Hmm so you also got 7000lm? Which battery have you used? But apart thah, you got a weird looking graph… why is it jumping from 100 to 20% three times in just 1 minute?
Hi, I activated the turbo voluntarily every time the intensity fell below 1,000 lumens until I reached a temperature above 60 degrees before restarting turbo, the third time it was already exceeding 60 degrees long, so I didn’t give it a fourth. Lumens are at 7,000 because the battery had already used it a little and comes down fast. This flashlight I have seen that to give maximum lumens is very sensitive to: 1. battery voltage, 2. cleaning contacts and 3. compressing the springs. In fact right now testing with the flashlight: 1. as is and screwing the head without squeezing hard I measured 7,500 lm, 2. cleaning the tube/head contacts and squeezing strong 8,500 lm and 3. inserting a 12×2 magnet into the negative 9,500 lm. I encourage you to take the test, it’s very fast and you can comment if you exceed 9,000 lumens. ____The lumens I have obtained with a white pvc tube with two angles of 90 degrees and the ceilingbounce app. These are of course only approximate, but the mode-regulated flashlights that I have used to check show readings very close to those published by the manufacturer. In my lumen readings an error of 10% can be expected.____ Here the graph and Flir images https://www.youtube.com/watch?v=Lu_7LV0tk-c

Are many trouble shooting options available for this light, i have been at ti for a few hours to no avail.

Sometime i twist the head on and it ramps up, suggesting an issue with the issolation between the switch signal tube.
sometimes no light at all, but with the initial flash as you screw the tube on.
Sometimes nothing at all.

Hi, try to clean all metal contacts, both those on the tailcap (metal ring) and springs.
Then, pressing the clip towards the reflector (to make its o-ring sits flat on the thread), screw the tailcap as tight as possible. Then tighten it even more. Check if the clip’s o-ring sits perfectly flat. If not, press it again and tighten even more.
Then rest. Listen to music if you like.
After all of that, check if it works properly.

Sorry for the belated reply mate, its been a nightmare down here.

Thanks for the suggestions, the problem seems to be intermittent to the point of writing off the light, i brought it through Neals Gadgets so im not even gonna attempt to contact him.
I will keep the battery out of it and only use to show people the wow factor, but beyond that i feel it to dangerous to put into rotation.

Cheers.

Got one, like it a lot.

In stepped ramping, which is the highest level that doesn’t do PWM with direct drive?

I've detected 3 levels that doesn't do PWM on the FW21 Pro (3x XHP50.2):

  a) on battery insert (smooth ramp mode only), I think this is 1x7135, probably around 150-170 lumens
(on stepped ramp mode, none of the default 7 steps matches this 1x7135 level -- which is between step #3 and #4 of the default 7 brightness levels)

  b) on default max ramp (ceiling, smooth/stepped), I think this is 8x7135, probably around 1300-1500 lumens

  c) on max (Turbo) level = NoPWM (max lumens depends on battery, and on how good is the contact of the battery and the spring (tightening the retaining rings can improve output a bit, if it was not very tightened from shipping condition)..

Yes, those 3 levels obviously don’t have any PWM, but it is still barely visible even on the lowest level.

Has anyone ordered the new sst40 version of the fw21 pro?

I’m looking at Neals Gadgets and want to know if it comes in 6500k or 5000k?

I’ve seen a review that said 5000k, but that person ordered directly from LT. Neal hasn’t responded to my question about the cct..

Wow, thank you so much for those quality side by side photos andreas0401 !! I am very glad to hear that the sst40 version you ordered from NG is 5000k ! Because i couldn’t wait and i ordered yesterday anyway Innocent

The sst40 5000k looks great! that was what i was hoping for, as i already had the XHP version.

By the way, i need to figure out how to make GIF’s like that for here on the forum. i know how to post pictures, i use imageshack to do so.

Really like this light been my go too for awhile now. But I would like the tint to be a bit warmer 4k.
Anybody know of any info about swamping the LED’s in this light ? And I prefer the flood beam of the XHP50.2 over the SST40 for my use.
!!
I think it took three wraps to get the 40T to fit nice and snug in the tube. I like it so when you drop the battery in the tube the air gets stuck behind it and the battery slides down slowly.

Dedoming the LEDs will reduce the colour temperature but also increase throw and reduce brightness by about 10%. I don’t think anything below 5700K exists for the 3V XHP50.2. The ones that claim to be 5000K are ususally just a bit rosier which is nice but still not 5000K.

Well now I know why they only came in the cooler tint. You learn a new thing everyday never knew that about the 3V XHP50.2 thanks.
Looks like its staying on the cooler side which is fine just thought it would be better around my sweet spot 4K. Not sure it would be worth the effort just for a rosier tint.

So all the XHP50.2 FW21 pro lights came in 5700k only? Maybe I have 6500K version I could not find that info anywhere.

thx

My first copper light I think every new light will be in copper from now on.
I just wish it would patina faster as I like that old look better than the shiny look.

Update: Lumintop just got back to me about my tint question with this reply “Hi, this FW21 PRO Copper we only have xhp 50.2 led with 6500k”
So looks like I could go warmer as Cutters here in Aus has 3v XHP50.2 in 3b 5K sweet.

But I cannot seem to get my bezel off my light has anybody pulled this light down yet? I cannot seem to find a review where a reviewer pulls the light down showing the emitters does anybody know of one?
Just trying to see what these LED’s are mounted on so I order right. Hate to order bare led’s to find out they are mounted on single boards.

Hey Rat, that FW21 in copper looks sharp. I have a bunch of xhp 50.2 emitter lights so I’d probably want sst40. Where do you get those battery wraps from? I have FW4A & FW3A so I’ve been tossing up between the SBT90.2 FW90? or whatever it’s called but now ive decided it’s gonna be copper for sure.

You mean this top part that has to be unscrewed to change LEDs? Because it can be pulled out easily, just like FW3A series, I unscrewed it doing the review, to show the inside, but unfortunately, when screwing, I destroyed all LEDs, just annihilated them… So I decided to not show it. Silly

Yes the top part. Mine is stuck on very hard. I run the light on high multiple times to get it nice and hot than used rubber strap wrenches but still would not move. Maybe the copper version is different.
Have you still got a picture of it with the top and reflector off?

The FW21 ×9L (SBT90.2) also comes in copper. I think I will be getting that light next when it comes on sale. The copper KR1 also looks nice and sounds like it performs.

The scale wraps only took 8 days from aliexpress Here
I also use black wraps to get the battery a little thicker Here
The next one I do I will try a black wrap, than skull wrap, than a clear over that or it could be two black to get the right thickness I cannot remember how many I used on that battery.

thx

I dedomed my fw21 pro xhp50 before I sold it a few months ago. They are mounted on one board together. If you get bare 3V xhp50.2 leds you will be fine. You do not need to get a board. And I don’t know where you’d find a mcpcb like the fw21 pro “off the shelf”, I tried emailing lumintop to see if I could purchase a couple extra mcpcbs from them for the fw21 pro, but they never responded to me..I was going to mount 3 osram CULPM1 emitters on a second mcpcb so I had 2 different mcpcbs I could go between. The osram CULPM1 and culnm1 are both 4040 footprint like the sst40, so would be an easy reflow if you had the extra mcpcb

So.. the appearance changes a lot. The tint changed approximately 1500-2000 cct, it will look like less than 5000k after dedome. The only concern is, it also turn quite green.

If you want it less green after dedome, You can order small sheets of Lee’s minus green from a member of blf here (https://budgetlightforum.com/node/42208) which will help counteract the green. If you do get the Lee’s minus green, go with -1/2. I did the -1/4 and I should have went more.

I loved the look after dedome at first but then after getting more lights with lower cct emitters, I realized how green the dedomed xhp50.2 is and ended up regretting the dedome. But if I had the appropriate minus green filter it would’ve been fine.

Remember, you will lose approx 15% output dedoming, but you’ll pickup about same % in throw.

If you have a heat gun, heat the bezel on medium / medium high for a couple of minutes. That is what I have done for inset stainless bezels that are hard to remove and it works every time. Also, if you have rubber heavy duty work gloves that helps a lot too.

Thanks, good to know. I was wondering and still do about what tints I should get for dedoming here:
https://budgetlightforum.com/comment/1752827#comment-1752827

Because those three options won’t be that much different, I wonder if any of those will result less green. Maybe I go with 6000k’s and see what’s what.

Sounds like a plan.
Thanks for all the info. I will try the heat gun next. If I get it off I will order the bare LED’s.
