Reflector Questions for Bike Light

Hey Guys

Thanks for posting all your knowledge up here on the boards

I thought I'd share some experiences since emarking on the mission to design and build my own LED bike lights and also ask a couple of questions

After reading a heap of stuff on various forums I came across a the Australian distributer for Cree LED's (Cutter electronics) and seeing I'm in Oz I thought I try using them

The specs looked great so I ordered a few to try as well as some optics

Well at first I was impressed as they are definatly bright to look at but after housing them and testing them out in the bush I was left wanting more light

I spent hours going over all the specs and started planning quad housings and even thinking I might need 2 of them

But before ditching my neat little single housings I thought I'd try some IMS reflectors

So I order a 20.5 and a 27 from the sandwich shoppe and I thought I'd grab a Tbin Lux III just to try

Well the 27mm wouldnt fit the cree so I made the hole a little bigger so it would fit and upon testing it was a failure no goog at all

So I tested the Luxx III with the 20mm reflector and "WOW" I was impressed

Went Riding with it and 1 of the crees and I was thinking maybe I could get by with 2 of these

So I am waiting for another to arrive to see if I'm happy with 2 of them on the bars but I am now wondering about reflector options

I cant seem to find the angles for the IMS reflectors

Am i correct in thinking the 27mm is the tightest spot with the 17mm being the flood and the 20.5 is in the middle?

Thanks for your help

but won't an oval beam optic make the overall beam nicer and better for riding?
