As any engineer will tell you, the best answer always begins with "It depends..."
Do you want a schematic to build it yourself, or a ready to use, drop in product?
If ready to use, do you want a small lot product (i.e., built in small quantities, typically by a hobbiest - small business) or production product (you can buy 1,000 if you needed to)?
How important are form factor, efficiency, cost? What about features? The quiescent current limit might rule out some microcontroller-based designs, but maybe not - the sleep mode on many families is surprisingly frugal.

Thanks for the reply.
I am looking for a drop-in product and can design a flashlight to mount it properly. Efficiency should be 85%+, and I need a feature to allow user adjustment of current/LED brightness levels, either through a resistor value or a pushbutton. Cost is not very important, as it will be a high-end flashlight. I will probably be starting with a quantity of 50, and possibly more if demand dictates.
Any help you can provide is greatly appreciated. I was considering the following:

Any thoughts?
