I have a Ledwave X55 for over a year now. It seems to be the same as the Nuwai TM-301X-5, but there are some differences.
One of the most important ones is that the Ledwave has a glass lense and not a plastic one. Anodizing is somewhat better too.
It is definitly a great light which produces a wall of light with very low focus.
I would buy it again.
