I found that the liter milk bottle top/cap (Australia) above fits perfectly onto the LED LENSER P7 with no modification required : )
I used different intensity of orange color gel film in this example because I will be mainly using it as fill under tungsten lighting environment. There are many other color from the Resco sample pack.
In the test sample shot below, I was using my right hand on my camera and left hand holding the LED torch. I zoom the torch right out to give a large spread of light because I was standing quite close to the subject.
You can buy the LED LENSER torch or similiar light from camping stores or from ebay.
I hope someone may find this entry useful.
I will try to use this on my future wedding reception shoot or night light shoot and see how I go with this.
Lately I've seen LED video lights that use 4x AA batteries or other video type of batteries from Sony or other brands of Video batteries. These LED lights have an adjustment dial where you can adjust the output power of the light and I believe this may be a good option. The mount of these lights are not very well made but for the price (about Aus $40 - $50 from ebay), I think it is well worth.
Below is a shot captured using such light (on the bride). The light used on the groom was the torch I've mentioned early in my post.
