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

Yes… I want 3. 100% sure. I can send deposit right now.

Great, just wanted to check.

It is looking like I might need to make all 30 spheres which is going to be a much much larger investment then I planned on, so I might end up needing to take payments in advance afterall although I would prefer not to.

I will see what the grand total works out to in a week or so after people have more time to sign up.

Might also need to see if I can find another sheet of this diffusing film if this keeps up.

Good idea. $100 deposit for each tube sound great.

d-c-fix snow

Any idea of what shipping to sweden would end up at?

This is what I was considering until I found these diffusing sheets. They seem to work better then the DC fix plus they fit in the PVC without a separate piece of glass.

PM sent.

I’ll get you some measurements later today. Could you please PM me about shipping to Canada? I am tentatively interested.

i mean low lumen not with sphere, with this self-made pipe

Great job TA!

It doesn’t matter how low lumens the pipe can measure. You can just measure a middle or high mode in the tube and calculate the low mode lumens from the lux ratio in a smaller box or even measuring straight from the hotspot. Of course it’s not as straightforward as looking at the number on the lux meter.

you are damn right ) i use this ratio sometimes, dont know why it didnt came to my mind this time
thanx

$300 deposit PayPal sent for 3 lumen tube. Thanks.

In for 1.

Always wanted a way to truly compare my builds to others here on BLF.

Let me know if I need to pre-pay.

Thanks.

Added!

I will post when I am ready for payments, I want to get all the details figured out on exactly what I am ordering and how many first so I have peoples money as short as possible.

I figure I will give it a week or so and see what the interest level is before nailing everything down. Right now I would order 20 but if we push past 20 in the next several days I will go ahead and order 30.

Plus I am going to go see if I can get that other half a sheet of the diffusing sheet, in which case I might just go ahead and order 40 of them and sell whatever is left over without shipping included in the price until they are gone.

All depends on how much interest they get in the next week or so.

Yes. We should prepaid. I did already…

Thank you Texas Ace for doing it. I think it’s very valuable to have a set of cubes which measure the same spread around the world.
I’m not into this stuff deep enough to buy one yet (and recognise that I may be losing my only chance), but I love it nevertheless.

I am very confident you will sell 20. If not, i would fill the gap. Guarantee.

I plan to get some PVC quotes tomorrow for both the normal and larger size and hopefully see if I can get anymore diffusing sheet (If I offered the larger tube option I would need more for sure).

Saturday I plan to take a trip to the laser cutter and 3D printer to get a quote on those.

I have an idea what the prices will be but I need to confirm.

I am also talking to a few suppliers about getting express shipping on the lux meters so we don’t have to wait forever.

Once I have all of that nailed down I will start taking payments, most likely this weekend.

Just to make sure I understand correctly TA.

  • YOU will tell us when & how to make payment (downpayment / prepayment).
  • You “might” offer a ‘tube’ large enough to accommodate a GT sized light.

Is this correct??

Thank you TA……… :+1:
