hi ,good project to work on,but i think instead of voltage you must concentrate on charge stored,you can use 1 farad /5.5 v capacitors in parallel and you have to use 2 led in series (and now make parallel combinations of such 2 leds)in india i could get this cap at http://www.onlinetps.com/shop/index.php?main_page=product_info&cPath=95_96&products_id=667 ,.u could also get it at your place ,just search though its hard to find value ,u can go for higher capacitance like 10 f but low voltage so that u dont need to apply resistance.
