Well, fortunately the man who laid out the $500+ for his "Ferrari" knew how much his battery weighed. I don't deny the expensive lights are nice and worth it to some people but my system now has a 9 hour lifetime and It has set me back $300. It doesn't swivel that is true, but I don't need it to and prefer it not too since I ride a recumbent and a light that stays put is better for my purposes. If I wanted my system to run 12 hours like the $500 MOAB all I would need to do is spend $60 for another battery pack and I would have 13.5 hours and still be $150 dollars cheaper. Sure I wouldn't havve an LED, but I use an EL-500 as a failsafe light in case the HID has problems while I am cruising down the road and I would at least have SOME light if that ever happened in an emergeny. Anyway, it all depends on what kind of rider you are. If you like all the bells and whistles and don't like to tinker and don't mind spending a few extra bucks, go with a name brand. If you don't mind doing a little finagling yourself and need the cash and want a simple light, go with the trailtech.

For me personally none of the name brand lights are designed with recumbents in mind and so the battery bags and mounts often times are not what I want anyway, the trailtech is better in that area for me since I don't have to pay for all the extras which I will likely not use anyway.
