LED Ring testing, again

I modified my DIY LED ring so that I can use a 3S LiPo battery as the power source instead of the 9V battery I was using before. This gives me more light as a fully charged 3S LiPo has a typical voltage of 3x4.2V =12.6V. Testing confirmed that the light was much brighter with the new power source. Obviously I had to test the light so I took a couple of shots of my Access Music Virus TI Snow synth module.  

Using LED rings for lighting

I recently bought some LED rings from Dealextreme and built a DIY LED ringlight with them. I attached two different rings to a CD case using hotglue. The CD case was made of translucent plastic so I sanded the cover plastic to give it a nice and smooth texture. This way the cover works as a sort of diffuser. I still need to cut a hole into the CD case to make it attachable to a cheap UV filter I also bought from Dealextreme. Another idea I got was that I should build two of these ring sets and find a way to attach them to some stiff but flexible "arms". That way I could achieve similar lighting possibilities that Canon's professional macro flash MT-24 EX offers. Anyway, even with just one ring you can achieve pretty good results. I took some photos of different toys: Turtles, Littlest Pet Shop figures and Luigi from Super Mario Kart. Pics below. I've edited these all slightly. I wanted to have rich and full colours so I increased the vibrance and saturation ever so slightly. It's amazing how much dust these things gather. You cannot see it with your naked eye under normal conditions but with a macro lens shot from a short distance the crap these things gather becomes obvious. Luigi really should wash his face more often! I removed the biggest dust particles using Lightroom's spot removal tool. I also used the tool to fix some spots that were missing paint in the toys. I power the LED ring with a 9V rechargeable NiMH battery but I have plans to add a connector for a 3-cell LiPo battery. This way I will get more voltage which will result in more brightness from the LEDs. I have yet to try this light when shooting insects. I'm not sure the intensity of the light is enough, at least not for fast moving insects. For stationary guys maybe, we'll see.
