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

Sounds good man. Good luck. :+1: :beer:

Great news! It’s good to know it was fixable with a slight mod, and no need to buy more parts (or scrap parts already bought).

Best one this month :slight_smile:

Ok, Quick update.

After another marathon sphere building session with the whole family helping out we managed to get all the spheres built, calibrated and packed up. Tomorrow I will start the shipping process.

Now to go fall into bed….

Thanks for all your hard work TA

Nice going TA!! . :+1: . :beer:

Wow, ahead of deadline and under budget. :+1:

And let the Shipping saga begin!

Tracking numbers should start going out via paypal over the course of the day.

Within the deadline but I wish it was under budget, more like way over budget in both costs and massively over budget in time. :weary:

Wow, I can’t wait……

Thank you

:+1:

Lol, I was thinking from consumers point of view. We got it under budget of what it actually cost. Plus I was not expecting it to be done so soon.

From your side of project: way over budget in both costs and massively over budget in time.

Sorry about that. You have many happy customers, though. :beer:

lol, true. I try my hardest to stick to my word whenever possible.

Got the shipping notice from UPS… :+1:

Thanks T/A! :beer:

Thanks for your hard work i’m sure it will be over my expectation. Next projekt you do…… I’m in/ Micael

Thanks TA. I will cover shipping to WA and NV.,

Great work thanks TA! I will also cover cost of shipping. Just let me know how much.

Ok, just got back from the post office / UPS.

All the orders should be shipped now and I think they should all be delivered by Monday except the international orders. If anyone has any issues please let me know.

Please post your lumen results, this is the first time I have had any direct comparisons with my sphere and others, so I am very curious what the results are.

The nice thing is that since they are all calibrated the same, if it is determined that the readings are off one way or the other, we can apply a correction factor equally to everyone. I have zero attachment to the “base calibration” of my sphere being accurate to ANSI specs since I have never had a way to compare it. So if we find a better calibration I am more then happy to adjust. This is simply the best I could do with what I had.

Now to clean up the mess all of this left behind and then start back to work on the mods.

When things go this way for me—-I justify it by saying—Education is expensive—Experience is PRICELESS
But being past the middle of 50 I try to limit my Education as much as possible

In other news someone sent me an LT300 lux meter to calibrate with these spheres. I had no idea what the results would be but after calibrating it I was quite happy to see that it lined up surprisingly close to the HS1010A meters I was using.

They were within ~5% across the range of outputs and lights I tested (I had 5 “standard” lights I was using for calibration, the only regulated lights with consistent output I had + an MT03 TA special).

The LT300 did seem less effected by tint and CRI, the warmer and higher CRI tints are where I noticed the highest variance.

I am waiting to see what this person gets results wise in his own testing but I was quite happy with my choice of lux meter seeing as it was 1/10th the price. The LT300 costs more then the whole sphere, even at the new price.

lol, yes very true indeed. If I did this again I would at least know what I was getting into and could plan accordingly.

Luckily I knew to plan on some problems so I built in some padding to the price so I at least did not loose anything.

I basically ended up making slightly over minimum wage for my time and not much profit on anything else all said and done with my not yet complete math.

So not something I regret but not something I would do the same way again for the same price.

I have a few ideas to possibly make the whole thing simpler if I ever need to make more. For now I am putting the whole thing out of my head lol.
