[PART 1] Official BLF GT Group Buy thread. Group buy officially closed! Lights shipping.

Thank you for the information, yes, please send me a PM with whatever information you get.

I am turning in for the night now. I will get back to you in the morning.

Send to Texas_Ace as well.

It actually looks like an honest mistake. Although he should read DO NOT SHARE LINK a bit better. I’m guessing he has never gotten a coupon code from Madmax or Freeme. They always make it clear not to share special pricing codes.

Madmax has been burned pretty good in the past from people sharing codes they shouldn’t have, but that is a story for another day.

Thanks guys. For whatever good it did… my work is done here. I’m worn out.

Good luck with all the remaining orders. I absolutely LOVE my GT. Thanks again!

You’re right, he’s probably been spanked enough already. Everyone makes mistakes, especially me!

On the tint thing, I call 4000K Warm White because it simply is not neutral, it adds color to white, which is not neutrality. Shine it on a pure white piece of typing paper and the paper looks orange. Shine it on snow and , well, don’t they say never eat yellow snow? In science, the black body is a radiant subject, I have read that on Earth, fresh snow is considered to be a near perfect black body as it has nearly 100% radiance. Pure white. Clouds rate exceedingly high as well. Pure white. Neither blue nor yellow, green nor orange, Neutral, in othe words. No tint. In my beamshot of the OEM GT shining at the moon which is partially behind clouds, the spot of orange from the GT can be plainly seen on the clouds, thereby furthering my explanation that orange is not neutral.

As a photographer I see this as a very important issue, the ability to shine a white light on something without changing the hue of that item. That is very important to me. I cannot call an orange hue neutral for that reason.

Perhaps some people’s camera’s cannot distinguish the slight differences, but I paid top dollar for a top-of-the line best in class camera that indeed can distinguish the subtleties, as well as having a professional monitor and a colorimeter to keep it honest. I DO know the difference between white, and not white. It’s a $5000 wedding dress that is rendered correctly in an image. I know y’all are all very happy to get the GT at the price point, as am I, and I’m not trying to say there’s anything inherently wrong with the light, but considering I pay $500-600 for my flash units that shoot at 5700K to expose an image properly, the line is a fine one. The camera I used to shoot those beam shots just happens to be the best low light camera Canon makes, period. The lens I chose is also among the highest quality offered, so please don’t insult the photo’s by assuming a camera cannot detect the subtleties of hues, it’s really not plausible to get a better result at any price.

wimmer= the peace maker
good job sir wimmer :+1:


….and calm the raging mobs…………

Nodoubt…… ‘nodoubt’. :wink: . +1

Thank you for this explanation Dale!
It is the only thing that makes sense to me concerning this color / tint thing.
If it adds color it can’t be neutral…. no matter what numbers say.
Works for me…… :slight_smile:

Since we cant really buy any big diameter mcpcb’s with leds already on them, here is some “old school” info on reflowing an emitter from Old Lumens.

And here is a newer style method from Matt (Vestureofblood/Adventure Sport Flashlights)

There are also many other videos on YouTube showing how to reflow emitters. So if you were wanting to swap to a different color xhp35-HI or to a xhp35-HD, this is how you do it.

I don’t think Lumintop will be offering any extra parts for at least a couple months. So once someone starts offering a complete package that just requires soldering 2 wires, I’m sure it will be posted.

DB Custom, i think we don’t have intention to change your definition of WW vs NW.
But you are in BLF GT thread, and right now we have a GT model that is using NW XHP35 HI.
When we perform test on a DUT, we label it correctly to avoid confusion.
Your post labeling GT with WW XHP35 HI as stock light might confuse people who jump into it without knowing you don’t really follow standard definition CREE and other manufacturer adopted for their LED.

No one has said NW is pure white. Being not pure white doesn’t mean we should call NW a WW. They are steps from cool to neutral to warm.
CW or WW are not pure white too.

Sure you have very advance DSLR there. In different lighting environment, it is not easy to get pure white from camera without a white balance card. Maybe Canon has improved so much that its auto white balance is very good nowadays.

Rule one.

Proprietary color balancing from the digital camera I’d imagine.

I have just noticed an issue with one of my gt’s battery carriers. It appears that two of the four upper recessed contacts are not connecting (or at most sparsely) to my batteries button top. I have 8 identical Samsung 30q button tops purchased from mountain electronics. All of the contacts in one carrier and half of the other one makes good contact. It seems the two button top with issues stop about the distance of the width of two human hairs. I only noticed by shining a flashlight behind the contacts and seeing light pass through two of them. The only reason I checked is because I took one carrier out to charge the cells and reinstalled the empty carrier to run off of four cells only. I couldn’t get the light to come on. Has anyone else had similar issues? It may be that the 30q buttons don’t protrude enough. No big deal, I fixed it with magnets.

MAYBE YOU MISSED THIS BLANE……
This means you too………

It is the low height of the button tops.
I was worried about the 35E when I saw them. They just barely make contact condidering how much (little) button top is proud of the insulating washer & clear re-wrap.

Fabulous write-up DB. Thank you for that great info!

Ok, I was a little angry with him many pages of comments ago.

I made this comment many pages of comments ago when it was first revealed what had happened.

Another way to look at the color temp is like 0 degree centigrade is the freezing point of water, it also just happens to be the melting point as well. Since 4000k is the dividing point between neutral and warm white, I see no issue in naming it warm. 3999 is warm white while 4000 k is neutral white, but there is no way I can tell the difference between them. Just my thoughts and ramblings. Cheers!

Thanks for the info. I will do just that.
