I'm seriously considering buying Ken Rizza's lathe-track setup with at least one light. He's got a couple of choices for the lights, one being $120 and one being $55. Near as I can tell, the difference is just the number of LEDs and the more expensive one is just brighter and not different in any other way. To anyone who's got these lights, is the brighter one worth the extra $$$? If you've got either one, do you regret your choice? If so, why? Thanks in advance.
