Thank you TA, I will re-read everything and see where I stand. I like the idea of keeping the charging. But if solutions for the light have been worked towards, I will def weigh the overall benefit to the light.

Will removing charging address some parasitic drain and the glowing LED, or just the residual drains?

WildTrail sent me these pics to share with you. I was also given a short video clip that shows the deep heat fins of WT90. Texas_Ace, maybe you like to put them into the OP, too?

Here’s the new link to the WT90 manual, please click >>> here <<<. The old links do not work anymore. Sad

It really is a beauty

I’m super excited for the group buy and everyone able to get one even though I’m not buying one (already have a silver).

Everyone’s gonna love this thing. It’s like a really pretty piston with a lightsaber coming out the top. It’s also got huge Art Deco swag with a bit of a retro museum-piece/trophy-vibe, let’s just say it’s an absolute classic.

So, i couldn't get any beam shots at the beach because of the flashlight paradox that happens at CT state parks where the sun goes down at 8:20pm, it gets DARK at 9pm, and the parks close at 8:30pm.. So these are from outside my house, distances measured with google maps. Unfortunately not a good amount of range, but WT90 looks like Daylight at 350 meters.

Now, zoomed in

now, zoomed in

and just for fun

Yea, don't have easy access for beamshots local here. I could use a park but technically it's closed after dark.

This is my problem, state parks have the best access to range other than pulling over on the high way! lol

I'm close to thinking to mod one with a SFT-40: 8-9 amps looks like the sweet spot and should be able to out throw a SBT90.2.

 

 

Oh wow, that would be Awesome! How would you limit to 9 amps? in the firmware with anduril 2?

I remember I bought 2 Lumintop SD75 that featured inboard re-chargeability AND power bank functions, though it had a much simpler design as the carrier was the usual 3-cell carrier with the charging circuit situated at the bottom of the battery tube.

Both SD75s had horrendous parasitic drain that it ruined two sets of 18650s. Perhaps more design research is needed to mitigate this problem, at least for me.

Personally, I will have to wait for the WT90 to iron-out this parasitic problem before I dive for this light as I am really a fan for this light’s design, performance and powerbank versatility, but a phobia for lights that has parasitic drain issues.

i was saving $$ to buy the new Lumintop top SD90 like 2 weeks before TA dropped this group buy! I wished the head was larger on that light because it looks pretty awesome otherwise. While I was trying to dig for info on it because it was new, I found 5+ year old YouTube reviews of the SD75, which seemed like it's predecessor but with the xhp70.2 . I haven't seen much about the sd90 since the WT90 came out. Interesting lol (it is $40-$50 more than the WT90 with a 10mm smaller head, which I equate to less throw).

it gets my vote, with the Emisar DT8 at a close second. But regarding value/thermal design/aesthetic (IMO)/ and performance: the WT90 is unparalleled.

Cochise334ever – not sure if I missed it – did the stripped carrier solve the problem, reduce the parasitic drain you measured before?

I will do the exact same test that I did with my old carrier for 3 or 4 days. That will be sufficient enough to see if there is a noticeable voltage drop. Just like the original test I checked the voltage after 12 hours of rest.

The Voltages after 12 hours rest is 4.21V for ALL 3 P42A.

I will check once a day for the next 3 or 4 days at the same time because I have OCD.

My guess is it will be the same three or four days from now..0.01V drop at the most.

Both tests were started AFTER 12 Hours of Rest after being Fully charged.

After 4 days the original carrier dropped from 4.23V to 4.17V. A 0.06V loss.

Below is Toms modded carrier that he swapped with mine.

Started at 4.21V and after 4 days was 4.20V.ONLY lost 0.01v.A typical loss not associated with parasitic drain.

Conclusion..SUCCESS Thumbs Up

Off to the dentist.

Disabling the charging on the carrier should remove all parasitic drain from the carrier leaving only yhe normal parasitic drain from the driver itself which generally takes 2 years+ to drain a set of batteries.

Sadly I do not see the charging parasitic drain being fixed while keeping the charging working. This is why I don’t care for internal charging. It can be done but takes a lot of extra work to make it work properly.

Thank you. My Google Drive links were unfortunately messed up by some update, so I had to restore some information, e.g. manuals. If you want to update the link to the manual once again, here’s the new link:

What is it about internal charging that causes parasitic drain?

The Charge circuit IC’s are simply not designed to have the low parasitic drain that we need. They are designed for items that are used regularly or need constant monitoring.

It can be made better but takes more expensive components and R&D that most flashlight manufactures are not even aware are necessary. Parasitic drain is something that manufactures seem to completely ignore for some reason. I have a few lights that from the factory would drain the cells in a few months.

Last night.

A lot of moisture in the air and even more haze from the Canadian and West Coast USA fires.

Across the River about 125 yds. To target, A Sycamore Tree.

Ok, just got word, this weekend will be the end of the group buy.

So anyone that wants a WT90 at the GB prices grab them while you can!

Quite surprised to see the slow sale of the WT90. The Black version hardly moves on Ali Express’s web page for days, still 51 pieces available.

I have grabbed one Silver. Will wait to get one Black if the price drops later this year.

BTW, what happens to those large and expensive flashlights (each costing over US$200) which have been left unsold over the years? Just saw on Olight’s website, soon the new X9R will be on sale for about US$500. What will happen to the older Marauder 2, which is priced over US$200?

X9R has been around for a while. Marauder 2 came after it. The only thing that’s new is that it’s blue now. I imagine they will continue to carry both models. The X9R will go back up to $600 when the sale ends.

The same thing that happens to anything that does does not sell. Flashlights are no different.

Hi TA, It is possible for a "mere mortal" without too much experience to be able to disable the charging on the carrier ... I wish I could do it because I always use a spare pair of batteries and I prefer to recharge the batteries with my charger.

For one, if I remember it well, Narsil has the option to switch off thermal regulation while Aduril can not. (correct me if I'm wrong). That alone makes it worth to have Narsil on the WT90 for me.

yes, great point, and you are correct about the capability of turning off thermal reg on Narsil. And I am pretty sure you cannot on Anduril, but I don't know honestly. And that is also a huge reason to have Narsil on the WT90, which I forgot about!  Thermal reg is also the biggest drawback to my mf02sv2... 

A way to turn off thermal regulation in Anduríl is run it on Turbo for minutes and tell the lamp it is 18 degrees C.

 

Excuse me how do I tell the lamp 18 °? I can calibrate the external temperature or the temperature of the room or you are telling me that after heating the lamp with the Turbo for a few minutes I tell him that the room is at 18 ° so that it who is hot thinks that all that heat is only 18 °, is that correct? Thank you.

Easiest way would be to simply replace the charging PCB with a pass-thru board. Should be cheap but Int'l shipping is always a problem. We do need the PCB board designed, then anyone could order it through a PCB service like OSHPark or a China based low cost PCB house like https://www.pcbway.com/. Not sure of the cost, but probably over $10 shipped.

This is about Anduril, not the WT90 flashlight as shipped.

With Anduril, to calibrate temperature, you tell it what the current light's temperature is by clicking "nn" times, like 18 times for 18C. So what he's saying is to calibrate the light way under what the true temperature is, therefore it effectively disables thermal regulation because if it's set to trip at 50C and the real temperature of the light is 50C, the processor thinks the temperature is only 5C, for example, and won't drop the output via thermal regulation.
