i am thinking of making a constant voltage supply.. i could always convert one of the CC drivers it should not be difficult.. vreg is much easier than c.reg. The reason i thought CC would be good is that the startup current would not spike like typical .. but the voltage would swing around.. i think i'll be doing a test of CC and see what happens.. but i'd be very interested in getting in-touch with somebody that already did this testing.

a pair of 168s doesn't have enough energy but it does sound neat.. nice light for the short runtime it'd last. the 9AAs i have is about twice the WH of two 168s.. so i guess i might be building a driver or converting the likes of this one to voltage v. current.
