By the way in the article you mentioned about Profoto B1.
Profoto B1 is not suitable for parabolic modifiers due to its strobe head design which send most of the light forward than to all direction. I am not sure if frosted dome can spread the light evenly. But let's your test results.

With the glass dome, they are still more directional than a bare flash tube, obvious if you pop the flash looking at in on-axis, vs 90 degrees off axis. The frosted dome is also going to be a much more diffuse source than a bare bulb. From what I've seen though, the D1/B1 seem to get the desired effect inside Broncolor Paras. It may not be exactly the same distribution or softness of light as with a bare flash tube, but I've never seen a side-by-side comparison.

I have the Parabolix 55" and deep 30" headed my way, and I'll be using them exclusively with the Flashpoint Xplor 600. I have the handheld extension head, which is what I plan to mount on the focusing rod, leaving the power pack at the base of the stand.

B1 will get minimal effects on deep para because it needs more light to the side and to the back.

I second what the others said, i.e. a Profoto B1/B2 will not produce the ring light in the defocused position which these modifiers are known for. Putting the glass dome on the B1 will help, but it will not yield nearly the same result as a bare bulb design.

We did think about the bare bulb vs recessed reflector and have shared our thoughts on the blog.

I did consider that, and tested prior to buying. I could not find ANY first hand info on the combo while doing research, so we did some ourselves. @ezzyz and I did testing on rental units prior to my buying the Para133, and came up with a sort of "workaround", though not optimal and pretty expensive.

we are doing more testing, but in short, you can still get a similar effect from the recessed flash tube and integrated reflector of the B1's and B2's if you can get it out far enough. The result for B1's and B2's is identical the ringlight-esque catchlight is not as prominent with the B1's and B2's as it is with the Broncolor heads, but the qualities and characteristics of light from the two remain very similar, despite Profoto's recessed flashtube design in the B1/B2/D1's.

If it will not work with a speedlite or a Elinchrom quadra head it's useless to me. I parting with everything else in the future

Very broad ring light :)

Can you share too the light pattern comparison shot where all strobe on focus point position?

Parabolix makes a speedlight mount where 2 speedlights can be used with their universal flash bracket for their parabolix modifiers.

absolutely.

here's some comparisons. I dont have any of my B1's yet, but the 77-degree spread on those is identical to the B2's, so the result should be the same.

i've also added the ABR800 focused and defocused here. I just used a boom arm for the ABR and Einstein, as I only have broncolor and profoto adapters for the focusing rods.

ABR800 Defocused

So we see that fully focused, the ABR800 and B2/B1's have a very narrow, focused beam coming out of the para, without much fill. Almost like a large reflector (like a Magnum, but with a tiny bit of fill from the light bouncing around the inside of the para.

You still do get the parabolic effect from the B1's, B2's and D1's in the Para.

there are very subtle differences, but on the whole you do still get the same texture and general qualities, despite its recessed flash tube.

I did some side-by side comparisons the other day, and it's not a _whole_ lot different.

once I can get a model to help me out with doing some test shots to compare B1, B2, and the MobiLED heads all in the para133, i'll post them up

also, as @ezzyz mentioned, we do plan to do a comparison between the Para 133 and the parabolix 45 as soon as we can. If we can rent, buy, or otherwise get our hands on the Para 88 before then we'll compare it with the parabolix equivalent.

as in my writeup, we do expect that there won't be a huuuuuge difference to justify why you'd want to spend 3-4x+ the amount for a broncolor or briese equivalent.

The desired ring light effect is achieved when you have a large dark center. I think your images above proves it, just take a look at when you have a Broncolor MobiLED on the focusing rod.

Would be interesting to see if Parabolix can create the same ring light effect. If you can, use an AcuteB/Acute/ProHead on a Parabolix and do the same kind of shots you did before.

I must say, using a B2 on a Para 222 focusing rod on a Para 133 is very creative. And at the same time extremely unpractical. :D

The Acute heads will create that effect on a parabolix, and also create the "starbust" pattern on the larger 55" when mid-focused (see below).

ignore the shadows from the adapter cage -- the acute head did not have its dome on. With the dome, the shadows went away.

Second picture shows an acute head fully defocused on a Parabolix 55.

Here's one of my B1's, defocused, on a Parabolix 55. Doesn't achieve the "ringlight" effect when defocused, but will still work and create a beautiful quality of light.
