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

Yes, it is not “budget”, nor is it a necessary tool for many of us.

But it IS a Texas Ace built and calibrated tool for accurately reading the output of various flashlights. The materials (including a measuring device—Lux meter), versatility, construction, calibration, accuracy, and work put into this device will justify it’s cost to those of us who desire accurate light output measurements with minimal hassle.

If Texas Ace is building it, you can count on it’s quality. I suspect the materials alone will be close to his costs and a small percentage will go to pay for his time and expertise.

In that regard, it may not be “budget” but it will definitely be a “bargain” for what those customers receive.

I suspect many would rather spend $100 on an awesome flashlight…and he makes those too!

I’ll take one. Would be great for all the reviews I do on youtube.

I'll take 1.

T_A, that's some fine engineering and tuning work you've done there! :) Congratulations on making a precision instrument from something that took a little "black magic" to just come close to actual numbers. Again, well done!

Where is the list T/A/ Sign me up, I’ll take (1) please. :+1:

Thanks, making the first sphere was a labor of love for sure. Many many times I wanted to just give up but then I would get a new light and want to know how much I was being lied to and would keep trying.

The naked LED tests were a key part of the setup and testing, it really improved the ability to get good numbers across the board when I did those and applied what I learned from them.

I will most likely use some naked LED’s on my bench for calibrating a lot of these since they are much more stable in output then most lights due to the stable input power and massive heatsink.

I think I have everyone added to the list up to now, let me know if I missed anyone.

Considering lawyers and engineers charge a couple hundred dollars an hour for their time and expertise, paying $100 for a quality lumen measuring device that requires a huge chunk of time for R&D and the TA quality is definitely a bargain. Also material and shipping cost money so I don’t see TA making much profit for this. Remember earning profit is not an evil thing. Everybody needs to eat and live. Some people put in time and effort at their job to get paid by their employer, while some people put in time and effort to get paid by customers.

:crown: :+1:

Those 4” PVC street 90s are not very cheap / plus a meter with all the acc to make it a working device not to mention that free shipping we all can aquire for something that big—- $100 is a steal—you couldn’t buy mine for a $100

This looks like a good way for people to get decent measurements… and it always helps when different people’s numbers can be compared to each other.

I’ll stick with my “Integrating Milk Carton” for now though, since it’s small and seems good enough for my purposes. :slight_smile:

in for one

This PVC has an ID of 3.5” at the opening for the light, I forgot to put this in the OP.

I will take 2 more. . One is for my brother and friend. Thanks.

With due respect, this was a completely unnecessary comment you felt the need to share.

It did have the benefit of people explaining why it IS such a good price. Plus maybe Mike will think it over and realize it’s not so expensive after all.

It’s not a product for everyone. It’s not like the GT where your going to have 1700 people waiting in line to buy one, but for a very small group of people, it is very worthwhile.

100 dollars is a steal in my eyes I can’t afford it. But if I could I would no doubt. To be able to test my own lights. Without having to mail my lights to someone to test and have mailed back. Would be much easier to have a kit already calibrated and ready to go. And it be the same calibration as 20+ others on here it’s only a good thing. Instead of ta lumens, dzozz lumens, speed4goal lumens etc. For the most part everyones results are directly comparable

Yep, very true! Good point…… :wink:

In, I’ll take one

Ok, just to confirm, that is 3 total correct?

Got it, I should have it updated now.

You need to set up an assembly line:
