So to show a mouseover and mouseout comparison between these 2 mouseover for the POB 35 watt HID and mouseout for the Vinhnguyen54 dedomed XM-L2 6.5 amp TN31. Now you be the judge. I know which one I'm picking for the one that won.
That pool wall says it all. This even surprises me. :bigsmile:
Unthinkable!
That means this Vinhnguyen54 TN31 mod will easily out throw a FF4.
That’s what I say.
To be fair I’m gonna go take another TN31 shot to show the same beamshots from the exact same nite.
I will find out soon enough. I have a TN31mb and a Vinh modified TN31 coming. I also have a Vinh modified TK75 with dedomed emitters. My TN31mb was measured at 400k. It will be interesting how the TN31 modded by Vinh stacks up and depending on Brad’s pictures I might order a K40 as well. The TK75 with dedomed XM-L2s might be the most impressive light I have though. I also have a modded Dereelight that slightly out throws the TN31mb. If I had a decent camera I would probably bust my beam shot cherry but no dice there. Maybe I can see if I can borrow one.
Ok here you boys go to be fair. I picked the best out of 4 shots. So both of these samples were taken on the exact same nite. So mouseover POB 35 watt HID spotlight mouseout Vinhnguyen54 dedomed XM-L2 TN31.
Again I’ll have to pick the Vinhnguyen54 TN31.
Does that guy pay you for turning his pool into a hot tub? Lol
I really want to see the k40 modded compared to these.
I heay ya! No pay yet. LOL!
I’ll show you some beamshots soon. Vinh told me in a pm at CPFMP that he can’t really tell much difference between the TN31 that he does vs the K40.
Now who said this vinhnguyen54 TN31 wasn’t 500K? 
Saablaster tested his POB 35watt 6000K spotlight on his light meter to be right at 531K lux if my memory is correct which I know it’s right at that number. I say mine should be right at what his was.
I was about right on the money. Read post #11 here.
I would believe the TN31 was 500k before I would the HID. They are both great lights but I know I would much rather own the TN31 that is really an impressive light.
I keep saying I’m going to spring for some better testing equipment but then I see stuff like this and read all the other stuff too and the only thing I am really convinced of is that no two people’s meters read the same. It’s one of the reason why I never post any of my testing information. I know my stuff isn’t accurate so why bother? My multi-meter helps me mod and my light meter gives me an idea of which light is brighter about as well as doing a ceiling bounce test with my eyes or just comparing throw.
I know the only light that I have that competes in throw would by my T90 That’s a 68mm reflector running 7amps with a de-domed XM-L2 U2 on a 20mm octogon. Even though I now have it focused nearly perfect I really doubt I am hitting 500k but I do think the TN31 could be, at least it’s possible. The T90 will put a round hotspot on trees that my BTU shocker’s flood at 300 yards was just lighting up. The BTU shocker stock just isn’t a super thrower in my book. I also have a 65watt HID and the T90 outthrows it easy.
This should be an awesome mod ILIKEFLASHLIGHTS. 
I have tried modding my SupBeam K40 myself but all I did was dedome the stock MCPCB with its original XM-L U2 LED and do a resistor mod (+ 3 R120 in parallel) which should give 6.77 Amps to the LED. I hope ILIKEFLASHLIGHTS won’t mind if I post beam shots of my K40. :bigsmile:
Stock K40 at 60 meters:
Modified K40 at 60 meters:
I just can’y imagine how better it would be if I do the other mods done by vinh. I’m still learning to do it for now. 
Hi Guys,
I have a crappy meter myself and the last time I attempted I got readings that were too high to believe so the 480K that ILF was referring to was measured by a friend over at CPF. Honestly I don’t exactly know what 480K would look like but I do know that a modded TN31 and K40 are among the best single LED reflector light there is that I know of. I do not have a lot of experiences with tons of lights so my opinions are limited.
I did saw a previous comment mentioning that I might be too busy or protective to answer questions of how I do my mods. I just want to clarify that I am very busy. Not with just flashlights stuff but with my official work and social life as well. However, I will answer any questions asked over at the CPF helpline thread I created. Usually though someone much more knowledgeable than I am will chime in and answer the questions thoroughly.
Numbers measured by different individuals induces all levels of uncertainty. The most dependable numbers for comparative sakes IMO are numbers measured by one person. At least then the numbers are relative to each other even if they are way off the truth. I myself couldn’t careless about numbers. To me numbers doesn’t quite speak justice as our eyes doesn’t perceive brightness in a linear manner.
Beam shots like ones made by ILF are much more intriguing to me. Thank you so much for doing them!
I would like to be more active here at BLF as I find more time. This place looks fun!
I could always be contacted via email at vinhnguyen54@gmail.com. I answer email most promptly.
Such tropical beam shots
LOL! 
I live in the tropics and my home is surrounded by thick vegetation.
I hope you won’t mind if I try to ‘copy’ your mod for my lights. It would be very impractical for me to send my lights to you all the way from the Philippines aside from the fact that it would be much budget friendly to do it myself. :bigsmile:
When I first started Dedoming I notice a sharp tint shift and or noticeable drop in lumen. Nowadays I think I have perfected the part of dedoming that I feel the lumen lost is quite negligible to the naked eyes. My methods are very simple and I might make a video one of these days show how I do it if there are interest.
Yes, please! :bigsmile:
That would be very interesting.
Great work on some amazing lights.
