I'm going to try optics to increase the throw on this Amilite. Ideally, it should give a good throw but still leave at least a small area of dim spill. Are there any shops/vendors/distributors for Carclo optics or the NX05? I only see one vendor for the Fraen LP and it doesn't even say whether it'll fit a 20mm size head or whether a holder is required, etc. Can anyone educate me about this? (btw, tried search and it wasn't too helpful.)
