I was talking to DB Custom and Robo819 over on this Thrunite TC20 thread about their lumen tubes built by Manxbuggy1. Robo tested his TC20 in his tube and Newlumen tested his TC20 in the TA tube (0.7 correction factor). The result was only about 10% to 15% higher in robo’s tube. Not the 30% or so I was thinking. So that’s good news.
DB was thinking of sending me a light to measure in my tube then send it to Robo so we could get some comparitive results between the 2 tubes. I suggested he send it to you since your tube is a bit more accurate than the production ones we all have. Anyway, I hope he contacts you about it.
Robo819, DB Custom, TomE and Richard at MTN Electronics all use the same Manxbuggy1 calibrated tubes. Robo has a ton of light reviews here as well. So if we find out their tubes read X% higher than the TA tube we can calculate their lumen readings to ours (since I believe ours are more accurate). That would be pretty sweet. :partying_face:
The Manxbuggy1 tubes don’t use any diffusers, though. So their readings might vary a bit more based on a throwy or floody beam pattern. I’m assuming this, it would be nice to see if it’s true.
TA, I also whipped up this picture to show people one of the big design points in your tube to help cancel out the different beam shapes. I think it’s what gives your design the edge over other designs. You can use it in post 1 if you want.
