Im sure this isnt a revelation but Ive been struggling finding a nice low-light setup for my 8 dats. The lowest watt bulb still freaked them out so I decided to try 2 sets of xmas LED lights...wow...very nice shimmering effect and the Dats are not bothered by them at all...just thought I would share this I know a lot of you dat owners are having the same problem..best 12 bucks I ever spent...video coming soon
