I hadn't seen that one before and don't know the company, so I had to look it up. For the price, I'd certainly hope it's a good light, but know nothing about it. It looks like it has a hefty battery pack, so the output and runtime they claim sound believable.
I don't think there are many headlamps of a similar configuration.
The Fenix HP30R is capable of similar output, but I think it has to reduce output in max mode slightly after a while to avoid overheating. It doesn't have a super-concentrated beam though.
