Need advice on ajustable flood light

I'm looking for an adjustable flood light which can go from very wide to very narrow flood to spot, multiple modes starting with something low like 5 lumen, runs preferably on AA's (oherwise CR123) and with a diameter in between 18mm to 22mm to fit the fenix headband. I prefer something that runs on AA's since I wear glasses and the extra lenght means it will reach further ahead and avoid causing glare. Any suggestions?

The only things that I can think of that even come close to what you are looking for are the coast led lenser p14 although that is a little fat and also doesnt go as low as 5 lumens I think, or the MG MC-E PLI which doesnt use AA's doesn't go as low as 5 lumens but is probably thin enough......maybe a 2xaa mag with a drop-in and a nite ize switch.....I dunno, not a great choice either really. Do you really have to have all the modes? The fenix E20 is a really nice light and the focusable head does give u some control of the brightness in a way.
