Texas_Ace BLF Calibrated Lumen tube / Sphere No math skills needed - Several spheres still available

4300 lumens at turn on seems plausible. My measurements on the stock Q8 ranged from 4700 to 5200 depending on battery. At 30 seconds it depends on the thermal limit set in the config.

Is 6000 lumens @turn on plausible for the Q8 with VTC5A?

Sure, the Q8 vary a lot between batches and even samples.

This guy’s a troll right? Clearly. Surely.

Try Try again until you hit 8000 —why not

When I shine mine right in my eyes from about 5 inches away…it seems like 8000 lumens…

+1

Bypass the springs, solder blob some Sony VTC5D’s charge them up to 4.25 and you’ll probably hit 10,000 lumen maybe more, or we’ll never hear from you again?

Just kidding! :smiley: :+1:

You slackers…… With my ‘stock’ Q8 I got 16,132.516 Lumens using my ’Bathroom Mirror & Fixture Bounce All Around Test’. :+1:
That’s BMFBAAT for short…… :wink:

It goes liks this.

  • 1. Place light sensor in a zip lock sandwich bag. This has 2 purposes…. to difuse light & hopefully waterproof the sensor in case it slips from it’s mounting position…
  • 2. Open toilet lid… both lid & seat. Mount baggie enclosed light sensor on back wall of toilet basin right above the waterline.
  • 3. Turn on Q8. Shine into BR Mirror at pre-calculated precise proper angle.
  • 4. Light bounces into BR Sink on to Overhead light fixture.
  • 5. From Light fixture back to sink, then up to mirror & over to tub.
  • 6. Then back up to light fixture & into toilet basin
  • 7. The light sensor, covered by a baggie; is waiting to record the lumen number of this highly recommended method.

Any questions?? If not………

…….That is all……… :wink:

Can you please supply a video or at least some detailed pictures—you lost me at flushing first

Sorry. I don’t know what I did last time… I got 5000 lumen @ start on my q8 Samsung 30q.

I cleaned the contact point with alcohol pads…

I just had an Epiphany—-I recently had a new Modad system installed at my camp—upon looking at this diagram I realize i can use the unused upper half for a perfectly calibrated HIGH LUMEN measuring system—I’ve attached a diagram—Teacher this method seems much easier than yours—i just have to go in the front yard and remove a couple clean out covers

Wow, I stopped getting emails about replies to this thread for a few days and it blows up naturally. :person_facepalming:

I skimmed the last few pages of posts but am not going to bother to respond to all the posts as most things have been answered by others already.

I will start watching this thread again now that I know there are new posts.

KG, while I am happy to help you work on my sphere, what you have now is clearly no longer my sphere. I think it would be best to move it to it’s own thread if you want help dialing it in. There are many people on here (including myself) that are willing to help educate you if you are willing to learn.

Wiping contact points with alcohol really works miracles. Today I received my Mini GT. At first I kept measuring about 500 lumens with every battery I thought I got a dud. Then I wiped down the springs with alcohol and got 1,140 turn on lumens! This worked several times on the TC20 when turbo stopped working correctly.

Sorry my friend… pictures are a strict no - no. This method is such ’secret & refined double naught spy type stuff’…. I dare not share pictures or video at this time. :wink:

I’ve never heard of a spring that dirty before. Glad you got it sorted, though.

Nice… 1140 lumen sound legit… jason got 1200 lumen…

Can i know which 18650 you using on the mini gt ?

I got 1200 on my sample mini-GT as well.

Yes… very nice. Unfortunately, i ordered my mini gt 2 days ago…

I think you certaily do win brother. Your device is clearly better than mine… no doubt. :+1:

Do keep in mind however, if there are ‘floaters’ present the intergration properties will change in proportion with the density of the ‘floaters’.

I think the formula to figure that is.

BS=T x ฯ x μ x ฯD ÷ F>§°

Good luck…. :wink:
