Fireflies ROT66, Born for fans of flashlight

[djozz]

Got my ROT66 with Nichia’s, really nice!
Output at switch-on (it takes 3 seconds before the first read-out): 4300 lm, at 30 seconds 4000 lm. This was on freshly charged 30Q’s.

Wait is that Djozz lumens or calibrated lumens?

[djozz]

Djozz-lumens corrected for a 90+CRI 4000K light from maukka, which is minus 10. But please keep an error of 5, you never know with lumens

Do you have D4 measurements djozz?

I seem to have a freak ROT66.

I do not have a stock D4 left (I do have a pretty :sunglasses:
one with LuxeonV’s though ), but I trust my ROT66 measurements to be correct within the 5% that I stated above.

Yep that must be it, only explanation. :innocent:

This gonna be good

Good lord man…. You don’t have a freak Rot66. You have a wildly inaccurate measuring device.

@SKV89

Steel_1024 measured 4,880 lumens with his TA Lumen Tube but not sure if he has a set of the Maukka calibration lights to confirm with. The TA Lumen tubes that weren’t calibrated with the Maukka lights were reading too high.

Charles Lin measured 4,740 turn on lumens and 4,300 at 30s with the TA Lumen Tube. But it might be his TA Tube also does not have correct calibration and reading too high.

I took time redo calibration for my TA tube. Now, my 219B ROT66 with 30Q’s measures 4440 lumen at 0 second, 3910 lumen at 30 seconds.

My TA Tube, ceiling bounce and my Lightbox all have the ROT66 way ahead of my D4’s and D4S. Just visually outside you can tell too. I hope my youtube review gets it across.

I’m not going to your youtube despite the shameless plug but it’s not surprising that the more floody the light the more impressive and bright it looks.

You no longer have a TA tube. You have a box of your own making, calibrated as far as I can tell to some arbitrary factor to make you high lumen lights read what you “feel” is the right number

PLEASE, let’s not start over this thing again!

This is a thread about the FireFlies ROT66!

It has been nice to read the posts till here, even for a guy that doesn’t have money to buy this flashlight!… Let’s keep it that way!

Please, let’s keep the thread clean about the TA tube or KG lightbox or whatsoever!!! That issue is beyond contagious and exhausting for those that just want to read some things and see some beamshots…

Create a proper thread to discuss that, compare measurements, improve readings, whatever…

But please, let’s keep the other threads rolling about the issues they were made to present/discuss! In this case, the above mentioned flashlight…

Instead, give us some beam shot comparisons, tint comparison of the different leds, something the make us get and :laughing: and even :heart_eyes: , instead of :weary: or :person_facepalming: and eventually

Just saying folks…

^ I agree, and here’s a quick beamshot of my little square to get back on track , trees are at 25 meters.

That is a WOW
I believe the tree further away will be like 40-50 meters and still being quite illuminated !
This beam is one of the reasons why I like flooders over throwers!

Thanks for sharing djozz :+1:

They are not live yet, I’m trying to get the local sculpture park to let me have a wander around and capture some Patinas with the Rot66 Nichia on the Henry Moore pieces etc. It’s risky as the place is a hotbed for Cruising and Dogging.

I love the Nichia but I advise people to avoid buying the XP-L as a few are shipping with crushed LED’s inc my sample.

Very close to maukka specs… djozzz tube did pretty good too.

My tube is a very specially shaped tube, it is a spherical tube in a square box

[SKV89]

Djozz, did you calibrate yours with Maukka’s calibration lights? Btw, that’s a very creative lumen sphere.

Follow his link for the sphere builds. He built these way before Maukka was offering his lights, plus I don’t see his name on the order list.
