Ideally our light source would need something that has an LED with a laser like quality as one bulb, that can be plugged into a power supply preferable the mains.
210 Lumen Aluminium Torch £49.99, This maybe the perfect starting point for our experiments as its not to powerful but should give greater results than with the V9 Micro laser pen and its a little cheaper.

750 Lumen CREE Torch £69.99, This looks like it will be really powerful with 750 Lumen, maybe too powerful!

LED Lenser V9 Micro Laser Torch £9.99, This is what we have used for our earlier experiments. The results were there but not bright enough.
