototypes I’ve built in real-world usage, the total actual resistance in the power path including wire resistance, contact resistance, battery internal resistance, and other parasitics, the total resistance that the Lume1 driver provides to the LED is just a few mR higher in best case scenarios compared to the stock driver, or sometimes matches it.


The FET used in the Lume1 driver has a higher voltage gate drive as well for lower R_ds_on. This means that for the roughly ~30-ish seconds the driver is in turbo, the maximum brightness is either almost the same as the stock driver in most use cases, or slightly lower when used with a very high discharge, warm cell (e.g. VTC5A or 20S), with spring bypasses. So overall, yes the sense resistor does add some resistance in general; its up to you to decide if it’s an acceptable trade-off between the added features, or not. smile 


Thanks for the information. I’m surprised to read that. The resistor is still 20 mΩ? Would a different FET bring noteworthy improvements?

Honestly I’m not sure. Performance is critical, especially in the voltage range that I use the most (3.9-4.1V) with low Vf emitters.
At the same time aux LEDs are a must. So I didn’t buy any FW* light yet. Lume1 makes me think a lot about whether to get one.
Overall I have mixed feelings and considering it’s quite expensive light I think I’ll pass for now. But I’ll keep looking at it because even though it doesn’t exactly match my needs for secondary light I still consider it to one of the finest drivers ever made available. Thank you for that loneoceans!

And I’m looking forward to see it being available in other formats – my Skilhunt H03 has been waiting for a couple of years for a good driver. I almost bought a driver from tamagotchi at some point but UI just didn’t cut it.

Field test - I went for a long bike adventure and I used the FW3A with the factory Lume1 driver as my main bike headlight. 

https://www.aliexpress.com/item/4000741932429.html?spm=a2g0o.productlist.0.0.559a6b53k0UCgw

I used a bike computer mount with integrated flashlight holder like the one above.

 

For the test, ran the light at various brightness for about 6 hours through the night across a variety of terrain. Not anywhere close to a scientific test by any means, but the flashlight held up with no issues, and I wanted to test the durability of the driver in high vibration conditions. I was happy with how the flashlight performed. Obviously though, the beam pattern is far from ideal as a bike light since a tighter hotspot would be better suited for the purpose (a triple Carclo is a little too floody for this), but that wasn't what I was testing for. As a side note, I've used the Convoy S2+ which works better, as well as the Sofirn SP31 which is a little better as a bike headlamp. 

 

Neal has agreed to look into improving the PCB quality of the Lume1 driver, so I hope this will be in final production soon. Thanks!

I think to use FW3A with same mount on my bike helmet. I think it is perfect for that of use with flood light and low weight.

Before I lose my idea, I think it would be nice for the next Rev. (should only FWx variations of the Lume1 will be available for the time being) to have 2 solder pads for an independent/discrete e-switch along with the FWx inner e-switch contact ring on the driver being connected via a split-pad (as the ones currently not in use) thus, user "configurable" in case the driver ends up in a host with no inner tube for the tail e-switch like the FWx host features the ring could then be disconnected electrically from the host's body tube and the discrete e-switch could be used instead.

 

Looking forward to install one of these in my Manker U22 II (Osram Flat White 1mm)  Not sure what's the driver diameter though as of yet as the body is glued to the head.. Flat Stare

(eh, scrap that.. A bit of heat and 5 minutes later, revealed that the driver is actually a 23mm Diameter - haven't gotten much further though, as I suspect the bezel as also glued and for now I really do not want to mess with the centering and everything emitter side)

Aaand.. other lights ofc.. D4SV2 comes to mind, GT Mini, etc.

 

[EDIT]

Factory Reset - Maybe configure one of the split-pads as enable-disable "standard" Factory Reset if the driver is not used in a FWx host ?

 

[/EDIT]

 

 

Cheers!

The drivers are currently being fabricated for production as of a week ago. Unfortunately I haven't really been able to get much details from Neal since it appears that Lumintop is the one actually manufacturing the driver with their partner fabrication houses. I've been trying to get a detailed timeline from Neal but as mentioned, it looks like the initial offering is to have the Lume1 driver as part of some special edition FW3 flashlights, and I'm strongly suggesting to Neal to offer the drivers for sale as individual drivers ASAP. If you contact Neal directly, it can help us let him know the interest everyone has for the driver :). 

I'll continue to give more updates as I receive them. In the event the drivers take a little too long, I will reconsider another separate group order.

Man i want some of these drivers so bad.
Ive got something like 12 FWxA lights now with every LED you can think of.
Would love to increase the efficiency on some of them.
I really dont want to have to buy a new $200 light though from Neal…

Yes that would not be acceptable, so I'm really trying to make sure Neal will be offering bare drivers at least for sale to members, and hopefully RGB Aux PCBs. It's not very likely that Neal can offer tri-LED aux boards because there are too many possible LED colour combinations, so for those, it's probably best to order the board yourself and assemble it with the LEDs of your choice.

I sure hope Neal or Lumintop doesn’t have any funny ideas here. The driver sure as heck better be made publicly available. .

Another quick update - just got a message from Neal that the drivers are in preparation for sale and Lumintop / Neal will be expecting to begin having them on sale in about 2 weeks or so.

I'm not exactly sure what their plans are for drivers in flashlights, but Neal confirmed that he will definitely be offering standalone drivers for sale.

Thanks for your patience everyone!

What a good example of businesses being open to external ideas and expertise to keep products on point.

Thank you loneoceans and Neal/Lumintop. I’m looking forward to these offers.

Honestly it’s probably the least they could do. They got multiple new driver designs and dozens of new lights in their catalog all based on this one light.

Hello! Just wanted to keep more updates as I get them. It's moving along slower than I would have hoped, but I think I can't complain with everyone hit by the pandemic from supply chain to shipping and manufacturing. 

Regardless, yes, Neal will be selling the Aux LED boards (RGB version). I was recently request to also make some adjustments to improve manufacturing process. The answer I get from Neal about timeline is 'very soon', though he's also probably bottlenecked by Lumintop's production. Thanks again for your patience everyone!

Hi loneoceans – thanks for the update. I will keep an eye on Neal’s shop. I’m in for at least two of these and the sooner the better!

Hello all, finally I have more updates! Neal just received a first shipment of assembled Lume1-FW3X driver boards and RGB Aux boards from Lumintop:

Here's a photo I received from him this morning. I noted to them preferences from BLF members of the soldermask colour but it looks like they went for the same as the default driver - Purple. Looks OK with ENIG finish. 

I'm expecting more details to purchase one will be available from Neal shortly, and hopefully I'll get a sample from Neal to validate.

As usual, when I get more specific details myself, I will be posting them here. Thanks!

Thanks for the update!

I liked the idea of a less common PCB color, but the purple still looks pretty good.

Fantastic! I can’t wait to get my hands on a couple of these!

Did the separate LED RGB boards, the ones that could use hand picked colors, end up on the chopping block?

I think the general thinking was that it was too difficult for a manufacturer to produce, mainly because of the hand-picked colors part. I believe loneoceans made the designs available for anyone that wants to make their own.

I’m very excited for the lume1 and aux board.

Yeah! I do recall that. The question I guess was more aimed towards the boards that omitted just the SMD LEDs themselves, I recalled some mention of that being looked into for folks who wanted to do custom color mixes themselves, although my memory could be off.
