Here are 3 photos showing no light effect and then 2 with a green and then blue colour, again sorry about the quality as I was holding the camera while it did a longer shutter photo take.
I had the lights on in the sunroom at 6pm so just was dark and had to take the photos with no flash (as the flash drains all the effect away), so hopefully you can see the effect.
Down at the local pub where there is a Tron LE near the bar has no direct sunlight and quite a dark corner so it is quite effective and on the net I have read once you play the TRON LE in a daytime environment with natural light the lighting isn't as effective. Though these photos are of one 10m cable with each each going into the bush I still think the Tron LE may have a brighter light engine. But at least I can install the fibre and always try a bigger light engine with minimal effort at a later date.
