Re: Is the Aleph upgradable with the new Nichia?
bippidie,
There is no reason the Aleph can't be compatible with the new Nichia since the Aleph is an open platform. However, there may be significant modifications required to the reflector or ES-screw for proper function so I don't know what the answer to your question will be at this time. I have yet to receive any samples from Nichia so I am in the dark.
I have messed with the new Cree 7090 package and found that as Newbie mentioned in another thread that the relatively deeper reflectors (in the case of Aleph, the 20 mm and 38 mm) do a better job in capturing more of the emitted light for columation. I believe a better solution would be design specific reflectors for the 7090 and I have some prototypes now on order. I am anxious to see if I have a clue as to what's what! /ubbthreads/images/graemlins/blush.gif I am exposing myself to possible embarassment on even mentioning a new reflector. Perhaps it will be lost in the mail and never seen. /ubbthreads/images/graemlins/grin.gif
Like Knifebright, my most common needs are for a flood beam. However, I need a tighter spread than a lambertian or even 100 degree viewing angle so some bending of light is required. Currently I have a SF Beam shaper over a 20 mm reflector and it provides an ideal flood for my needs. I also have the useful option of popping off the beam shaper when I need illumination at some distance. At night or in good dark, this is all I really need. On Maui, I stopped carrying my 38 mm A-3-1x123 and figured upon my return home that I wouldn't need to carry a tighter and brighter light in addition to the 20 mm. I quicklly found that in the shop and around the house that I needed a brighter and intense spot for times during the day as well as night when I needed to overcome levels of ambient as well as penetrate dark shaddows. We used fixed lighting during the day as well as night and I guess it is no surprise that portable lighting is also handy regardless of the sun's location; needed ilumination levels will vary accordingly.
Oops, OT drift and ramble there! /ubbthreads/images/graemlins/blush.gif
