This simple device does the job of a reflector and set of 4 honeycomb grids. Having the ability to focus the light from a 10 degree spot to 40 degree flood is very cool. So far I've used this adapter on LED continuous lights and on strobes. Works great on both. If your strobes' modeling light extends too far forward, be careful because the longer bulbs prevent closing the adapter all the way down.

The Bowen's mount impact Fresnel Spot is not going to take the place of your honeycomb grids but does offer a focusing beam control option at a very reasonable price point! Complete with a CTO and teal green filter that easily attaches. Build quality is fair so I am not sure how long it will last but for the price you can't go wrong!

I'm currently using this with my Phottix Indra monolights to achieve a very focused look. They work very well, though I'm concerned about the longevity of them. Glass is great, but the body is plastic.

I am a recent convert to the world of COB lighting. I love the look and focusing ability of fresnels but wasn't sure you could get that with COB lights. This is a great solution to add on to your existing lights. Does the trick nicely. Does it make your cheap light into an ARRI? No, but it works really well.

Let me be the first to say that if your looking for a good way to control your lights these Fresnels are very good for all around production. The spot function was exceptional. Also came with color gels. Would totally reccomend.

good works.

works well
great light modifier
compact
light weight

The low price of this light modifier makes it an attractive choice compared to a hot light Fresnel provided you have an light that uses Bowen, S-mount attachments. I used it only with monolights. At the 10 degree end I throws wonderfully sharp shadows, and even when zoomed in to 40 degrees the shadows are defined, if not as hard. You do have to be careful about the modeling light, however. If your modeling light sticks out more than 3 inches from where the mount attaches, then you will be limited in the zoom range, with the limit on the wide end.

Not a really heavy fresnel, but well made and a good bargain. Mostly plastic which is fine for me since I'm using LEDs and dont need to worry about heat.

I did my test on the Genaray Powerhouse PH300-LED using a light meter at 100% intensity.

According to the light meter (and to my eye) the 
Impact Fresnel Spot S-Mount Attachment at full flood is equal in light output to the Aputure Fresnel 2x at 20 degrees.


The reason I compared the Impacts flood to the Aputures 20 degrees is because the Genaray Powerhouse LED light is the brightest at these settings (I tested the light output at numerous degree settings).    Therefore I am comparing brightest to brightest - apples to apples.


It is equal beyond 1 meter.  For some reason at 1 meter or below the Aputure Fresnel 2x is brighter by 67%.


Therefore for the price and space and weight savings (the Impact Fresnel weighs almost nothing and is teeny tiny as opposed to the Aputure Fresnel 2x which is built like a tank and is as big as a tank).


In terms of light leakage and cutting, I didnt notice a difference between them on the Genaray Powerhouse.  The results may be different on the Aputure 300D and 120D.


My tests are as follows:
1 Meter: Aputure 2x = 50,000 Lux, Impact = 30,000 Lux
10 feet: Aputure 2x = 1,500 Lux, Impact = 1,500 Lux
20 feet: Aputure 2x = 1,000 Lux, Impact = 1,000 Lux
24 feet: Aputure 2x = 600 Lux, Impact = 600 Lux


Therefore if you are using the same light as me, the Genaray Powerhouse, then just buy this Fresnel instead of wasting money on any other fresnel.
