Glow EZ Lock Deep Parabolic 48″ Quick Softbox Updated 5-19-18

UPDATE 5-19-18

Zarli, a visitor recently asked me two questions, one of which didn’t take long to research and I’m assuming others will have this same question so I’m adding it here. He wants to know the diameter of the changeable speed ring in the unit. The measurement is 144mm or 5 2/3rds of an inch. If the light quality is as I expect I will change the Bowens speed ring to a Cheetahstand low profile ring. I’ve done this for all of my Bowens modifiers when using them without a focusing rod. The reason is the Cheetahstand Low Profile rings allow my Flashpoint strobe bulbs to penetrate further into a modifier giving me a percentage increase in light output. It’s a very easy change and well worth the extra 25 bucks.

The low profile speed rings I use.

You only need to remove one of the #2 Phillips head screws along with the thumb screw and loosen the other two to remove the speed ring.

Here it is with the speed ring removed. As you can see I didn’t have to remove all of the screws.

Figures a photographer would have a shitty photo of the ruler!

Just to show I can replace the Bowens mount with a Profoto mount. I have these Profoto speed rings to replace them when I’m using my Parabolix focusing arm which is the exact diameter of Profoto’s speed rings. Obviously I won’t be able to do that with this Glow modifier due to the rods. BUT the movable disk is intriguing me…..

Original Post

Although I have not had time to evaluate the actual light quality of this modifier, I wanted to give my impressions of the Glow EZ Lock Deep Parabolic’s physical build quality of the unit. As is my workflow, until I can test any modifier I won’t be using it on commercial shoots. Since this is my hectic time of year I’m not sure when that will occur. But once it does I will post my impressions here. And I’m not going to get into the fucking bullshit back and forth about whether this is a true parabola. If you’re one of those best of luck and start babbling about geometric facts somewhere else. My world is about creating compelling and excellent imagery, not having to be fucking right. Plenty of other troll places you can go online for that.

Ok…

Even though it’s marketed as a 48″ modifier, my measurements show it’s 46″ at the widest portion. Not a big deal, but if you’re looking for 48″ I didn’t find that to be the size of the opening. The outer fabric is a high quality rip stop nylon. I had read on some site that an individual didn’t like the yellow stripes and that their clients may disapprove. To each their own, but my clients could care less what my gear looks like, what I wear, what wine I drink, the brand of toilet I use ….blah blah blah. What they DO care about is my imagination, putting it into an executable and relevant concept along the quality of my imagery. 

I love it when retailers include a grid. Especially a high quality one like this. The squares are 1.5 inches and the grid fits very well in the rim of the modifier. No slop.

Just the other side, but I wanted to note that my 600 Pro holds this thing snugly and securely.

I always appreciate when the modifier fabric easily covers the speed ring. Not all do, but this one does. More about that zipper below….

I’m not sure why they’ve included a small zipper. Because of the rod that remains in the center of the modifier I cannot use a focusing rod where I would run a remote strobe head cable out of this opening. Perhaps it’s to make expanding the unit easier when opening. Because it’s DAMN TIGHT to open which is a good thing to keep the fabric nice and tightly stretched. Cussing level (4 of 7) to push the thing open.

I like to remove the rod ends from a modifier’s pocket to see the quality of the end caps. These are great and the pockets are deep enough so the rod ends don’t fall out unless you pull them out like I did to examine one. Also the width of the Velcro is nice and wide, about 2″. Even when I don’t use a grid, feathering light is much easier when a modifier has a wide dark edge.

The fabric is a shiny smooth silver made of a high quality rip stop nylon. I tend to prefer pebbled silver, but until I actually test the light quality I cannot say how it will perform to my taste.

In addition to the grid you get an inner and outer diffusion panel. As you can see they use a 2 stop circular piece of fabric on the inner panel to prevent hot spots.

A personal pet peeve of mine is when makers use those blasted infant clothing snaps on diffusion panels. Sure they’re fine to snap together, but a real bitch to take apart. I was pleasantly surprised that these are both easy to snap together AND APART. Cussing level 0 of 7!

This is the interior of the unit when expanded. The lock is very secure and almost identical to the Cheetahstand quick strip boxes I use. Very secure.

So Adorama includes this little disk which slides onto the rod using friction applied by a rubber ring. I “think” this “may” have a similar affect as my focusing rod modifiers. The marketing material states that the disk can be used this way or inverted to spread the light in a different manner in the modifier. I will test this when I have the chance.

I “believe” that the disk this close to the strobe “may” yield a more specular look to the light like my focusing rod modifiers. When I have my focusing rod strobes close to the center of the modifier I call it ‘focused’ which is much like this configuration.

At this point it’s way too early to give my impressions of the light quality, simply because I haven’t tried it! But from a construction standpoint I feel that for 95.00 USD it presents a great value. Is it ‘better’ than this brand or that brand? I can’t say, but will say that IF the light quality is great to excellent I will add this to my workflow when it’s the right tool for the right job. More to come…..later.

  1. Hi Mark, thanks for the review. I am eager to see sample shots… especially if the theory that moving the deflection plate would be similar to a focus rod. One question. Based on your photos, it looks liek i could remove the Bowens mount adapter from the ring and attach a different adapter? (say one for PCB? Could you confirm?
    Thanks!

    • Hi Zarli yes the speed ring is easy to change. Thanks for your question, I’ve actually added it to this post to help others. I’ll let you know my impressions of the light quality once I run my test. I have a feeling it will be high quality and may replicate a focusing rod to some degree.
