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

I do not know how Texas_Ace can get so much done, has he cloned himself?

Very thankful to have him and his services in our Forum!

Out of curiosity for me and maybe others. How much would the lumen tube cost us for the bigger version to accommodate the blf gt? I don’t think this will be the last time companies will be making heads this large. I already have a few lights from acebeam and thrunite that are 4 inch. I believe olight and manker will also release some large head lights.

This looks very neat! I definitely do not NEED one, but the WANT is strong! Must think…

Thanks TA!! Sign me up please. :+1:

Is this design useable with right angle lights?

Vry Nice—-I’ve been using DC Fix in my light tube—-I still have a multiplying factor but my results are much more reliable and consistant

Hmm, that is a good question. I know the PVC itself was several times the price. If there is interest I will go to a specialty plumbing supply store and see how much it would cost.

Remind me to check into this if I forget, this week is going to be VERY busy for me.

Just let me know if you want me to add you to the list. If you end up sending me the L6 to mod I could ship them back together.

It should be, you only need the very tip of the light sticking through the centering ring for it to work. In fact sticking the light in even 1/2” too far can have a pretty noticeable effect on the readings.

Indeed, this version does seem slightly more consistent then the foam I used before and way WAY better then using nothing like I tried at first.

You are definitely getting the L6. 8500 lumens is too good to pass up!

I am thinking of designs like the Armytek Wizard where the cooling fins protrude in front of the bezel, preventing it from lying flat on a diffuser.

Yea I also want to know because I’m interested in the upcoming Astrolux MF03, MF04, MF05, TN42VN, and Acebeam X70 or whatever other high power lights might be coming out.

It will not seal perfectly but it should still give a reasonably close reading. You will just need to add a little bit for the light that escapes due to an imperfect seal. After some experience with the tube you will figure out a reasonable amount to add by playing with other lights of similar output and pulling them out of the tube slightly.

Ok, I will look into it. I don’t think I will get time to do this until Friday at the earliest, Remind me tomorrow if you can. I will be silly busy the next few days.

How about a spare diffuser ring with a custom cutout for the fins so it lies flat? I’m mostly curious because I do a ton of testing with modded Armytek headlamps so it’s worth the extra effort to me.

I will take one. Thanks.
