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

I do not have any Fenix lights but I am willing to snag one if you can recommend one over 400 lumens which works well. I have a feeling maybe I have too much 22 gauge wiring in my L6, I think I have 10 inches of wiring from the driver to emitter and maybe that is making a big enough difference, or a cold solder joint? My Hakko soldering tips are pretty old and worn. Hard to heat up joints good.

With a tail cap bypass I get 3200 lumens, very strange. I have a new emitter on its way from mountain electronics. Going to shorten the wires tomorrow.

Yes, this would indeed cause a significant reduction in output with that much 22AWG wire.

I have maybe ~3-4 inches of 20AWG wire in mine and that is pretty long for most L6’s. That combined with the GA low drain cells could explain the low readings.

Do you have some high drain 30Q or VTC6 cells? The LK’s should be better like said above, that is what I use in mine.

I don’t own a fenix lights personally (outside of my old CR123 EDC light from ~10 years ago) so I am not the one to ask about fenix lights.

No need to buy one for this, just figured you could test it if you had one. The Makkua lights are by far the best option for testing the sphere accuracy. They will leave no doubt.

The reflow on the emitter can also cause significant changes in output. If the LED is not permanently damaged this can sometimes be seen by a large drop in output in the first few seconds when the light is cold.

Great, glad someone was able to compare that light, I have not looked it up yet and don’t even know what it is lol.

I do not. Buying some 30Q now. Also just bought a Q8 that will be here Saturday. I figured the wire length would be an issue but I am not going to shorten them until I get my emitter hopefully tomorrow.

Sounds good, the Q8 is not the best comparison around since it is an FET driver but should give us a ballpark with a stock light to compare. I still have a stock Q8 here (well I reflashed the firmware), I still have not decided what LED’s I am going to put in it long term.

Let us know how the new LED goes in the L6 with the shorter wire length. I am curious what kind of current you are getting with how it is setup now as well.

Got a mess of stuff in this week, the maukka lights, 2x Manta Ray C8.2, 2x Cat V6’s LED Lenser P14.2 and some Vape CellVTC5D’s very cute zippered battery cases, oh and Hanks Quad boards and optics, named after a girl or something like that? Then working on the M1 “the Grater” Quad, running ragged!

My T/A tube is right on the money with the maukka certified lights, well it was something like the little light was 3lms. High and the S2+ 4lms. Low, close enough for me, really happy with everything.

The 2 V6’s were 1730-1744lm stock, with the stock battery @ 4.21amps of the Sky RC charger.

The GRATER M1 Quad Convoy!

A bit tired…. got to work in the A.M.? Maybe…. :wink:

Interesting M1 tube there, 21700? It doesn’t look long enough for 2S? Or does it just not have the threads cut yet?

Great video review VoB!! :+1:

.
Starting at around 6:10 Matt is using the TA Lumen Tube. He places the lights directly on what appears to be the first set of diffusers. Is this the “proper proceedure”?? From what I remember reading it is not.

But my question is this. If the light is placed on the first set of diffusers and the tube is then calibrated using maukka’s calibration lights , will the tube yeild the correct readings?

Got my Maukka calibrated and tested lights in today.

cw S2+ — 283.3 Maukka lumens — 288 TA Tube lumens

So that’s less than 2% out. That’s fantastic really, I don’t know how you’d expect much better.

The package also contains a tested BLF348, neutral white and only a few dozen lumens, but it reads a bit further out so far. I’ve not recharged the cell though, so I’m withholding those numbers until I’ve eliminated any other cause for them to be low. Its not fair to report them at this point.

So far though I’m very pleased with these results.

Thank you for the valuable information.

It doesnt look like a TA tube… i think he is still using his old tube with glass.

That is a tube he made himself. He shows how he made it in another video.

It is based on the older design that does not use any baffles / diffusers.

The above comments are correct. That tube is one a made a good while back. The readings I got for that light should be quite close, but the testing you saw in the video is basically the only testing I have done since my Maukka lights arrived, so don’t take it as absolute truth :innocent:

I might have missed this but TA are there any updates on the xhp50.2 you ordered?

Actually they showed up a little bit ago but I have not had time to mess with them yet. I am hoping to get some time next week to test them out if all goes well.

Oh OK, got it. :+1:
Thanks for the info Newlumen, Texas_Ace, & vestureofblood. :beer:

Nice, I’m looking forward to your review and possibly buying some if you post any for sale.

Yeah, I will have a handful for sale, just not sure how many yet or what they will look like.

I got my CW S2+ calibration light from Maukka yesterday.

It turns out my TA Lumen Tube was one of those outliers. It was reading 7% too high.

So I was able to adjust my correction disc orientation plus add a little piece of matte tape to get it to read dead on. :+1:

I also tested my calibration light in my JoshK sphere to find out it was reading 6.3% too high.

This is all pretty surprising. I thought both my spheres measuring so close to one another meant they were pretty close to accurate. Turns out they were both a little on the high side.
