I emailed Reikan myself regarding light as i have none myself, below is his reply:

"Regarding the lights - the most important thing is stability of lighting. You shouldn't use main powered LED lights or fluorescent as they can flicker and cause issues, but if you have a couple of spotlights that should be fine (you don't need studio lights for example).

Natural light generally tends to work best, but you need to ensure it's a fairly static level (e.g. not period of bright sunlight then clouds). Also, if you're testing outdoors, you want to make sure the target is very firmly attached and doesn't blow around in the wind.

A lot of the development testing has been done with a couple of halogen spotlights on the target, so this is definitely a viable option."
Hope that is of some use to everyone
