I recently ordered 2 of these lights and am expecting them to arrive later next week. http://www.ikea.com/us/en/catalog/p...ts/20169658/It was suggested that I diffuse these to spread the light out some. I have seen some people use coin tube caps to do this, but I don't have any coin tubes to steal the caps from. My thought was to either use some old clear white plastic film canisters by just sliding over light and taping it down, or use ping pong balls. My question is has anyone tried the ping pong ball approach to this? How well does this work? Could Someone post a photo of what your light looks like with the ping pong ball attached? This will give me an idea of how to attach it properly. Thanks...Mont Edited by MontCollector

Wait for Ray he has a why to defuse them inside the light, then if you need more just put a Kleenex over the light with an elastic band that's what I did and works.

MontCollector I just cut the ping pong ball directly in half. then tape the halves to the lights. that works very good it also cuts the light. hope this helps. MontCollector do you know a surveyor or a engineer. if you do they have a plastic used for engineered drawing for all weather. ask them for a piece. it is the best diffuser. see it is the same as Canson Opalux Translucent Paper. which is really a plastic. it is one of the best diffuser out there on the market.

I don't have a photo close by, but I just used an exacto knife to cut away a big enough hole in the ping pong ball for it to slip on the Jansjo light, then it stays on without tape and I can remove it pretty easily if I want.

As mcshilling says, I do two levels of diffusion with the Jansjos. First level is to remove the lens and replace it with a disk of Canson Opalux. This is enough diffusion for most coins. If more diffusion is needed, I place a large piece of Opalux near the lens or between lens and coin, and shine the Jansjo(s) onto this.

I'm using doubled up ping pong balls. One is cut with a hole smaller than the diameter of the lamp to help hold, the other is cut in half.  |

Thanks all. I think I'm gonna try the Ping Pong ball method 1st.
Rocky and Chequer both those methods sound very doable and easy.
Dave700x Do you use both methods that Rocky and Chequer mentioned because you have 4 of them? Would you use the same method with only 2?

I did use the same method with 2 jansjos. I'm using 4 now to fill in the voids, especially with slabbed Morgans.

Fabric store remainder bin - there are often offcuts of Muslin (it's the slightly off white fabric used for making models and underlayments). You might need two layers.
Cut a circle and use a rubber band to gather it back around the bulb head - the way the Jansjo necks in provides a perfect attachment point.

So my light came in and I'm not so sure about them. They put out more of a yellow light. My My old setup is geared more towards the white light side. Here is a photo of the same coin under the different lighting.  The Jansjos brings out the toning on the edges more accurately, but this coin is BU and does not look yellow in hand. I do have the Jansjos filtered with white ping pong balls. So I figured this may have something to do with the color of the light. However when I take off the filters the color remains the same. All In all I think my old (white light) setup, more accurately depicts silver better. While the Jansjos are much better at representing the toning. What do you all think? Thanks...Mont Edited by MontCollector

Ok so I messed with the white balance on the camera. I think I am on the right track...Thanks crazyb0  Still need a little more adjustment...like a manual white balance, but my camera batt died. This is set on "Tungsten" lighting in my camera.  Shows color much better IMO. |

I did a custom white balance on my camera and what a difference that made. I think these will work.  This is a very accurate representation of what the coin actually looks like in hand. I love how you don't have to struggle to show the toning with these lights. I didn't even have to angle the coin this time  |
