[Review]Lumintop FW21 Pro - 10000lm destruction

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…

my sst-40 version of Neal is 5000k

Man, SST40 looks AMAZING!!!

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

Wow your copper version looks sick!

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.

later

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.

later

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. :stuck_out_tongue:

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?

thx

The FW21 X9L (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
