Those are actually pretty slick and capable. The main thing with cra-Z home brew is that you can shred just as fast at night as you can in the daylight. If you're wanting to just traverse trail and explore...there are tons of really nice factory options for a decent price. The Minewt being a good example. AYup's are decent too. The other thing is...if you ride solo in really dark forest, your eyes adjust and you don't need as much light. If you ride with somebody blasting 1000lm and you're trying to ride with 400...you're going to feel sketchy.
