I REALLY like their ZForce NiMH system that uses the HID light (equivalent to a 40watt halogen)... I even emailed the owner of LaserEdge and asked if he would be using Metal Hallide lights ...
His response:
"Thanks for the email! Sorry, no changes on the metal halide systems as of yet. I am still looking for a bulb/ballast combination that would be economically feasible to offer. As far as new products go, however, I will be offering a dual beam headmounted system in the very near future. Talk to you later!
