@sut
Many thanks....I try to help were ever I can and adjusting a few
components on a simulator is only a few minutes job that can
save some people hours of trial and error.
Just a side note that R3 can be anything from 0 to about 10 ohms
depending upon the brightness of the low setting required or
remove switch and resistor if not required. The above circuit
runs at about 850ma and 120ma on low but has not been tested in
practice by me using the above components, (I do trust my
simulator though and it has never been too far out of whack).

@Barbados
Just a quick shout to ask if you built the above driver ? ....
Did it work ok ? .... current readings ? .... would be nice to
know if it was okay with the 2n3055 .... really curious.

@NessProjects,
Thanks for checking in, as you may have guessed i have the
transistors, the resistors however are another matter (
challenges of living on a small island).
I am still trying to source them on the island, if by weekend i
have not sourced them, I will mail order them from overseas.
Promise to keep you updated.
Best
Barbados
