What is the Parabolic Light Diffuser, and does it really make a difference? Is it just a metal grate covering the light?

The metal grate is in front of the bulb, and permits lots of light for the user without annoying everyone else in the room. That feature is a huge improvement over previous models. The parabolic diffuser is the domed part of the lamp behind the bulb.

It is a curved polished backing behind the bulb that scatters the light for a more uniform light

I've never needed a diffuser for this flash. In fact, good luck finding one, given the specific shape of the light ring. If you really wanted one, I guess you could innovate, but frankly I don't see the need. The previous answer to this mentioned the color of the light from this flash making human subjects appear too blue. Personally, I think this is a matter of properly setting the white balance in camera . . . but if not, it's an easy correction in Photoshop if you are shooting RAW.

Sorry, I didn't know there was a difference. It's whatever the seller listed. BTW, I really like the light. Sorry I couldn't be more help.

I am not sure what a diffuser is, but there is a plastic disc on the bottom. It is not clear. It is kind of white but the light shines through it. I cant think of what the material is but I would know it if I heard it. Hope this helps.

In my opinion I would say no. The grill that this unit comes with already has a diffuser built into it at the location of each burner. The grill still had a couple hot spots, but I think it's about as good as it's going to get. As for just using it with pots / percolators / etc. I've used it pretty extensively and have not needed a diffuser. The flame ring can be a little wide for small pots or a small perc, so in that case it might be something you want to consider. Hope that helps.

It has a sliding control that moves from high to low, but even the "simmer" position is pretty high. I purchased a cast iron diffuser for mine and it works great to moderate the temperature of the flame.

The entire cube will function as a light diffuser on all sides, top and bottom. I have used it outdoors with morning sunlight as my light source. It is not "see through" as in transparent.

It comes with a white plastic diffuser that covers the bottom. You do not see the light bulbs when you look up at the light.

It is going to show light through it but it is heavily diffused. I put this up to block sunrays that come in at an odd angle blinding us. Now my hall window still provides nice soft light but is a fraction of the brightness and keeps temps down.

It comes with the basic transparent one which made by plastic, but not a big professional diffuser.

yes, and it is actually better because it burns cooler. love this fixture!!!

As I understand it, light as it passes through the polarizing film realigns the rays from random angles into a uniform direction much like going from criss cross lines into all flat, parallel lines. A diffuser would likely jumble up all the orderly light rays again. My theory is that it would not be effective if placed before the diffuser. But... You never know unless you try. Might still have some unpredicted appealing effect.

This is purely low light. It works by displaying images in high contrast, though it also has red leds to "illuminate" things are a longer range, which is barely visible.Despite it's "infrared" claim, it has _no_ infrared capabilities. I've tested it with an electric stovetop, producing a very high temperature gradient with no light in the visible range, and there was absolutely no difference in the view from the hot top to the cold ones.It does work really well for low light.

It lets light through completely. It's see through until your shower steam makes it hazy but the light isn't affected.

It is a spot light, you would not be pleased with the narrow beam. However, if you diffuse it with wax paper or something similar, the beam is much softer and wider.

I have this one over some cacti in a ten inch reflecting hood I think it casts any diffuse light from the bulb downward to the plants over a larger area than any of the smaller hoods

Yes. The diffuser is a solid piece of matte plastic with no screw in the middle. The light is beautiful. We put it on a dimmer. However, you have to order the fixture separately! We didn't realize this and were surprised to just get the shade in the box. It looks great in my teen's bedroom.
