I will use your method colin55 when i'll build a different chandelier, that will have 2 paralel strings of LED in series.
That will be a 115 LED in series in each paralel string, it will be big lol.
About the white LED at 17mA, they would not give full bright at 17mA, at least my LED, i've tested, and if i install a 470Ohm resistor the LED look kinda dim, but if i install a 390Ohm resistor, the LED becomes ultra-bright. And if i'm not mistaken the LED and the resistor got warm, i mean, very warm, when i've used the 390Ohm resistor, but the LED kept on all the night and didn't burn.
